Privacy policy

Last updated: 1 August 2026

Chezzo (“the app”) is a chess learning game for children made by Grigory Frolov (Gynsus).

What we collect

Nothing. The app does not collect, store, transmit or share any personal information, device information, identifiers, analytics or usage data. There are no accounts, no advertising, no in-app purchases, no social features and no external links.

Where your progress lives

Lesson progress, trophies, rating and settings are stored only on your device. Deleting the app deletes this data. Nothing ever leaves the device — the app works fully offline and makes no network requests.

Children’s privacy

The app is designed for children and complies with the Apple Kids Category and Google Play Families requirements, COPPA and GDPR by collecting no data at all.

Text-to-speech

Voice lines are generated on the device by the operating system’s built-in speech engine. No audio or text is sent anywhere.

Changes

If this policy ever changes, the updated text will ship inside the app and at this address.
