问：您对互联网隐私有何看法？
我们认为，互联网隐私最重要的两个组成部分应该是：
保护您的私人对话免受官员、雇主等第三方窥探。
保护您的个人数据免受第三方（如营销人员、广告商等）的侵害。
Telegram 的目标是创建一个真正自由的即时通讯工具，拥有革命性的隐私政策。
问：关于GDPR呢？
《通用数据保护条例》（GDPR）于2018年5月25日在欧洲生效。由于我们创建Telegram的初衷就是为了捍卫我们的隐私权，因此我们无需做出太多改变。我们不会利用您的数据进行广告定位，不会将其出售给他人，并且我们不属于任何黑手党家族“企业集团。”
Telegram 仅保留其作为功能丰富的云服务所必需的信息。例如，您的云聊天——以便您无需使用第三方备份即可在任何设备上访问它们，或者您的联系人——以便您在 Telegram 上给他人发消息时可以依赖您现有的社交网络。请参阅我们的 隐私政策以获取更多信息。
你可以使用@EURegulation来：
请求获取 Telegram 存储的所有数据的副本。
联系我们了解数据隐私。
问：Telegram 上有非法内容。我该如何将其删除？
所有 Telegram 应用都具有“举报”按钮，让您只需轻点几下，即可将非法内容标记给我们的版主。
在安卓版的 Telegram 上，点击消息并从菜单中选择 举报。在 iOS 上，长按消息。在 Telegram 桌面版、网页版或 macOS 版 Telegram 上，右键点击消息并选择 举报。然后选择一个合适的理由。
您也可以使用我们的自动下架邮箱 abuse@telegram.org。如果您发送的是邮件下架请求，请务必包含 链接（例如 t.me/... 或 @...），指向您认为需要我们版主关注的 Telegram 内容。
欧盟用户欢迎学习《欧盟数字服务法用户指南》以了解相关的报告选项。
注意：如果有人冒充您进行诈骗，请联系@NoToScam
问：我如何根据欧盟第2021/784号条例提交申请？
欧洲议会和理事会2021年4月29日关于应对在线传播恐怖主义内容的第2021/784号条例（在线恐怖主义内容条例，或称TCO条例）允许欧盟国家的当局在发现恐怖主义内容位于Telegram的公共平台时，向其发送删除请求。我们还指定了第三方——欧洲数字服务代表（EDSR），协助我们处理与TCO相关的沟通事宜。
因与TCO法规相关的出版物被下架的用户，可以申请了解其出版物为何被认定为恐怖主义内容，以及如何对下架决定提出异议：
致信位于比利时布鲁塞尔71号胡阿尔特-哈莫瓦大道1030的EDSR，或
通过联系 @EURegulation 机器人，并在 Telegram 上使用 /tco_ask 命令。
请求可使用英语和法语提交。
问：一个机器人或频道侵犯了我的版权。我该怎么办？
Telegram 上的私人群组和聊天在参与者之间是私密的。我们不会处理与它们相关的任何请求。然而，Telegram 也支持 贴纸集、机器人、频道和公开的群组。
如果您看到任何属于 Telegram 公共平台的一部分的机器人、频道、贴纸集或其他内容侵犯了您的版权，请向 dmca@telegram.org 提交投诉。请注意，此类请求仅应由版权所有者或受其授权的代理人提交。
问：你们处理来自第三方的下架请求吗？
我们的使命是提供一种在地球上任何地方都能正常运行的安全通信方式。为了在最需要的地方（并继续通过 App Store 和 Google Play 分发 Telegram），我们必须处理合法的请求，以移除应用内非法公开内容（例如，贴纸包、机器人、群组和频道）。例如，我们可以移除侵犯知识产权的贴纸包或色情机器人。
Telegram 上的公开内容，例如用户上传的贴纸包、频道以及第三方开发者创建的机器人，均不属于 Telegram 核心用户界面的一部分。每当我们收到关于潜在非法公开内容的举报时，我们会进行必要的法律审查，并在认为适当的情况下将其删除。
请注意，这不适用于当地对言论自由的限制。例如，如果在一个国家批评政府是非法的，Telegram 将不会成为这种出于政治动机的审查的一部分。这违背了我们创始人的原则。虽然我们会屏蔽恐怖主义（例如与 ISIS 相关的）机器人和频道，但我们不会屏蔽任何和平表达不同意见的人。
问：我的机器人或贴纸包被不公平地封禁了，我该怎么办？
如果您认为我们无故封禁了您的机器人、频道或贴纸集，请发送邮件至abuse@telegram.org。
问：你们处理数据请求吗？
秘密聊天 使用端到端加密，因此我们没有任何数据需要披露。
为了保护未受端到端加密保护的数据，Telegram 使用分布式基础设施。云端聊天数据存储在全球多个数据中心，这些数据中心由分布在不同司法管辖区的不同法律实体控制。相关的解密密钥被分割成部分，并且绝不会与它们所保护的数据存储在同一位置。因此，需要来自不同司法管辖区的多项法院命令，才能迫使我们交出任何数据。
得益于这一结构，我们可以确保没有任何单一政府或同心协力国家集团能够侵犯人们的隐私和言论自由。只有当问题严重且普遍到足以通过全球多个不同法律体系的审查时，Telegram才可能被迫交出数据。
至今，我们向包括政府在内的第三方披露了 0 字节的用户消息。
有关您的数据如何受到保护的更多信息，请参阅 Telegram 隐私政策 和 Telegram 首席执行官的 这篇帖子。
Telegram 基础
关注我们的技巧频道以了解更多关于 Telegram 功能的信息。
问：我能写信给谁？
你可以给手机通讯录中拥有 Telegram 的人发消息。另一种联系人们的方式是，将他们的 Telegram 用户名输入到搜索框中——你无需知道他们的电话号码即可做到这一点。
问：谁可以联系我？
如果他们知道你的电话号码或者你先给他们发消息，人们就可以通过 Telegram 联系你。
如果他们不知道你的电话号码，在以下情况下他们可以找到你：
当你们两人都是同一个群组的成员时。
如果您设置了一个公开用户名。其他人可以使用全局搜索并按您的用户名找到您。
问：Telegram 会为其他应用程序发送验证码吗？
Telegram 允许第三方服务通过 Telegram 向其用户发送验证码。这些代码仅显示在已验证的'验证码'聊天中，您可以点击立即复制该代码。
未指定名称或头像的服务的代码将显示为默认名称和照片，即'验证码'。
如果您在'验证码'聊天中收到验证码，这很可能是因为您请求登录了第三方服务，例如外部网站、应用或市场。也有可能其他人登录其他服务时，不小心输入了您的电话号码。无论如何，您的 Telegram 账户都是完全安全的——如果您没有请求验证码，只需点击它并选择'举报'，无需采取其他任何操作。
第三方服务决定您的验证码发送方式——而 Telegram 无法控制这一点，也无法让服务了解您的偏好。与经常无法送达且可能被拦截的短信验证码不同，通过 Telegram 发送的验证码会立即送达并且经过安全加密——这使得它们对用户和服务的安全性更高、更可靠。
'验证码'聊天仅用于来自第三方服务的验证码。您的Telegram 账户登录验证码会发送到名为'Telegram'的已验证服务通知聊天中，并且绝不应与任何人（包括其他服务或应用程序）分享。
如果您想通过 Telegram 发送验证码来节省资金并提高效率，请查看 Telegram Gateway。
问：我怎么知道我的联系人中谁有 Telegram？
拥有 Telegram 的您的联系人会显示在联系人列表的顶部。他们还有头像。
问：我该如何邀请我的朋友？
iOS： 基本邀请是简单的短信。它们将按标准出站短信费率向您的运营商收费（除非通过 iMessage 发送）。当然，您还有其他方式邀请朋友加入。尝试通过其他任何消息服务向他们发送下载链接：电子邮件、Facebook、WhatsApp、真正的 Telegram——随便什么。链接：https://telegram.org/dl/
安卓： 打开应用菜单（在聊天列表中向右滑动）> 邀请好友。然后选择您想要发送邀请的应用程序。
你可以给你的朋友一个t.me 链接，包含你的用户名，这样即使他们没有你的电话号码，也能轻松在 Telegram 上找到你。
问：勾号是什么意思？
一个勾 — 消息已发送至 Telegram 云端，如果对方允许通知，则会收到通知。
两个勾 — 消息已读（对方已打开 Telegram 并打开了包含该消息的对话）。
我们没有“已送达设备”状态，因为 Telegram 可以运行在您想用的任意多台设备上。那么，具体检查哪一台设备意味着什么呢？
问：我可以隐藏我的“最后上线”时间吗？
