Privacy Policy for Sudoku
Effective date: 2026-06-19
This Privacy Policy explains how the Sudoku app (“the App”) handles information when you use it on iOS and Android.
Summary
- The App is designed to work offline.
- We do not require account creation.
- We do not collect personal information from within the App.
- We do not use analytics SDKs, advertising SDKs, or in-app trackers.
- Gameplay and settings data are stored locally on your device.
Information We Collect
We do not collect personal data through the App.
Specifically, the App does not collect or transmit:
- Name, email address, phone number, or mailing address
- Contact lists, photos, camera, microphone, or location
- Health, financial, or biometric information
- Device identifiers for tracking or advertising purposes
- In-app activity for analytics or profiling
Data Stored Locally on Your Device
To provide core gameplay features, the App stores limited game-related data locally on your device:
- Current game session (so you can resume)
- Game history and statistics (for example win rate, streaks, solve times, hints used)
- Recently used puzzle IDs (to reduce immediate repeats)
- App preferences (for example theme, haptic feedback, mistake-limit settings)
This data remains on your device and is not sent to our servers by the App.
Data Deletion
You can delete local game history and statistics from within the App using the reset option in Settings.
If you uninstall the App, locally stored app data may also be removed by your operating system.
Third-Party Services
The App does not include third-party analytics or advertising services.
The App may open external links in your device browser (for example, a developer website). If you visit an external website, that website’s own privacy policy and terms apply.
Children’s Privacy
The App is not directed to children under 13 and does not knowingly collect personal information from children.
International Users
Because the App does not collect personal data through the App, there are no server-side cross-border transfers of personal data by us.
Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Updates will be posted with a revised Effective date.
