Sudoku Privacy Policy

Last updated: 2026-04-21

Sudoku (“the App”) is a single-player Sudoku puzzle game. This policy explains what information the App handles. In short: nothing leaves your device.

1. Information We Collect

None. Sudoku does not collect, transmit, or share any personal information. The App has no user accounts, no analytics, no advertising SDKs, and no network requests.

2. Information Stored Locally on Your Device

To remember your progress, the App saves the following on your device using Android’s local storage:

• Current puzzle state and completion progress
• Best completion times per difficulty
• Your sound and haptics preferences

This data never leaves your device. It is removed when you uninstall the App or use the in-app reset option where provided.

3. Permissions

The App requests only the minimum permissions required to run (vibration for haptic feedback). It does not access your contacts, camera, microphone, location, photos, or files.

4. Third-Party Services

None. The App does not integrate any third-party SDKs or analytics tools.

5. Children’s Privacy

Sudoku is safe for all ages. Because the App does not collect any data, it does not knowingly collect information from children under 13.

6. Changes to This Policy

If this policy changes, the “Last updated” date above will be revised. Continued use of the App after changes means you accept the updated policy.