您可以在隐私与安全设置中选择谁可以看到此信息。
请记住，你不会看到与你没有共享状态的人的“最后上线”时间戳。不过，你会看到一个大致的最后上线时间。这既能阻止跟踪者，又能让你了解某人是否可以通过 Telegram 联系到。有四种可能的近似值：
最近查看 — 涵盖 1 秒到 2-3 天之间的内容
一周内最后访问 — 2至3天到7天之间
一个月内 — 6-7天到一个月之间
很久以前 — 一个多月（这也会始终显示给被屏蔽的用户）
问：谁能看到我“在线”？
最后上线规则也适用于您的在线状态。只有当您与他们分享最后上线状态时，人们才能看到您在线。
存在一些例外情况，因为有时很明显你正在上线。无论你的“最后上线”设置如何，如果你执行以下操作，人们都会短暂地（约30秒）看到你在线：
在一对一聊天中或你们双方都是成员的群组中向他们发送消息。
阅读他们在私聊中发给你的消息。
向你们的聊天窗口或你们共同所在的群组广播一个“正在输入…”的状态。
如果你没有与某人分享你的最后上线时间，并且没有采取上述任何措施，他们将永远看不到你在线。实现这一点的另一种方法是屏蔽该用户。
问：我可以删除我的消息吗？
是的。你可以随时删除你发送的或收到的任何双方的一对一对话（在群组中，仍然只有你自己的消息）。你也可以在双方端清除整个聊天记录。在 Telegram 上，已删除的消息不会在聊天中留下痕迹。
除了用于转发消息的隐私设置外，这使得在 Telegram 上交换消息就像面对面交谈一样（没有录音机）。因此，用户不再需要担心多年来聊天记录中积累的数据。对话双方都完全控制着什么属于他们，什么不属于他们的在线身份。
问：我可以通过 Telegram 打电话吗？
是的。您可以进行端到端加密的语音通话和视频通话，并且可以将任何通话转为群组通话，最多可容纳200名参与者——同样受到端到端加密保护，您可以随时验证。
参与者可以在不打断音频的情况下，直接在通话中发送评论和反应。
如果你想要一个群组成员可以随时加入的持续音频聊天，你也可以在任何群组中开启一个语音聊天——这非常适合作为虚拟办公室或休闲聚会场所。
问：我可以向大量受众进行广播吗？
是的。任何用户都可以主持一个直播故事——一种会出现在他们故事中的直播。观众可以在直播期间发送评论和捐赠星币。
频道所有者可以托管直播，拥有无限的观众——这对于活动、讲座、公告和音乐会非常有用。你可以从手机直播，或者使用直播软件（如 OBS）进行完整的制作。
问：我该如何使用表情符号？
在你的输入框中输入 一个词以获取相关的 表情符号建议。 你也可以输入“:”后跟任何关键词来打开 表情符号搜索 – 例如 :heart。
您可以使用此界面来为您的语言中的表情符号建议缺失的关键词（这将打开针对英语的建议，别忘了在左侧菜单中切换到您的语言）。
群组与频道
问：Telegram 群组有什么酷的地方？
电报群组最多可拥有 200,000 名成员，是极其强大的通讯工具。以下是使它们在消息传递领域脱颖而出的几个关键特性：
统一历史
发布后编辑您的消息，将其删除，以便对所有人隐藏。
跨平台可用性
随时随地，通过任意数量的手机或桌面设备访问您的消息。
即时搜索
即使在数百万条消息中也能找到您要找的消息。按发件人筛选，使搜索更轻松。
回复、提及、话题
轻松追踪对话，无论群组大小如何，都能保持沟通高效。
智能通知
静音群组，仅在有人提及你或回复你的消息时才接收通知。
置顶消息
您可以将任何消息置顶，使其显示在聊天界面的顶部。所有成员都会收到通知——即使他们已静音了您群组中的普通消息。
管理工具
任命管理员，他们可以批量删除消息、控制成员并置顶重要消息。以精细的精度定义他们的管理员权限。
反垃圾邮件工具
在大型群组中，启用 强力反垃圾邮件以在您的聊天中使用 Telegram 的全套反垃圾邮件工具。
群组权限
设置默认权限，限制所有成员发布特定类型的内容。甚至可以完全禁止成员发送消息——让管理员在大家面前互相聊天。
文件共享
发送和接收任何类型的文件，每个文件大小最高可达 2 GB（或使用 高级版）4 GB，并在您的其他设备上即时访问。
主题
将群组讨论拆分为主题 — 每个主题都有自己的聊天记录、共享媒体和通知设置，就像经典论坛一样。
公开群组
获取短链接并将其设为公开，例如t.me/publictestgroup。这样，任何人都可以查看群组的完整聊天记录并加入发送消息。
群组助力
成员可以通过他们的 高级订阅为群组助力，为所有人解锁功能——例如 发布故事、自定义表情包、语音转文字和自定义群组外观。
通过机器人进行自定义
使用我们的 机器人 API 和 内联机器人 为任何特定需求创建自定义工具。
Leaving a group cleanly
If you are the owner and want to leave the group, pick a new owner at the same time, so the group keeps running.
Q: What's the difference between groups and channels?
Telegram groups are ideal for sharing stuff with friends and family or collaboration in small teams. But groups can also grow very large and support communities of up to 200,000 members. You can make any group public, toggle persistent history to control whether or not new members have access to earlier messages and appoint administrators with granular privileges. You can also pin important messages to the top of the screen so that all members can see them, including those who have just joined.
Channels are a tool for broadcasting messages to large audiences. In fact, a channel can have an unlimited number of subscribers. When you post in a channel, the message is signed with the channel's name and photo and not your own. Each message in a channel has a view counter that gets updated when the message is viewed, including its forwarded copies.
Read more about channels in the Channels FAQ »
Q: How do I create a group?
iOS: Start a new message (tap the icon in the top right corner in Chats) > 'New Group'.
Android: Tap the circular pencil icon in the chat list > 'New Group'.
Telegram Desktop: Click the menu button in the top left corner > 'New Group'.
Q: Can I assign administrators?
You can add administrators to help you manage your group and define their privileges with granular precision.
iOS: Go to Group Info (tap the photo in the top right corner on the group‘s chat screen) > Edit > Administrators.
