Sudokyu is a Sudoku puzzle game. Your privacy is important to us. This policy explains what data the app does and does not collect.
All game data—including your progress, settings, and statistics—is stored locally on your device using AsyncStorage. No accounts are required, and no game data is transmitted to any server.
Sudokyu does not collect, store, or transmit any personal information. There are no user accounts, no sign-in, and no tracking of any kind.
Sudokyu does not use any analytics services. We do not track how you use the app.
The app may send minimal, anonymous crash reports through Expo's built-in error reporting (powered by Sentry). These reports contain technical information about the crash (such as stack traces and device type) but do not include any personally identifiable information.
Sudokyu offers an optional in-app purchase to unlock premium features. Purchases are processed by Apple (App Store) or Google (Play Store) and managed through RevenueCat, a third-party purchase-management service. To process your purchase and allow you to restore it across your devices, RevenueCat receives non-personal purchase information such as transaction and receipt details and an anonymous purchase identifier. This data is used solely to deliver and restore your purchase. We never receive or store your payment card details—those are handled entirely by Apple or Google. See RevenueCat's privacy policy at https://www.revenuecat.com/privacy for more information.
Other than the crash reporting and purchase services described above, Sudokyu does not share any data with third parties. There are no ads and no social integrations.
Sudokyu does not knowingly collect any information from children. The app does not require or collect personal data from any user, regardless of age.
