Your privacy is important to us. This Privacy Policy outlines how your information is handled when you use the Sudoku Master application ("the App").
The App is designed to be fully functional offline. We do not require you to create an account, nor do we collect personally identifiable information (PII) such as your name, email address, or phone number.
All game progress, statistics, settings preferences, and saved games are stored entirely locally on your device using Android DataStore and Room Database. This data never leaves your device and is solely used to provide the game's core functionality.
The App integrates with Google AdMob to display advertisements. AdMob may collect and use certain data for advertising purposes, such as:
For more information on how Google AdMob handles data, please review the Google Privacy Policy.
Additionally, the App may use Firebase Analytics to aggregate anonymous usage statistics (such as feature usage and crash reports) to help us improve the application. This data is fully anonymized.
While we do not transmit local game data to our servers, we rely on Android's secure application sandbox to protect the data stored locally on your device. We encourage users to secure their devices with PINs, passwords, or biometric locks to prevent unauthorized physical access to their data.
The App is suitable for general audiences but we do not knowingly collect personal information from children under 13. Given our offline-first architecture, no personal data from minors is harvested or transmitted by us.
We may update our Privacy Policy occasionally. We will notify you of any changes by posting the new Privacy Policy within the App or on this page. You are advised to review this Privacy Policy periodically for any changes.
If you have any questions or suggestions about our Privacy Policy, do not hesitate to contact us at drew.developer@gmail.com.
