Ping Zheng built the AI Sudoku app as a free app. This SERVICE is provided at no cost and is intended for use as is.
This page is used to inform visitors regarding policies with the collection, use, and disclosure of information if anyone decides to use this Service.
By using this Service, you agree to this Privacy Policy.
The app is designed to work primarily on your device. I do not directly collect personal data such as your name, email, or phone number.
Some app features may process technical information needed to run the Service, such as app usage data, device information, and diagnostics.
The app requests camera permission (android.permission.CAMERA) only for Sudoku scanning features.
If you import images from your gallery, those images are used for puzzle recognition. Recognition may be performed locally on the device. Image data is not sold by me.
The app may use third-party services such as Google AdMob to display ads. These services may collect device identifiers and usage information according to their own privacy policies.
Please review Google's privacy policy for more details:

Game progress, settings, and puzzle-related data may be stored locally on your device so the app can resume games and keep history.
This Service is not directed to children under 13. I do not knowingly collect personal information from children under 13.
I value your trust and use commercially acceptable means to protect information, but no method of electronic storage or transmission is 100% secure.
This Privacy Policy may be updated from time to time. Changes will be posted on this page.
