Mathdoku - Privacy Policy

1. Information We Collect

The App does not require an account, does not ask for any personal information and does not request any device permissions.

All game data is stored locally on your device and never leaves it. This includes:

• The game in progress (puzzle, entries, notes, hints used, score and elapsed time)
• Your progress for each level (best score, best time, number of wins and date of the first completion)
• Your preferences (theme, language and haptic feedback) and whether the tutorial has been shown

1.1 Diagnostics and Analytics

To keep the App stable we use two third-party services in production builds:

• Sentry collects crash reports, error diagnostics and related technical logs (device model, operating system version, app version and the technical details of the error). The App is configured not to send personally identifiable information.
• Vexo Analytics collects anonymous usage statistics (such as which screens are opened and for how long) so we can understand how the App is used.

These services may process the data on their own infrastructure. Please refer to their privacy policies for details: Sentry Privacy Policy and Vexo Privacy Policy.

1.2 App Updates

The App checks Expo (EAS Update) servers for updates when it starts. This request contains technical information needed to deliver the right update, such as the app version, runtime version and platform. It does not include your game data.

2. Data Sharing

We do not sell, rent or share your data with anyone beyond the service providers listed above.

3. Children

The App does not knowingly collect any personal information from anyone, including children.

4. Deleting Your Data

Uninstalling the App removes all locally stored game data, progress and preferences.

5. Changes to This Policy

We may update this policy from time to time. The latest version is always available at the address linked from the App's Settings screen.
