AOWO is developed and published by KNIGHT SPACE TECHNOLOGY LIMITED ("KNIGHT SPACE", "we", "us" or "our"). This Privacy Policy explains how we collect, use, share, retain and protect information when you use the AOWO mobile application and related services (the "Service").
AOWO is an anonymous social app. You can throw and pick up drift bottles, share moments, comment, chat one-to-one, and use optional nearby matching features. You do not need to provide your real name, email address or phone number to use the core Service.
This Privacy Policy applies to the AOWO app (package name com.knightspaceapp.bottledmessage.app1025), our website and any related features that link to this policy. It does not apply to third-party websites, apps or advertising destinations that we do not control.
We collect the following categories of information.
Profile information: nickname, gender, birth year, city or region, bio/signature and avatar.
Bottle content: text, photos, videos, voice recordings and other media you choose to send in a bottle.
Moments and comments: posts, images, videos, comments, replies, likes and reports.
Chat content: messages, photos, videos, voice recordings and other content you send in a one-to-one chat.
Safety and support information: reports you submit, block lists, moderation records and messages you send to our support team.
Please do not include sensitive information (such as health, financial, government ID or precise home address information) in bottles, moments or chats. Content you share with other users may be seen, copied or screenshotted by them.
Anonymous identifiers: an app-scoped installation identifier and/or the Android Advertising ID (AD ID), where permitted by your device settings.
Device and app information: device model, manufacturer, operating system version, language, screen information, app version, network type and crash/diagnostic data.
Approximate location: city or country level location inferred from your IP address. We do not request precise GPS location for the core features of AOWO.
Usage information: bottles thrown or picked, moments viewed, comments, likes, chat activity, feature interactions, session times and similar in-app events.
Advertising information: ad requests, impressions, clicks, ad format, mediation/ad network responses and related performance data, when advertising is enabled.
If you use a third-party sign-in, advertising, analytics or mediation service, that provider may share limited information with us, such as an app-scoped identifier, consent status or ad performance data. The information a provider shares depends on its configuration, your consent choices and its own privacy policy.
We use information for the following purposes:
Provide the Service: create and maintain your anonymous profile, deliver bottles and moments, enable comments, chats, notifications and nearby matching.
Personalize your experience: show relevant content, remember your preferences and display your profile and content to other users as you choose.
Safety and moderation: review content, detect prohibited or harmful material, enforce our rules, process reports and block lists, prevent spam, fraud and abuse, and protect users.
Advertising: serve, measure and improve ads, including personalized and non-personalized ads, subject to your consent and device settings.
Analytics and improvement: understand how the Service is used, diagnose crashes, test features, measure performance and improve the app.
Customer support: respond to your questions, requests and privacy rights requests.
Legal and compliance: comply with applicable laws, respond to lawful requests, enforce our terms and protect our rights, users and the public.
Business operations: operate, transfer or reorganize the Service as part of a merger, acquisition, financing or asset sale, subject to this policy.
Where the GDPR, UK GDPR or Swiss data protection law applies, we rely on:
Contract: to provide the Service you request, including your profile, bottles, moments and chats.
Consent: for personalized advertising, certain analytics, marketing communications and other processing where consent is required. You may withdraw consent at any time.
Legitimate interests: to operate, secure and improve the Service, prevent abuse, moderate content and protect users, where those interests are not overridden by your rights.
Legal obligation: to comply with applicable law and lawful requests.
AOWO may display advertising and use analytics and mediation services. When these services are enabled, the providers listed below may collect or receive information such as device identifiers (including the Android Advertising ID), IP address and approximate location derived from it, device and app information, app activity, ad interactions, diagnostics and performance data. The exact data collected depends on the provider, SDK version, your region, your consent choices and the ad format.

These partners may act as independent data controllers for their own advertising and analytics activities. We encourage you to review their privacy policies. We do not control their independent processing.
In the EEA, UK and Switzerland, we will request consent for personalized advertising and related processing where required, using a consent management platform. You can decline personalized advertising; you should still be able to use the Service, and you may see non-personalized ads.
You can withdraw or change consent through the privacy settings made available in the app, through the consent message shown by our consent platform, or by contacting us.
You can reset or delete your Android Advertising ID, and manage ad personalization, in your device settings (for example, Settings → Google → Ads on many Android devices).
You can learn more about interest-based advertising and opt-out choices at https://www.aboutads.info/choices/ and https://www.youronlinechoices.eu/ where available.
If advertising is not available in your region or you have opted out, some ad-related data collection may be reduced, but the Service may still use limited technical data to deliver non-personalized ads and prevent fraud.
We may use Google Firebase Analytics and provider SDKs to understand usage, measure performance and diagnose problems. Analytics data may include app events, device and app information, approximate location derived from IP, and identifiers. We use this information in aggregated or de-identified form where practicable.
Our website may use cookies and similar technologies for essential functionality, preferences, analytics and advertising. You can control cookies through your browser settings. Blocking certain cookies may affect website functionality. The app itself uses SDK-based identifiers and local storage rather than browser cookies for most functionality.
We do not sell your personal information for money. We may share information in the following circumstances:
With other users: your nickname, avatar, bio, bottles, moments, comments and chat messages are shared with the users you interact with or who can view that content. Content you post publicly may be seen by a wider audience.
With service providers: hosting, database, storage, media processing, moderation, analytics, advertising, mediation, customer support, security and fraud-prevention providers that process information on our behalf or as independent controllers.
With advertising and analytics partners: as described in Section 3, subject to your consent and settings.
For safety and legal reasons: to comply with law or valid legal process; to investigate fraud, abuse or security incidents; to enforce our terms; to protect the rights, property or safety of KNIGHT SPACE, our users or the public; or to respond to a government request where required.
