Information stored by the app

Mistake Coach may store the following study information:

• Question images captured with the camera or selected from the library
• Subjects, topics, and mistake reasons
• Optional notes entered by the user
• Review schedules and review results
• Free-practice activity
• Progress information and statistics
• Language, theme, and reminder preferences

This information is stored locally in the app’s private storage on your device. Mistake Coach does not require a user account.

Camera and photo access

Camera access is requested only when you choose to photograph a question. Photo-library access is requested only when you choose an existing question image.

Selected images are copied into the app’s private local storage. Mistake Coach does not upload these images to a server.

Notifications

If you enable the optional daily review reminder, Mistake Coach requests notification permission and schedules a local notification on your device.

Reminder settings are stored locally. The current version does not use remote push notifications.

Data collection and sharing

The current version of Mistake Coach does not transmit your study records, question images, review history, or app preferences to Delta Web Sistem or third parties.

The current version does not contain advertising or user-analytics services. Delta Web Sistem does not sell personal information.

Your device operating system and app-distribution platform may process technical information under their own terms when you download, install, or update the app.

Data retention and deletion

Information remains on your device until you delete it, clear the app’s storage, or uninstall Mistake Coach.

Deleted mistakes can be restored from Recently Deleted until you choose Delete Forever.

Permanent deletion removes the related local question image and review history. Clearing app storage or uninstalling the app may remove all locally stored Mistake Coach information.

Because the current version does not provide user accounts, there is no server-side account or associated cloud data to delete.

Security

Mistake Coach uses the private application storage provided by your device operating system. You are responsible for protecting access to your device. No storage method can be guaranteed to be completely secure.

Children’s privacy

Mistake Coach is a general study tool. The app does not knowingly transmit personal information from children or other users to Delta Web Sistem.

Parents and legal guardians should supervise device and application use where appropriate.

Changes to this policy

This policy may be updated if Mistake Coach’s features or data practices change. The effective date will be updated when changes are made.
