Chess Guru AI ("the app") is an Android chess learning app published by AI365Apps. It has no accounts, no sign-in, no ads shown inside the app and no in-app purchases. The lessons, puzzles, games and analysis all run on your phone. The only information the app sends off your phone is the Meta install measurement described below.
Your chosen experience level and daily practice goal, lesson progress, puzzle results, streaks, the games you play and the positions saved in the Mistake Trainer are stored only on your phone. We cannot see them. Uninstalling the app deletes them. Automatic cloud backup of the app's data is switched off.
Move analysis, evaluations and the opponent in "Play" come from the Stockfish chess engine running inside the app on your phone. Nothing about your games or positions is sent to us or to any AI service. The app does not need an internet connection for lessons, puzzles or games. Coach explanations are generated on your phone.
If you use the read-aloud option, the app asks your phone's built-in text-to-speech service to speak the explanation text. That service is provided by your phone or by the speech engine you have installed (for example Google), and is governed by that provider's own privacy policy. The app itself does not record or send audio.
We advertise this app on Facebook and Instagram. To learn whether an ad led to an install, the app includes the Meta (Facebook) SDK for Android. When you open the app, the SDK sends Meta basic app-activity events (such as "app installed" and "app opened"), your device's Android advertising ID, your IP address and basic device information (device model, Android version, app version). It does not receive your name, your lesson progress, your puzzle results or your games. Meta uses this information under its own privacy policy, and we use it only to measure and improve our ads. You can reset or delete your advertising ID, or opt out of ads personalisation, in Android Settings → Privacy → Ads. We do not sell your data.
We collect no name, email address, phone number, contacts, photos, location or microphone audio, and we do not read your hardware device identifiers. Apart from the Meta install measurement described above, the app does not use analytics or tracking services, and we do not sell data.
Chess Guru AI is a general chess learning app intended for users aged 13 and over. Younger players should use it with a parent or guardian. It has no social features, no chat, no links to strangers and no purchases. We do not knowingly collect personal information from a child under 13.
Chess Guru AI is an independent app. It is not affiliated with or endorsed by FIDE, any national chess federation, or any other chess website or company. The "training rating" shown in the app is an internal estimate and is not an official chess rating.