For business transfers: in connection with a merger, acquisition, financing, reorganization, bankruptcy or sale of assets, subject to appropriate confidentiality and notice requirements.
With your direction or consent: when you ask us to share information or otherwise consent.
We may also share aggregated or de-identified information that cannot reasonably be used to identify you.
We do not sell personal information for monetary consideration. Certain uses of advertising identifiers and apparent sharing with advertising partners for cross-context behavioral advertising may be considered "sharing" or a "sale" under the CCPA/CPRA. You can opt out by contacting us at the email below and by using the ad and privacy controls described in Section 3.2. We will not discriminate against you for exercising your privacy rights.
We retain information only for as long as necessary for the purposes described in this policy, including to provide the Service, maintain safety and moderation records, resolve disputes, enforce agreements and comply with law.
Profile and content: retained while your account is active and until you delete the content or your account, subject to moderation and legal retention.
Inactive accounts: if you do not log in or use the Service for 90 consecutive days, we may delete or de-identify your profile, content and associated identifiers, unless we need to retain them for safety, fraud prevention, dispute resolution or legal compliance.
Chats: deleted from the active Service when a conversation is deleted by the participants or when required for safety and legal reasons. Backup copies may persist for a limited period before being overwritten.
Reports and moderation records: retained as necessary to investigate reports, enforce blocks and bans, prevent re-offending and comply with law.
Logs and diagnostics: retained for a shorter period, unless needed for security, fraud prevention or legal compliance.
Advertising and analytics data: retained according to the provider's own retention practices and your consent choices.
If you request deletion, we will delete or de-identify your information within the time required by applicable law, except for information we must retain for legal, security or fraud-prevention reasons. Residual copies may remain in backups for a limited period.
We use administrative, technical and organizational measures designed to protect information, including encryption in transit using HTTPS/TLS, access controls, retention limits and moderation controls. However, no method of transmission over the Internet or method of electronic storage is completely secure. We cannot guarantee absolute security, and you share content with other users at your own risk.
If we become aware of a security incident affecting your information, we will notify you and the relevant authorities as required by applicable law.
We may process and store information in countries other than your own. Those countries may have data protection laws that differ from the laws in your jurisdiction. Where required, we use appropriate safeguards for international transfers, such as standard contractual clauses, the UK International Data Transfer Addendum or other lawful transfer mechanisms. You can contact us for more information about the safeguards we use.
Depending on where you live, you may have some or all of the following rights:
Access: request a copy of the personal information we hold about you.
Correction: request that inaccurate information be corrected.
Deletion: request deletion of your information.
Portability: request a portable copy of certain information you provided.
Restriction: request that we restrict certain processing.
Objection: object to processing based on legitimate interests.
Withdraw consent: withdraw consent at any time for processing based on consent, including personalized advertising, without affecting processing that already occurred.
Opt out of sale/sharing: opt out of certain advertising-related sharing as described in Section 4.1.
Non-discrimination: we will not deny you the Service, charge you different prices or provide a different level of service because you exercised your privacy rights, except as permitted by law.
Complaint: lodge a complaint with your local data protection authority. In the EEA, you can contact the supervisory authority in your country of residence or work. In the UK, you can contact the Information Commissioner's Office.
To exercise your rights, email us at zhaoleyang1994@gmail.com. We may need to verify your request, for example by asking you to confirm your anonymous identifier or other information associated with your use of the Service. Authorized agents may submit requests where permitted by law.
If you are a California resident, you may have the right to know, access, correct, delete, opt out of sale/sharing and limit the use of sensitive personal information, and to not be discriminated against. We do not collect precise geolocation, government identifiers, financial account information or health information for the core Service. We may collect identifiers, commercial information (ad interactions), internet or other network activity, approximate geolocation, audio/visual information and inferences as described above. To exercise your rights, contact us at the email above.
Residents of other U.S. states with comprehensive privacy laws may have similar rights. We will honor requests as required by applicable law.
Because the Service is a mobile app, browser "Do Not Track" signals generally do not apply. Where required, our website will recognize Global Privacy Control signals as an opt-out of sale/sharing for browser-based activity.
You can delete certain content in the app (for example, bottles, moments, comments or chats) using the available delete controls. You can delete all of your data through Settings → Delete My Data in the app, or by emailing us at zhaoleyang1994@gmail.com.
When you delete your account or data, we will delete or de-identify your profile, bottles, moments, comments, chats and related media, except where we need to retain information for legal, safety, fraud-prevention or moderation purposes. Deleting the app does not automatically delete your account or content; you must use the in-app deletion control or contact us.
The Service is not directed to children. AOWO involves anonymous interactions with strangers, user-generated content and advertising, and is intended for users aged 18 and over. We do not knowingly collect personal information from anyone under 18. If you are a parent or guardian and believe that a child under 18 has provided us with personal information, contact us and we will take appropriate steps to delete it. If we learn that we have collected information from a child under 18, we will delete it as required by law.
The Service may contain links to third-party websites, apps or advertisements. We are not responsible for the privacy practices or content of those third parties. This Privacy Policy does not apply to them. We encourage you to review their privacy policies before providing information or interacting with their services.
We may update this Privacy Policy from time to time. When we make material changes, we will post the updated policy in the app or on our website and update the "Last updated" date. Where required by law, we will provide additional notice or obtain consent. Your continued use of the Service after the effective date of an updated policy means you accept the updated policy.
If you have questions about this Privacy Policy, want to exercise your privacy rights, or have a privacy concern, contact:
Developer: KNIGHT SPACE TECHNOLOGY LIMITED
Email: zhaoleyang1994@gmail.com
App: AOWO (com.knightspaceapp.bottledmessage.app1025)
