Dance Clock Privacy Policy
Last updated and effective: September 24, 2026
Dance Clock (the “App”) is made and provided by the developer named on the App’s page in the App Store (“we” or “us”). This policy explains what information the App handles, why, where it’s kept, and how you control it. “Device” means the iPhone or iPad the App is installed on, and “iOS” includes iPadOS.
The short version
• No account needed. We don’t run servers, and we don’t collect your personal information.
• Camera video is analyzed live on your device and is never recorded, saved or uploaded.
• Your alarms, wake-up history, imported sounds and settings stay on your device.
• The only data that might leave your device: a built-in third-party motion recognition component may send usage statistics that contain no video (see section 3). If you don’t want that, turn off the App’s camera access.
1. Information the App handles
Camera video
• Why: when your alarm rings, you do a mission (like dancing) in front of the front camera. The App spots body keypoints, such as where your shoulders, elbows and knees are, to count your moves and time your mission.
• How: frames are analyzed in memory one by one and thrown away right after. The App doesn’t record video, take photos, write frames to storage, or upload anything. Keypoints are only used while the mission is running and are never saved.
• The camera only turns on when you start a mission or a practice run.
Alarms and wake-up history
• Alarms: time, repeat days or date, name, mission and difficulty, sound and wake-up check settings.
• Wake-up history: when each alarm rang, when you finished the mission, which mission it was, and whether you used the backup.
• Why: to ring on time and to show your streak and history.
• Where: only in the App’s storage on your device.
Sounds you import or record
• When you import audio or video from Files, or pick a video from Photos, the App keeps only the audio: the part you choose (up to 30 seconds) is converted and copied into the App’s storage so your alarm can play it. Video images aren’t saved. Videos are picked with the system photo picker, so the App only gets the one video you choose, never your whole library.
• When you use Record, the App records up to 30 seconds through the microphone, and only after you tap the record button.
• These files stay on your device and are never uploaded. Delete them anytime: touch and hold one under My Sounds.
Purchases and subscriptions
• When you buy Pro (yearly or weekly subscription, or lifetime), Apple handles payment through your Apple Account. We never see your card or Apple Account details.
• The App reads Apple’s purchase receipts on your device only, to check whether you have Pro, when a subscription ends and whether it renews, so it can remind you the day before and pause alarms after it ends. Receipts are never uploaded.
Settings
• Preferences like your default mission and sound, reminders, weekly freezes and App icon are stored on your device.
2. System permissions
• Camera (required): for the motion recognition above. Without it you can’t do missions, but you can still stop an alarm with the backup (hold a button), which doesn’t count toward your streak.
• Alarms (iOS 26 and later, required): sets system alarms so they ring on Silent, in a Focus and on the Lock Screen. iOS triggers the alarms.
• Notifications (recommended; used for alarms before iOS 26): bedtime reminders, streak reminders, alarm problem alerts and subscription reminders. Before iOS 26, alarms also arrive as notifications. All notifications are created on your device, not on a server.
• Microphone (optional): only for recording a custom sound. Everything else works without it.
Each permission is only requested after you tap the related button. Change them anytime in Settings → Dance Clock.
3. The motion recognition component
The App uses a component from a third party to recognize body poses on your device. Camera frames are processed on your device only and are never sent to anyone. According to its documentation, the component may send statistics about how it runs to its provider. We found no code that sends such statistics in the version the App uses, but until that’s confirmed by testing on a real device, we’re telling you it’s possible:
• What might be sent: the App’s identifier and version, the system version, and technical data such as whether recognition is running, how long it takes and any errors. As with any network request, the receiving server also sees your IP address.
• What is never sent: camera video, photos, body keypoints, your alarms or your wake-up history.
• Who receives it and where: the component’s provider; the data may be processed and stored outside your country. Contact us if you want the recipient’s name, contact details and processing rules, and we’ll tell you.
• How to stop it: turn off camera access in Settings → Dance Clock. The App then won’t open the camera, and the component won’t analyze anything. You can still stop alarms with the backup, which doesn’t count toward your streak.
Apart from this component, the App has no advertising, analytics, crash reporting, social login or third-party payment services (purchases use Apple’s In-App Purchase).
4. When you email us
• Tapping Contact Us, Suggest a Feature or “Still not ringing? Contact Us” opens your mail app with some technical details already filled in: device model, system version, App version, language and region, alarm type, number of alarms, permission status, and whether you have Pro. They help us pin down your problem fast. You can read, edit or delete them before sending, and we only receive them if you hit send.
• We receive your email address, your message and anything you attach. We only use it to reply and fix your problem, and we delete the emails within 6 months after your issue is resolved, unless the law requires otherwise.
5. What we don’t do
• No ads, no tracking across apps or websites, and no reading your advertising identifier (IDFA).
• We don’t sell, rent or trade any data.
• We don’t ask for your phone number, email, name, location, contacts, photo library or health data, and we don’t use the microphone unless you record a sound.
• No accounts and no cloud sync.