Android: Go to Group Info (tap the name in the header) > the pencil icon (in the top right corner) > Administrators.
Telegram Desktop: When in the group, click '…' in the top right corner > Manage group > Administrators.
Q: How do I add more members? What's an invite link?
You can add your contacts, or using search by username.
It is easy to migrate existing groups to Telegram by sending people an invite link. To create an invite link, go to Group Info > Add Member > Invite to Group via Link.
Anyone who has Telegram installed will be able to join your group by following this link. If you choose to revoke the link, it will stop working immediately.
Read more about invite links in our blog »
Q: Can channels and subscribers talk to each other?
Yes. Channel owners can turn on Direct Messages so subscribers can send them private messages — without the channel owner having to share their personal account.
Subscribers can also suggest posts for the channel — including paid suggestions. The owner can review them, edit them, schedule them or reject them. This gives channels a clear way to crowdsource content or work with brands.
Usernames and t.me
Q: What are usernames? How do I get one?
You can set a public username on Telegram. It then becomes possible for other users to find you by that username – you will appear in search under 'global results'. Please note that people who find you will be able to send you messages, even if they don't know your number. If you are not comfortable with this, we advise against setting a username on Telegram.
You can set up a username in Settings and use the universal search box in the chat list to search for chats, messages, and usernames.
Q: What are Collectible Usernames? How are they different from basic usernames?
Collectible usernames work just like basic usernames, they appear in Global Search results and have their own links that can be used outside of Telegram: username.t.me and t.me/username.
They can be bought and sold through third-party platforms like Fragment, giving a simple and secure way to acquire and exchange valuable Telegram domains. Acquiring a collectible username gives permanent ownership, verified by the TON blockchain. Owners of collectible usernames can freely assign them to chats, sell them to others, or keep them for later use.
A single user, group or channel can have several collectible usernames pointing to it at once. Each one has its own t.me/username link and username.t.me address.
Q: How does t.me work?
Once you've set a username, you can give people a t.me/username or a username.t.me link. Opening either of those links on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.
This way people can contact you on Telegram without knowing your phone number.
If you don’t want to set up a public username and don’t mind sharing your number, you can also create a t.me link with your phone number in international format – for example, t.me/+123456789. This type of link can quickly open a chat with you from any app, however, it will only work if your privacy settings let others find you by your phone number.
Q: What can I use as my username?
You can use a-z, 0-9 and underscores. Usernames are case-insensitive, but Telegram will store your capitalization preferences (e.g. Telegram and TeleGram is the same user).
Q: Do I need a username?
You don't have to get one. Remember that Telegram usernames are public and choosing a username on Telegram makes it possible for people to find you in global search and send you messages even if they don't have your number. If you are not comfortable with this, we advise against setting up a username.
