1. Summary
Math Hero Kids (“the app”) is a free offline math learning game for children, published by Cool App Helpdesk.
- The app collects no personal data and operates no servers.
- The app does not request the
INTERNETpermission and makes no network connections. - The app contains no advertising, no analytics, and no third-party tracking SDKs.
2. Data we collect
None. The developer does not collect personal data, telemetry, identifiers, device information, IP addresses, advertising IDs, or usage analytics. There are no user accounts and the developer operates no servers that the app communicates with.
3. Data stored on your device
| Item | Where | Sent off device? |
|---|---|---|
| Game progress, scores, completed levels | App-private Room database | Never |
| App settings and preferences | App-private DataStore | Never |
4. Permissions used
| Permission | Reason |
|---|---|
POST_NOTIFICATIONS (Android 13+) | Show optional in-app reminders. Revocable at any time in system settings. |
The app does not request INTERNET, location, contacts, storage, microphone, camera, phone state, or any other sensitive permission.
5. Network activity and third parties
The app does not request the INTERNET permission, so the operating system prevents it from making any network connection. The app contains no advertising SDKs, no analytics SDKs, no crash-reporting SDKs, and no social or attribution SDKs.
6. Children’s privacy
Math Hero Kids is designed for children. We comply with the Children’s Online Privacy Protection Act (COPPA) and the GDPR’s provisions for children by the simplest means available: we collect no personal information from anyone, including children. There is no profile, no account, no chat, no in-app purchases, and no advertising.
7. Data retention and deletion
Game progress and settings remain on your device until you reset them inside the app, clear the app’s storage in Android Settings → Apps → Math Hero Kids → Storage, or uninstall the app.
8. Security
The app holds no personal data and makes no network requests, so the privacy attack surface is essentially zero. App data is held in the app’s private storage, protected by Android’s built-in application sandboxing. The app is distributed through the Google Play Store, which verifies the developer signing key on every update.
9. Changes to this policy
If any material aspect of how the app handles data ever changes, this page will be updated and the “last updated” date above will be bumped. Continued use after a change constitutes acceptance.