6. Retention and deletion
• Everything stays on your device until you delete it: delete single alarms or imported sounds, or delete the App to remove all its data.
• iOS manages system alarms. Before deleting the App, turn off all alarms in the App: Settings tab → Alarm Settings → Turn Off All Alarms so none ring afterwards.
• If you use iCloud Backup or back up your device to a computer, backups may include the App’s data. Apple handles that under its privacy policy, and you can manage it in your backup settings.
• We don’t store data about you, so there’s nothing on a server for us to delete. Any statistics the motion recognition component may send are kept by its provider under its own policy; contact us and we’ll help you reach them.
7. Security
The App’s data lives in the storage iOS gives each app, which other apps can’t read, and iOS encrypts it when your device has a passcode. With no accounts or servers, your alarms, history and sounds never travel over the internet. If a security incident could affect you, we’ll let you know in the App or another reasonable way, as the law requires.
8. Your rights
You can view and change all alarms and settings, delete alarms, sounds or the whole App (your history goes with it), and turn off camera, alarm and notification access in Settings at any time. Turning a permission off doesn’t affect what happened before. Depending on where you live (for example, in the EEA or UK), you may have rights to access, correct or delete personal data and to complain to your local data protection authority. Questions? Contact us below; we reply within 15 business days.
9. Children
The App isn’t directed at children under 13 (or the minimum age in your country). Younger users should use it with a parent or guardian’s permission. We don’t knowingly collect personal information from children.
10. Changes
We may update this policy when the App changes. We’ll change the date at the top, and point out big changes in the App.

跳舞闹钟隐私政策
更新日期：2026 年 9 月 24 日 生效日期：2026 年 9 月 24 日
「跳舞闹钟」（下称“本 App”）由 App Store 中本 App 产品页上列明的开发者（下称“我们”）开发和提供。本政策说明本 App 会处理哪些信息、为什么处理、保存在哪里，以及你怎样控制这些信息。本文中的“设备”指安装本 App 的 iPhone 或 iPad；“iOS”也包括 iPad 上的 iPadOS。
一句话概括
• 本 App 不需要注册账号，我们没有自己的服务器，也不收集你的个人信息。
• 相机画面只在你的设备上实时分析，不录像、不保存、不上传。
• 闹钟、起床记录、导入的声音和各项设置只保存在你的设备上。
• 唯一可能离开设备的数据：本 App 内置的第三方动作识别组件，可能会发送不含画面的运行统计（见第三节）。如果你不同意，可以关闭本 App 的相机权限。
一、本 App 处理的信息
1. 相机画面
• 用途：闹钟响后，你需要在前置相机前完成跳舞等动作任务，本 App 通过画面识别身体关键点（如肩、肘、膝的位置）来判断动作是否完成、计数和计时。
• 处理方式：画面在设备内存中逐帧分析，分析完立即丢弃。本 App 不录像、不拍照、不把画面写入存储，也不上传到任何服务器。识别得到的关键点坐标只在任务进行中临时使用，不会保存。
• 只有在你开始动作任务或试跳时才会打开相机。
2. 闹钟和起床记录
• 闹钟：时间、重复的星期或日期、名称、选择的任务和难度、铃声、起床确认等设置。