Q: If someone finds me by username, messages and I reply — will they know my number?
No. Neither party will see another's phone number (unless this is permitted by your privacy settings). This is similar to the case when you message a person who you've met in a Telegram group.
Q: How do I delete my username?
Go to Settings and save an empty username. This will remove your username; people will no longer be able to find you via search. This will not affect existing conversations.
Q: What do I do if my username is taken?
There are two types of username on Telegram, basic usernames and collectible usernames.
Basic Usernames
Telegram basic usernames are distributed on a first-come – first-serve basis.
We understand that certain usernames are part of an online identity for some of us. If your desired username is already taken and it is not registered as a collectible, we can help you acquire it for your account or channel, provided that you have that same username on at least two of these services: Facebook, Twitter, Instagram.
Due to the fact that one account can register multiple bot and channel usernames, we reserve the right to recall usernames assigned to unused bots and channels, as well as openly squatted usernames.
To request a username, contact @Username_bot.
Collectible Usernames
If you want a collectible username but it is taken, you should check if it is available for sale. We cannot assign collectible usernames, they can only be managed by their respective owners.
Q: What if someone is pretending to be me?
If a scammer is pretending to be you, please contact @NoToScam.
Security
If you are an advanced user, you may find our FAQ for the Technically Inclined useful as well.
Q: How secure is Telegram?
Telegram is more secure than mass market messengers like WhatsApp and Line. We are based on the MTProto protocol (see description and advanced FAQ), built upon time-tested algorithms to make security compatible with high-speed delivery and reliability on weak connections. We are continuously working with the community to improve the security of our protocol and clients.
Q: What if I’m more paranoid than your regular user?
We've got you covered. Telegram’s special secret chats use end-to-end encryption, leave no trace on our servers, support self-destructing messages and don’t allow forwarding. On top of this, secret chats are not part of the Telegram cloud and can only be accessed on their devices of origin.
Q: So how do you encrypt data?
We support two layers of secure encryption. Server-client encryption is used in Cloud Chats (private and group chats), Secret Chats use an additional layer of client-client encryption. All data, regardless of type, is encrypted in the same way — be it text, media or files.
Our encryption is based on 256-bit symmetric AES encryption, 2048-bit RSA encryption, and Diffie–Hellman secure key exchange. You can find more info in the Advanced FAQ.
See also: Do you process data requests?
Q: Why should I trust you?
Telegram is open, anyone can check our source code, protocol and API, see how everything works and make an informed decision. Telegram supports verifiable builds, which allow experts to independently verify that our code published on GitHub is the exact same code that is used to build the apps you download from App Store or Google Play.
We welcome security experts to audit our system and appreciate any feedback at security@telegram.org.
On top of that, Telegram's primary focus is not to bring a profit, so commercial interests will never interfere with our mission.

Q: Do I need to trust Telegram for this to be secure?
When it comes to secret chats, you don't — just make sure that the visualized key of your secret chat matches the one in your friend's secret chat settings. More about this below.
Q: What if my hacker friend says they could decipher Telegram messages?
See this page for the latest details about the Telegram Bug Bounty Program.
Anyone who claims that Telegram messages can be deciphered is welcome to prove that claim in our competition and win $300,000. You can check out the Cracking Contest Description to learn more.
Any comments on Telegram's security are welcome at security@telegram.org. All submissions which result in a change of code or configuration are eligible for bounties, ranging from $100 to $100,000 or more, depending on the severity of the issue. Please note that we can not offer bounties for issues that are disclosed to the public before they are fixed.
Q: Can Telegram protect me against everything?
Telegram can help when it comes to data transfer and secure communication. This means that all data (including media and files) that you send and receive via Telegram cannot be deciphered when intercepted by your internet service provider, owners of Wi-Fi routers you connect to, or other third parties.
But please remember that we cannot protect you from your own mother if she takes your unlocked phone without a passcode. Or from your IT-department if they access your computer at work. Or from any other people that get physical or root access to your phones or computers running Telegram.
If you have reasons to worry about your personal security, we strongly recommend using only Secret Chats in official or at least verifiable open-source apps for sensitive information, preferably with a self-destruct timer. We also recommend enabling 2-Step Verification and setting up a strong passcode to lock your app, you will find both options in Settings > Privacy and Security.
Q: How does 2-Step Verification work?
Logging in with an SMS code is an industry standard in messaging, but if you're looking for more security or have reasons to doubt your mobile carrier or government, we recommend protecting your cloud chats with an additional password.
You can do this in Settings > Privacy and Security > 2-Step Verification. Once enabled, you will need both an SMS code and a password to log in. You can also set up a recovery email address that will help regain access, should you forget your password. If you do so, please remember that it's important that the recovery email account is also protected with a strong password and 2-Step Verification when possible.
Check this out for tips on creating a strong password that is easy to remember.
You can also set up a Passkey to log in without an SMS code at all, using your device's PIN, fingerprint or face scan.
Q: Why can jailbroken and rooted devices be dangerous?
Using a rooted or jailbroken device makes it easier for a potential attacker to gain full administrative control over your device — root access.
A user with root access can easily bypass security features built into the operating system, read process memory or access restricted areas, such as the internal storage. Once an attacker has root access, any efforts to mitigate threats become futile. No application can be called safe under these circumstances, no matter how strong the encryption.
Q: What is Cocoon?
Cocoon is a secure, open-source and decentralized AI platform that allows privacy-conscious applications like Telegram to utilize the latest AI models.
Telegram developed Cocoon and uses it to securely power its AI features without relying on third parties, ensuring your data remains protected and inaccessible.
Q: Do Telegram's AI features upload data to third parties?
No. Telegram's AI features including translation, custom tones, AI summaries of long channel posts and Instant View articles, and AI-powered sticker search — run on Cocoon and never send any data to third parties.
