Math Hero Kids · last updated

1. Summary

Math Hero Kids (“the app”) is a free offline math learning game for children, published by Cool App Helpdesk.

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

4. Permissions used

PermissionReason
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.