• 起床记录：每次闹钟响起的时间、完成任务的时间、任务类型，以及是否使用了备用任务。
• 用途：按时响铃、显示连续起床天数（连胜）和起床历史。
• 保存位置：只保存在本 App 在你设备上的存储空间内。
3. 你导入或录制的声音
• 当你从「文件」导入音频或视频、或从相册选择视频作为铃声时，本 App 只提取其中的声音，把你选中的一段（最长 30 秒）转换格式后复制到本 App 的存储空间，供闹钟播放。视频画面不会被保存。从相册选视频使用系统的照片选择器，本 App 只能拿到你选中的那一个视频，无法访问你的整个相册。
• 当你使用「录一段」时，本 App 通过麦克风录制最长 30 秒的声音，保存为铃声。只在你点按录音按钮后才会录音。
• 这些文件只保存在你的设备上，不会上传，你可以随时在铃声页面长按删除。
4. 购买与订阅
• 购买 Pro（按年订阅、按周订阅或终身买断）时，付款由 Apple 通过你的 Apple 账户处理，我们收不到你的银行卡、Apple 账户等支付信息。
• 本 App 只在你的设备上读取 Apple 提供的购买凭证，用来判断你是否有 Pro、订阅何时到期、是否会自动续费，并据此在到期前一天提醒你、在到期后暂停闹钟。这些凭证不会上传，我们没有自己的服务器。
5. 设置
• 默认任务、默认铃声、提醒开关、每周冻结次数、App 图标等偏好设置，保存在设备上。
二、本 App 使用的系统权限
• 相机（必需）：用于上面所说的动作识别。拒绝后无法完成动作任务，但仍可用备用任务（按住按钮）关掉闹钟，备用任务不计入连胜。
• 闹钟（iOS 26 及以上，必需）：通过系统闹钟功能设置闹钟，使闹钟在静音、专注模式和锁屏时也能响。闹钟由 iOS 系统负责触发。
• 通知（建议；iOS 26 以前的系统上用来响闹钟）：用于睡前提醒、连胜提醒、闹钟异常提醒和订阅到期前的提醒；在 iOS 26 以前的系统上，闹钟也通过通知提醒。所有通知都在设备本地生成，不经过任何服务器。
• 麦克风（可选）：只用于「录一段」自定义铃声。不开启不影响其他功能。
每项权限都只在你点按相关按钮后才会请求。你可以随时在 iOS「设置」→「跳舞闹钟」里关闭。
三、动作识别组件
本 App 使用一个由第三方提供的组件，在设备上识别身体姿势。输入的画面只在设备上处理，不会发送给任何人。按照该组件的说明，它可能向其提供方发送关于自身运行情况的统计数据。我们在本 App 使用的版本中没有发现发送这类统计的程序代码，但在经过实测确认之前，我们如实告知这一可能：
• 可能发送的内容：本 App 的标识和版本、系统版本，以及识别功能的运行状态、耗时和错误等技术数据。与任何网络请求一样，接收方的服务器也会看到你的网络 IP 地址。
• 不发送的内容：相机画面、照片、视频、身体关键点坐标、你的闹钟和起床记录。
• 接收方与处理地点：该组件的提供方；数据可能在中国境外处理和存储。如需了解接收方的名称、联系方式和处理规则，可以通过本政策末尾的方式联系我们，我们会如实告知。
• 如何停止：在 iOS「设置」→「跳舞闹钟」里关闭相机权限。关闭后动作任务不会打开相机，该组件不会分析任何画面；闹钟可以改用备用任务（按住按钮）关掉，备用任务不计入连胜。
除上述组件外，本 App 没有接入任何广告、统计、崩溃分析、社交登录或第三方支付服务（购买使用 Apple 自己的 App 内购买）。
四、你通过邮件联系我们时
• 在本 App 里点「联系我们」「提个功能建议」或「还是不响？联系我们」时，会打开你设备上的邮件 App，并预先填好一段技术信息：设备型号、系统版本、App 版本、语言和地区、闹钟方式、闹钟数量、权限状态，以及是否为 Pro。这段信息用来尽快定位你遇到的问题，发送前你可以查看、修改或删除；只有你点了发送，我们才会收到。
• 我们会收到你的邮箱地址、邮件内容，以及你自己附上的信息。这些信息只用于回复和解决你的问题，不用于其他目的；问题处理完毕后我们会在 6 个月内删除相关邮件，法律法规另有要求的除外。
五、我们不做的事
• 不做广告，不跨 App 或网站追踪你，不读取广告标识符（IDFA）。
• 不出售、出租或交换任何数据。
• 不要求提供手机号、邮箱、姓名、位置、通讯录、照片库或健康数据；除你主动录制铃声外，不使用麦克风。
• 没有账号系统，也没有云同步。
六、保存期限与删除
• 本 App 的所有数据都保存在你的设备上，直到你删除它们：你可以删除单个闹钟、删除导入的声音；删除本 App 会同时删除它在设备上保存的全部数据。
• 系统闹钟由 iOS 管理。删除本 App 前，建议先在「设置 → 闹钟设置 → 关闭全部闹钟」关掉闹钟，以免删除后仍有已设置的闹钟响起。
• 如果你开启了 iCloud 云备份或用电脑备份设备，备份中可能包含本 App 的数据，这部分由 Apple 按照其隐私政策处理，你可以在 iOS 的备份设置中管理。
• 我们自己不保存任何关于你的数据，因此无法也不需要为你删除服务器上的数据。动作识别组件可能发送的统计数据由其提供方按其政策保存；如需就这部分数据行使权利，可以联系我们，我们会协助你联系提供方。
七、信息安全
本 App 的数据保存在 iOS 为每个 App 单独划分的存储空间里，其他 App 无法读取；在设备设置了锁屏密码时，iOS 会对这些数据加密。因为本 App 没有账号和服务器，你的闹钟、起床记录和声音文件不会经过网络传输。如果发生可能影响你的安全事件，我们会按法律要求通过 App 内提示或其他合理方式告知你。
八、你的权利
你可以随时：查看和修改所有闹钟与设置；删除闹钟、导入的声音或整个 App（起床记录会随 App 一起删除）；在 iOS 设置中撤回相机、闹钟、通知权限（关闭相机权限后，动作识别组件就不会分析任何画面）。撤回权限不影响撤回前基于权限进行的处理。如有任何问题，可以通过下方方式联系我们，我们会在 15 个工作日内答复。
九、未成年人
本 App 不面向 14 周岁以下的儿童。如果你是未满 14 周岁的未成年人，请在监护人的陪同和同意下使用。本 App 不会有意收集未成年人的个人信息。
十、政策更新
本 App 的功能变化可能导致本政策更新。更新后我们会修改本页顶部的日期，涉及重大变化时会在 App 内显著提示。
