Brain Trainer Privacy Policy

Kumudan Softwares built Brain Trainer as a math practice and focus game with quick rounds, daily challenges, local leaderboards, settings, and progress tracking. This policy explains what data the app stores, how it is used, and how you can remove it.

Last updated: June 6, 2026 No account required Local-first game data Package: in.kumudan.braintrainer

1. Information We Collect

Brain Trainer does not require you to create an account or sign in. The current app stores gameplay and settings data on your device.

A. Data stored on your device

  • Display name used inside the app.
  • Total sessions played, questions answered, coins, and local profile state.
  • Game session results, including mode, difficulty, score, accuracy, streak, round duration, and timestamp.
  • High scores for game modes and difficulty levels.
  • Daily challenge progress and the date of the last daily challenge played.
  • Settings such as enabled operators, difficulty, round duration, sound, haptics, theme pack, and onboarding status.

B. Support contact

If you contact us by email, we receive the information you choose to send, such as your email address, message, screenshots, or device details you include.

2. How We Use Information

We use app data to provide the Brain Trainer experience.

  • Save your settings between app launches.
  • Show your local profile, progress, high scores, and leaderboard-style results on the device.
  • Resume or clear daily challenge progress.
  • Adjust math practice rounds based on your selected operators, difficulty, and duration.
  • Respond to support requests that you send to us.

Current service note

The current app source does not include Firebase, Google AdMob, Google Analytics, account login, cloud sync, or online leaderboard integrations. The Android manifest includes internet permission, but the current build stores game data locally.

3. Data Sharing

We do not sell your personal information.

  • Local gameplay data stays on your device unless you back up, transfer, export, or share device data through Android or Google device settings.
  • We do not run our own Brain Trainer server for accounts, cloud leaderboards, or profile sync in the current version.
  • We may disclose information if required by law or a valid legal request.

4. Data Retention

Brain Trainer keeps local data until you remove it.

  • You can clear local high scores from the app settings where supported.
  • You can clear app storage from Android settings to remove local app data.
  • Uninstalling the app removes locally stored app data from your device.
  • Android or Google device backup may keep or restore some app data depending on your device settings.

5. Device Permissions

The current Android manifest requests internet permission. Brain Trainer does not request sensitive permissions such as location, contacts, camera, microphone, SMS, or phone call access in the current build.

6. Security

Brain Trainer uses Android local storage mechanisms, including Room database storage and DataStore preferences, for game progress and settings. No storage method is perfectly secure, so we cannot guarantee absolute protection.

7. Your Choices

  • You can edit your display name and app preferences inside the app.
  • You can clear local high scores where supported by the app.
  • You can clear app storage or uninstall Brain Trainer to remove local data from the device.
  • You can contact us if you have privacy questions or support-related deletion requests.

8. Children's Privacy

Brain Trainer is a general math practice game and is not specifically directed to children under 13. We do not knowingly collect personal information from children through our own servers.

9. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the last updated date above.
