Privacy Policy
Last updated: March 28, 2026
Simply Sudoku ("the App") is developed by Wei Wang. This privacy policy describes how the App collects, uses, and protects your information.
Information We Collect
The App collects anonymous usage analytics through Firebase Analytics to help us understand how the App is used and improve the user experience. This includes information such as app launches, feature usage, puzzle difficulty preferences, and general device information (device model, OS version). We also use Apple's iCloud Key-Value Storage to sync a randomly generated anonymous user identifier across your devices. This identifier is not linked to your personal identity.
Information We Do Not Collect
The App does not collect any personally identifiable information such as your name, email address, or location. The App does not require you to create an account. Your puzzle progress and game settings are stored locally on your device and in your personal iCloud account, and are not accessible to us.
Third-Party Services
The App uses Firebase Analytics, a service provided by Google, to collect anonymous usage data. Firebase may collect certain device and usage information as described in Google's privacy policy. No personal data is shared with third parties for advertising or marketing purposes.
Data Security
We value your privacy and take reasonable measures to protect the information collected. All game data is stored locally on your device and synced through your personal iCloud account using Apple's built-in security mechanisms.
Children's Privacy
The App does not knowingly collect personal information from children. Since the App does not collect personal data from any user, it is safe for use by individuals of all ages.
Changes to This Privacy Policy
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this page periodically.