When you use an AI feature provided by Telegram, the processing happens within a highly secure, isolated and encrypted environment – your data remains inaccessible.
If you use AI through a third-party bot or mini app, you are using a third-party service, not Telegram. Check that bot's privacy policy for details.
Q: What AI model does Telegram use?
Telegram's AI features like translation and custom tones are powered by Cocoon. Cocoon is a secure, open source and decentralized AI platform that allows privacy-conscious applications like Telegram to utilize the latest AI models.
When you use an AI feature provided by Telegram, the processing happens within a highly secure, isolated and encrypted environment – your data remains inaccessible.
If you use AI through a third-party bot or mini app, you are using a third-party service, not Telegram. Check that bot's privacy policy for details.
Secret Chats
Q: How are secret chats different?
Secret chats are meant for people who want more secrecy than the average fella. All messages in secret chats use end-to-end encryption. This means only you and the recipient can read those messages — nobody else can decipher them, including us here at Telegram (more on this here). On top of this, Messages cannot be forwarded from secret chats. And when you delete messages on your side of the conversation, the app on the other side of the secret chat will be ordered to delete them as well.
You can order your messages, photos, videos and files to self-destruct in a set amount of time after they have been read or opened by the recipient. The message will then disappear from both your and your friend's devices.
All secret chats in Telegram are device-specific and are not part of the Telegram cloud. This means you can only access messages in a secret chat from their device of origin. They are safe for as long as your device is safe in your pocket.
Q: How do I start a secret chat?
Open the profile of the user you want to contact. Tap on ‘…’, then ‘Start Secret Chat’.
Remember that Telegram secret chats are device-specific. If you start a secret chat with a friend on one of your devices, this chat will only be available on that device. If you log out, you will lose all your secret chats. You can create as many different secret chats with the same contact as you like.
Q: How do self-destructing messages work?
The Self-Destruct Timer is available for all messages in Secret Chats and for media in private cloud chats.
To set the timer, simply tap the clock icon (in the input field on iOS, top bar on Android), and then choose the desired time limit. The clock starts ticking the moment the message is displayed on the recipient's screen (gets two check marks). As soon as the time runs out, the message disappears from both devices. We will try to send a notification if a screenshot is taken.
Please note that the timer in Secret Chats only applies to messages that were sent after the timer was set. It has no effect on earlier messages.
Q: Can I be certain that my conversation partner doesn't take a screenshot?
Unfortunately, there is no bulletproof way of detecting screenshots on certain systems (most notably, some Android and Windows Phone devices). We will make every effort to alert you about screenshots taken in your Secret Chats, but it may still be possible to bypass such notifications and take screenshots silently. We advise to share sensitive information only with people you trust. After all, nobody can stop a person from taking a picture of their screen with a different device or an old school camera.
Q: What is this 'Encryption Key' thing?
When a secret chat is created, the participating devices exchange encryption keys using the so-called Diffie-Hellman key exchange. After the secure end-to-end connection has been established, we generate a picture that visualizes the encryption key for your chat. You can then compare this image with the one your friend has — if the two images are the same, you can be sure that the secret chat is secure, and no man-in-the-middle attack can succeed.
Newer versions of Telegram apps will show a larger picture along with a textual representation of the key (this is not the key itself, of course!) when both participants are using an updated app.
Always compare visualizations using a channel that is known to be secure — it's safest if you do this in person, in an offline meeting with the conversation partner.
Q: Why not just make all chats 'secret'?
All Telegram messages are always securely encrypted. Messages in Secret Chats use client-client encryption, while Cloud Chats use client-server/server-client encryption and are stored encrypted in the Telegram Cloud (more here). This enables your cloud messages to be both secure and immediately accessible from any of your devices – even if you lose your device altogether.
The problem of restoring access to your chat history on a newly connected device (e.g. when you lose your phone) does not have an elegant solution in the end-to-end encryption paradigm. At the same time, reliable backups are an essential feature for any mass-market messenger. To solve this problem, some applications (like Whatsapp and Viber) allow decryptable backups that put their users' privacy at risk – even if they do not enable backups themselves. Other apps ignore the need for backups altogether and leave their users vulnerable to data loss.
We opted for a third approach by offering two distinct types of chats. Telegram disables default system backups and provides all users with an integrated security-focused backup solution in the form of Cloud Chats. Meanwhile, the separate entity of Secret Chats gives you full control over the data you do not want to be stored.
This allows Telegram to be widely adopted in broad circles, not just by activists and dissidents, so that the simple fact of using Telegram does not mark users as targets for heightened surveillance in certain countries. We are convinced that the separation of conversations into Cloud and Secret chats represents the most secure solution currently possible for a massively popular messaging application.

Your Account
Q: Who can see my phone number?
On Telegram, you can send messages in private chats and groups without making your phone number visible. By default, your number is only visible to people who you've added to your address book as contacts. You can further modify this in Settings > Privacy and Security > Phone Number.
Note that people will always see your number if they know it already and saved it in their address book.
Q: I have a new phone number, what do I do?
Each phone number is a separate account on Telegram. You have several options if you are using multiple phone numbers:
If you will no longer use the old number (e.g., you moved to a new country or changed your number for good), simply go to Settings and change the number connected to your Telegram account to the new number. Important: make sure you have access to your connected phone number – otherwise you risk losing access to your account.
If you will use the new number for a limited time (e.g., you're on a trip or vacation), there's no need to do anything.
If you want to keep using both numbers (e.g., you have a work phone and personal phone), choose one as your Telegram number. You may create another Telegram account on the second number as well, for example, if you want to keep work and personal chats separated. It is possible to log in to one Telegram app with several different accounts at once.
Q: How do I log out?
Most users don't need to log out of Telegram:
You can use Telegram on many devices at the same time. Just use the same phone number to log in on all devices.
You can go to Settings > Data and Storage > Storage Usage> Clear cache to free up space on your device without logging out.
