Privacy Policy
This privacy policy applies specifically to Chessful.
Overview
Chessful is designed to help you improve at chess by analyzing your games and providing personalized training — entirely on your device. Your games, insights, and progress are yours. This policy explains what information Chessful processes, how it is used, and the choices you have.
Data Collection
Chessful processes data generated through your use of the app, including chess games, moves, analysis results, mistakes, training sessions, and progress metrics such as skill scores and estimated rating. This data is used solely to provide the app’s core functionality, including game analysis, mistake explanations, adaptive training, and progress tracking.
Data Storage & Processing
All data is stored locally on your device using Apple system frameworks. Chessful does not operate servers and does not upload your data externally. If you enable system features such as iCloud backups, your data may be included according to your Apple settings.
Third-Party Services
Chessful does not use third-party analytics, advertising, or tracking services. The app uses Apple-provided frameworks such as StoreKit (for purchases) and Game Center (for leaderboards and achievements). Apple may process limited data as part of these services according to your device and account settings.
Children’s Privacy
Chessful is intended for general audiences and is not specifically directed at children under the age of 13. We do not knowingly collect personal information from children.
Changes to This Policy
We may update this privacy policy from time to time. Any changes will be reflected on this page, and the effective date will be updated accordingly.
