1. Introduction
Welcome to Bunson Teacher (“the App”). We respect your privacy. This Policy explains how we collect, use, store, and share information, and the choices you have.
By using the App, you acknowledge this Policy. If you do not agree, please stop using the App.
The App helps users study Chinese (HSK) and IELTS-related vocabulary. Core learning is free; ads may support the free service; sign-in is optional for cloud sync.
2. Information We Collect
2.1 Information you provide or authorize
- Guest mode: You may use the App without signing in. Progress is stored mainly on your device.
- Google Sign-In (optional): If you sign in with Google, we may receive an identifier, display name, email address, and profile photo URL from Google to create/link your account and enable cloud sync.
2.2 Learning and usage data
- Learning progress (e.g. learned words, bookmarks, study days, quiz history);
- In-app preferences (e.g. UI language);
- Technical logs needed to operate the service (e.g. errors, request timing), which may include approximate device type and timestamps. We do not intentionally collect precise GPS location.
2.3 Advertising identifiers (when ads are enabled)
-
The App may use Google AdMob to show ads. Google and its partners may use advertising IDs, IP address, and device/app information for ad delivery, fraud prevention, and measurement.
See Google’s Privacy Policy:
https://policies.google.com/privacy
2.4 What we generally do not collect
- We do not require ID numbers or bank card details for the free + ads product path;
- We do not request contacts, SMS, or precise location for core learning features.
3. How We Use Information
- Provide and improve learning, quizzes, bookmarks, and progress features;
- After sign-in, sync progress to the cloud and restore it after reinstall or device change;
- Show ads (when enabled) to support the free service;
- Security, troubleshooting, and abuse prevention;
- Comply with applicable laws and lawful requests.
4. Storage and International Transfer
- On device: Guest progress is stored primarily on your device.
- Cloud: If you use Google Sign-In and sync, account and progress data may be stored on our cloud servers (e.g. hosted in Asia).
- We use reasonable safeguards, but no method is 100% secure.
5. Sharing
We do not sell your personal information. We may share data only:
- Service providers: e.g. Google (Sign-In, AdMob), hosting providers, under their terms and policies;
- Legal requirements: when required by law, legal process, or authorities;
- Business transfers: in a merger or acquisition, subject to appropriate protections.
6. Retention
- Local data: until you clear app data or uninstall;
- Cloud account/progress: while your account remains active; you may request deletion (below); inactive accounts may be cleaned under operational policies;
- Logs: typically short-term for operations and security.
7. Your Rights and Choices
- Guest use: core learning without signing in;
- Sign-in / sync: optional; signing out stops cloud sync (local data may remain on device);
- Delete local data: via system “clear data” or uninstall;
- Delete cloud data: contact us using the details below (we may verify the request);
- Ads / advertising ID: reset or limit ad tracking in system settings (varies by OS version).
8. Children
The App is for general language learners and is not directed at children under 13 (or a higher age required in your region).
We do not knowingly collect children’s personal information. If you believe we have, please contact us for deletion.