If you use Telegram with multiple phone numbers, you can switch between accounts without logging out.
If you use Telegram on a shared device, you can set up a passcode in Settings > Privacy and Security to make sure only you have access to your account.
If you do want to log out for some reason, here's how you do that:
iOS: Go to Settings > Edit > Log out.
Android, Telegram Desktop: Go to Settings > … (in the top right corner) > Log out.
If you log out, you will keep all your cloud messages. However, you will lose all your Secret Chats and all messages inside those secret chats when you log out.
Note that logging out does not trigger remote deletion of your secret chat messages on your partner's device — to do that, choose 'Clear History' first.
Q: How do I change my phone number?
You can change your number in Telegram and keep everything, including all your contacts, messages, and media from the Telegram cloud, as well as all your Secret Chats on all devices.
To change your number, go to Settings, then tap on your phone number (just above the username), then 'Change Number'. If you already have a different Telegram account on the target number, you'll need to delete that account first.
Q: How do I delete my account?
If you would like to delete your account, you can do this on the deactivation page. Deleting your account permanently removes all your messages and contacts. All groups and channels that you've created are orphaned and left without a creator but admins retain their rights.
This action must be confirmed via your Telegram account and cannot be undone.
We recommend using a non-mobile browser for this process.
Note that you'll receive the code via Telegram, not SMS.
Q: What happens if I delete my account?
As was just mentioned above, all your data will be flushed from our system: all messages, groups, and contacts associated with your account will be deleted. That said, your contacts will still be able to chat in the groups that you have created, and they will still have their copy of the messages you sent them. So if you want to send messages that can vanish without a trace, try using our self-destruct timer instead.
Termination of a Telegram account is irreversible. If you sign up again, you will appear as a new user and will not get your history, contacts or groups back. People, who have your phone number in their contacts, will be notified. The new user will be displayed as a separate conversation in their messages list and their conversation history with this new user will be empty.
Q: How does account self-destruction work?
Telegram is not a commercial organization, and we value our disk space greatly. If you stop using Telegram and don't come online for at least 18 months, your account will be deleted along with all messages, media, contacts and every other piece of data you store in the Telegram cloud. You can change the exact period after which your inactive account will self-destruct in Settings.
Q: Can I delete my data without deleting my account?
You can delete most of your data without deleting your Telegram account.
To delete individual messages or entire chats for both parties at any time, simply tap on a message (or hold to select any number of chats) and tap on the delete icon, then check the option to delete for both parties.
Many relevant settings are available in Settings > Privacy & Security (on iOS, there is one more step > Data Settings), for example:
To delete your Synced Contacts, choose Delete Synced Contacts.
To delete your Cloud Drafts, choose Delete All Cloud Drafts (on Android, this option is in Settings > Data and Storage).
To delete suggestion metadata about contacts and bots you message frequently, turn off Suggest Frequent Contacts.
For other data:
To delete your profile pictures, open your profile > tap on your profile picture > > Delete.
To delete the stories you posted go to My Stories, then hold to select and tap on the delete icon in the top right corner.
To delete your call history go to Calls > / > Delete All Calls.
Q: My phone was stolen, what do I do?
First of all, sorry about your phone. Unfortunately, the phone number is the only way for us to identify a Telegram user at the moment. We don't collect additional information about you, so whoever has the number, has the account. This means we can't help you unless you have access either to the phone number or to Telegram itself on any of your devices.
I have access to Telegram on another device
Go to Telegram Settings > Privacy and Security and turn on Two-Step Verification. This way the phone number alone will not be enough to log in to your account.
Go to Settings > Devices (or Privacy & Security > Active Sessions) and terminate your Telegram session on the old device. Whoever has your phone will not be able to log in again, since they don't know your password.
Contact your phone provider, so that they block your old SIM and issue a new one with your number.
If you decide to switch to a new phone number, don't forget to go to Settings, tap on your phone number and change your Telegram number to the new one.
I don't have access to Telegram on any other devices
First and foremost, you need to contact your phone provider, so that they block your old SIM and issue a new one with your number.
Wait till you receive your new SIM with the old number, log in to Telegram, then go to Settings > Devices (or Privacy & Security > Active Sessions) and terminate your Telegram session on the old device.
Removing sensitive data
Common thieves usually throw out the SIM card immediately (the phone is harder to locate this way), then wipe the devices and sell them, so there isn't much risk for the data in case of regular petty theft. But if you have reasons to worry about the data on the device and are unable to log out the other device, it is best that you wipe it remotely. You can read more about it here: Apple iOS, Android. Unfortunately, this requires you to have prepared in advance for this scenario.
You can delete your Telegram account if you are logged in on at least one of your other devices (mobile or desktop). Note that inactive Telegram accounts self-destruct automatically after a period of time — 18 months being the default setting.
Q: What does Profile Rating mean?
Telegram profiles show a badge with a numerical rating based on the total volume of successful transactions that user has made with Telegram Stars.
Your profile rating highlights your Telegram level and helps channel owners see that you can be trusted for Suggested Posts and other requests.
Purchasing gifts, sending Paid Messages and funding Suggested Posts with Stars increases your rating. However, if you refund Star purchases or convert gifts to Stars, your rating will decrease.
Q: What is a Passkey?
If you are already logged in to Telegram on a device, you can create a passkey that allows you to enter your Telegram account the same way you unlock your device. With a passkey, you can log in to your device simply by entering a PIN code or biometric data like your Face ID or fingerprint scan.
Passkeys are an additional login method that can be used instead of SMS to instantly enter your account – even if you are traveling or don't have SMS service. Passkeys are also more secure than SMS codes, helping protect users from unauthorized access to their account.
Your passkeys can be managed in Settings > Privacy and Security > Passkeys from any app — which shows detailed info for each of your passkeys, like their creation date and when they were last used to log in.
