Privacy Policy

Math Games: Brain Training helps you practice fractions and percentages. This policy describes the learning records and optional learner photo saved by the app, plus information used by its support and document pages.

Effective date: September 24, 2026

Learning records on your device

The app saves your onboarding completion, selected difficulty, haptics preference, unfinished practice session, submitted answers, results, stars, practice dates, topic accuracy and exercise types marked for review. These records let you resume practice and see your progress.

Learning records are stored locally on your device. The app has no account system, cloud synchronization or server for receiving those records. Practice questions are prepared and checked on the device, and practice works offline.

Optional learner photo

In Settings, you can take a photo with the camera or choose one from your photo library. The photo you select appears as your learner avatar in the app. The app saves a copy in its local storage and stores its file name so the avatar appears when you return. It does not attach the photo to support messages or make it visible to other app users.

You can change or remove the avatar in Settings. Removing it clears the saved selection and attempts to delete the app's local copy. If file deletion fails, a copy may remain in local app storage until that storage is removed. If you chose a photo from your library, removing the avatar does not delete the original.

Advertising, analytics and permissions

The app does not include advertising, analytics, tracking or purchases. It does not request access to your contacts, location or microphone. Camera and photo selection are optional and used only when you choose Take Photo or Choose from Library in Settings. iOS may request access or show its photo picker for those actions.

Local storage and removal

Learning records remain in the app's local storage until that storage is removed. Deleting the app through iOS removes its local app data; offloading an app may retain its data. Device backups and restoration are controlled by your iOS settings and may include learning records and the avatar photo.

If saved records cannot be read, the app offers Retry and an explicit Start Fresh confirmation. Start Fresh replaces local progress with an empty state.

Support messages

The Support Form is for app issues, questions and feedback and does not require an account or sign-in. When you send a message, its topic and text are stored online, together with any name or email address you choose to provide. The form also records the support page address, browser and device information supplied by your browser, submission time and a request status.

This information is used to review messages, understand reported issues and manage support. The app does not automatically attach learning records to a request. Please do not include passwords, payment details, sensitive personal information or information about other people.

Messages are stored for later review. Providing contact details is optional and does not guarantee a reply. Support records remain in the support system until removed by its operator; there is no automatic deletion schedule. Removing the app does not remove messages already submitted online.

Hosted pages and service access

Opening these pages or sending a message transmits ordinary connection information, such as an IP address and browser details, to the services that host the pages and store support requests. Those services process information to deliver and secure them. These pages do not include advertising or analytics scripts and do not set advertising or analytics cookies.

Support requests are not publicly readable. Access is restricted to authorized project administrators and service providers operating the support system. Information may also be disclosed when required by law. We do not sell personal information or use support messages for advertising.

Children's privacy

The app is intended only for adults aged 18 or older. Anyone under 18 must not use the app or submit information.

Questions and changes

For app issues, questions or feedback, use the Support Form. This page may be updated when the app's data handling changes. The effective date above identifies the current version.
