Introduction
Welcome to Sudoku. We respect your privacy and are committed to protecting any information that may be associated with your use of our app. This Privacy Policy explains how we handle your data.
Information We Collect
Sudoku itself does not collect personal information such as your name, email address, or account details. Game data is stored locally on your device and is never transmitted to our servers.
Data stored locally on your device includes:
- Game progress and saved games
- Your preferences (sound, haptics, display settings)
- Game statistics (best times, streaks, completed puzzles)
- Subscription status
Advertising (Free Version Only)
The free version of Sudoku displays advertisements provided by Google AdMob. To serve ads, AdMob may collect and process certain data, including:
- Device identifiers (such as the Advertising Identifier / IDFA)
- Ad interaction data (impressions, clicks, and views)
- General device information (device model, operating system version)
- IP address (used for general location-based ad targeting, not stored by us)
This data is collected and processed by Google in accordance with Google's Privacy Policy. We do not have access to personally identifiable information collected by Google.
App Tracking Transparency
On iOS 14 and later, Sudoku will request your permission before allowing ad-related tracking via Apple's App Tracking Transparency (ATT) framework. You can change this permission at any time in your device's Settings > Privacy & Security > Tracking.
Subscriptions
Sudoku Pro subscriptions are processed entirely by Apple through the App Store. We do not collect or store any payment information. Subscription management, billing, and renewal are handled by Apple in accordance with Apple's Privacy Policy.
How Your Data is Stored
All game-related information is stored locally on your device using iOS standard storage mechanisms. This data:
- Never leaves your device (except ad-related data as described above for free users)
- Is not accessible by us
- Is removed when you delete the app
Third-Party Services
Sudoku uses the following third-party services:
- Google AdMob (free version only) — for displaying advertisements. See Google's Privacy Policy.
- Apple StoreKit — for processing in-app subscriptions. See Apple's Privacy Policy.
- SKAdNetwork — Apple's privacy-preserving ad attribution framework, which allows ad networks to measure campaign performance without revealing individual user data.
Children's Privacy
Sudoku does not knowingly collect personal information from children under 13. The free version displays ads served by Google AdMob, which may collect device-level data as described above. If you are a parent or guardian and believe your child has been affected, please contact us.