If you have a password manager like iCloud Keychain, Google Password Manager or another third-party service, you can use it to back up your passkey in case you upgrade or lose access to your device.
With a passkey, you can still request an SMS code in order to log in – so always make sure your account uses an up-to-date phone number that is controlled by you. For even more security, you can add an extra password to your account that is required each time you log in.
Q: What is a Frozen Account?
If your account has been restricted because of reports from other users, your account is frozen. While frozen, you can still read your chats, but you cannot send messages or post content.
You can appeal the restriction directly from the app. Telegram's moderators will review your case. If the restriction was a mistake, your account will be unfrozen.
Bots
If you're a developer, you may find our Bots FAQ more useful.
Q: What are bots?
Bots are small programs that run inside Telegram. They are made by outside developers using the Telegram Bot API.
Modern bots can do a lot more than reply to messages. They can open full mini apps with their own interface, run AI assistants with multiple conversation threads and streaming responses – and much more.
Q: How do I create a bot?
Creating Telegram bots is super-easy, but you will need at least some skills in computer programming. If you're sure you're up to it, our Introduction for Developers is a good place to start.
Unfortunately, there are no out-of-the-box ways to create a working bot if you are not a developer. But we're sure you'll soon find plenty of bots created by other people to play with.
Q: A bot is sending me messages, how do I make it stop?
If you don't want a bot to send you messages, feel free to block it – same as you would block a human user. Some Telegram clients have a 'Stop Bot' button right in the bot's profile.
That said, most bot developers offer commands that silence the bot, check its /help for clues.
Q: Are bots safe?
Yes. Bots are no different from human users that you meet in groups for example. They can see your public name, username, and profile pictures, and they can see messages you send to them, that's it. They can't access your last seen status and don't see your phone number (unless you decide to give it to them yourself).
Naturally, any bot should be treated as a stranger — don't give them your passwords, Telegram codes or bank account numbers, even if they ask nicely. Also, be careful when opening files sent by bots, same as you would deal with ordinary humans. Example: If a bot sent us a file called OpenMe.exe, we probably wouldn't open it.
Q: If I add a bot to my group, can it read my messages?
Bots can work in two modes when you add them to groups. By default, bots only see messages that are meant for them. In this case, you'll see 'has no access to messages' in the group members list next to the bot.
Some bots need more information to work, so developers may disable the privacy mode. In this case, the bot will see all messages sent to the group, and you will see 'has access to messages' in the members list next to the bot.
Learn more about privacy mode for bots »
If your group contains very sensitive information, maybe it's better to avoid adding bots you don't trust 100%.
Q: Are bots made by Telegram?
No. While we have some official bots for specific purposes (like @gif or @Stickers, we don't usually make bots. Bots are made by third-party developers using the Telegram Bot API and platform.
Q: What are mini apps?
Mini apps are full applications that run inside Telegram, built by outside developers on top of the Bot platform. They can look and feel like normal apps, with their own interface, payments, subscriptions and more.
You can find mini apps in the Mini App Store in the Apps tab of Search, open them in full-screen mode, and even add a shortcut to your phone's home screen.
Mini apps can sell digital goods and subscriptions for Telegram Stars. Some mini apps offer affiliate programs — when you share them with friends, you can earn Stars.
Deeper questions
Q: Can I get Telegram's server-side code?
All Telegram client apps are fully open source. We offer verifiable builds both for iOS and Android – this technology allows to independently verify that the application you download from the app stores was built using the exact same code that we publish.
By contrast, publishing the server code doesn’t provide security guarantees neither for Secret Chats nor for Cloud Chats. This is because – unlike with the client-side code – there’s no way to verify that the same code is run on the servers.
As for Secret Chats, you don’t need the server-side code to check their integrity – the point of end-to-end encryption is that it must be solid regardless of how the servers function.
In a post on his channel, Pavel Durov explained why Telegram hasn't published the server code, even as a publicity stunt.
The encryption and API used on Telegram's servers are fully documented and open for review by security experts. We welcome any comments at security@telegram.org
Q: Can I run Telegram using my own server?
Our architecture does not support federation yet. Telegram is a unified cloud service, so creating forks where two users might end up on two different Telegram clouds is unacceptable. To enable you to run your own Telegram server while retaining both speed and security is a task in itself. At the moment, we are undecided on whether or not Telegram should go in this direction.
Q: Can I use the Telegram API?
Yes. Developers for all platforms are welcome to use our protocol, API and even source code. Check out the Getting started section of the docs.
Don't forget about our Bot API that lets you build cool stuff on our platform.
Q: Do you have a Privacy Policy?
Sure. Check this out.
Q: What does the iOS privacy sheet mean?
Apple created privacy sheets to inform users about what data apps may collect, but information there is vague and can be misleading. You can see a detailed explanation of Telegram's sheet here.
Q: Why do you have two apps in the Mac App Store?
One is our app for macOS, the other is Telegram Lite, the macOS version of our multi-platform client. Both apps are official. Both started out as unofficial applications by two different developers and vary in design and functionality.
Telegram for macOS supports many platform-specific features, such as the MacBook Pro Touch Bar, gesture navigation, integration with the Mac's Share menu and more. It has every feature from the iOS version of the app including Secret Chats.
Telegram Lite is a lightning-fast app, optimized for work-related tasks and handling large communities. It offers a three-column interface, perfect for multitasking and quick access to media, files and links shared in your chats. This app can also be used to export your Telegram data and chats.
Q: Can I translate Telegram?
Telegram is officially available in many languages on most platforms — and we keep adding more.
If you do not like how something in Telegram's interface is translated in your language, or want to help us improve the translation, see our localization platform. Anyone can suggest translations and vote for the best ones, so Telegram localization is run by the community.
If you're looking to go beyond suggestions for individual phrases and would like to help us maintain the official translation to your language on a continuous basis, you can contact @TelegramAuditions. Please include a hashtag with the English name of your language (e.g. #Albanian) and a few links to phrases on this platform with your translation suggestions or comments. Be sure to read the Style Guide carefully before you apply.
Q: Can I help?
Yes, we are always looking for volunteers to help us with user support. If you would be interested in answering questions about Telegram to users from your country, contact our auditions account.

Passport
Telegram Passport is a unified authorization method for services that require personal identification. With Telegram Passport, you can upload your documents once, then instantly share your data with services that require real-world ID (finance, ICOs, etc.).
Your identity documents and personal data will be stored in the Telegram cloud using End-to-End Encryption. To Telegram, this data is just random gibberish, and we have no access to the information you store in your Telegram Passport. When you share data, it goes directly to the recipient.
You can find more information about Telegram Passport on our blog.
If you're a developer or owner of a service that requires real-life ID, kindly take a look at this manual. You can also try requesting Telegram Passport data using this page.
Troubleshooting
Login and SMS
Please make sure you are entering your mobile phone number in the international format.
I.e.: +(country code)(city or carrier code)(your number)
If you are having registration or login problems, please contact us using this form.
Getting a code via a phone call
For security reasons, login codes dictated via a phone call are only available for accounts that have two-step verification enabled (Settings > Privacy & Security > Two-Step Verification).
Please also note that Telegram accounts can only be connected to a mobile number. We currently don't support landline numbers.
Getting a code via Telegram
If you have recently used one of our apps on another device (it could also be a different app on the same device), we may send the login code via Telegram instead of SMS.
To receive such a code, just check Telegram from any of your connected devices. You will find it in the chat with Telegram, a verified profile with a blue check:
Login code sent via Telegram
WARNING! Please note that getting codes via Telegram should not be considered an alternative to using an up-to-date phone number. In case of a change in numbers, always make sure Telegram is connected to a phone number you control, otherwise you risk losing access to your account forever.
Notification problems
If the tips below don't help, check out this detailed guide on Troubleshooting Notification Issues.
ANDROID
Go to Telegram Settings — Notifications and Sounds, make sure that notifications are ON and Importance is set to “High” or greater.
Check whether contact or group is muted.
Make sure Google Play Services are installed on your phone.
Check notification priority for Telegram in Android settings, it can be called Importance or Behaviour depending on your device.
If your phone uses some battery saving software, make sure that Telegram is whitelisted in that application.
NOTE: Huawei and Xiaomi devices have evil task killer services that interfere with the Telegram notification service. For our notifications to work, you need to add Telegram to allowed apps in those devices' security settings. Huawei: Phone Manager App > Protected Apps > Add Telegram to the list. Xiaomi: Services > Security > Permissions > Autostart, find Telegram and enable autostart.
iOS
Go to Telegram Settings — Notifications and Sounds, make sure that notifications are ON in Telegram.
Check that notifications are ON in phone Settings.
Check, whether contact or group is muted.
Shut down Telegram (go to home screen, double tap home button, swipe upwards on Telegram), then go to phone settings, set the alert style for Telegram to NONE. Relaunch Telegram, go to phone settings, set alert style back to banners.
Problems with contacts
If you know your friends have Telegram, but you can't see them — or they appear as numbers instead of names.
Android:
Make sure you are using the latest version of the app.
Relaunch the app (by terminating it from processes list and launching again).
Temporarily change the name of the contact in phone contacts (add a few symbols, then change back again).
If that didn't help, re-login. Remember that logging out kills your Secret Chats.
iOS:
Force quit the app (double tap home button, then swipe up on Telegram), then relaunch and check if it helped.
If that doesn't help, temporarily change the name of the contact in phone contacts (add a few symbols, then change back again).
If that doesn’t work, re-login: Settings > Edit > Log Out. Remember that logging out kills all your Secret Chats. Then log in again.
Deleting contacts on Android
To delete a contact, open a chat with the person, tap the title in the top area of the chat screen to open their profile, then tap on (⋮) in the top right corner > 'Delete contact'.
If you want to delete the contact completely, make sure you also delete them from your phone contacts. Telegram stays in sync and will add the contact back if you don't.
Where did my Secret Chat messages go?
Secret Chats are established between the two devices they were created on. This means that all those messages are not available in the cloud and cannot be accessed on other devices.
Moreover, Secret Chats are also tied to your current login session on the device. If you log out and in again, you will lose all your Secret Chats.
Can't send messages to non-contacts
When users report unwanted messages from a Telegram account, we apply a limit: Reported accounts can only send messages to people who have their number saved as a contact.
This means that if you randomly contact people you don't know and send them annoying messages, you may lose the ability to do so in the future.
If you think that this limit was applied to your account wrongly, please visit this page.
Can't send a message, I am being asked for Stars
Some users charge a small fee — paid in Telegram Stars — for messages from people who are not in their contacts. This is called a Star Message, and it helps people reduce spam in their inbox.
You will see how many Stars are needed before you send the message. If the recipient replies, they may choose to refund the fee.
If you do not want to pay, you can wait for the other person to message you first, or ask them to add you to their contacts.
Telegram uses the camera or microphone in the background!
Telegram can use the microphone in the background if you minimize the app when making a call, recording a video, or recording a voice/video message.
Permission monitors on Samsung and Xiaomi can inadvertently flag and notify you that Telegram requested access to camera in the background. This happens when the app requests info about the camera — it isn’t using the camera. Unfortunately it may look the same to the Samsung and Xiaomi permission monitors.
Camera info is requested by the app when you tap on the attachment button, or start recording a video or a video message. If you do this and quickly close the app, the already initiated request may try to run asynchronously when the app is already in the background, or be sent when the system wakes up the app to show a notification about a new message. In any case, these requests are only for the camera info, the app never uses the camera itself in the background.
Anyone can check Telegram’s open source code and confirm that the app is not doing anything behind their back. We also offer reproducible builds that can help you prove that the version you downloaded from App Store or Google Play is built from the exact same source code we publish.
