Privacy Policy

Authentication Data: If you choose to log in via Apple or Google, we receive your basic profile information (Name, Email, and a unique identifier). This data is saved securely on our cloud servers (Google Firebase Firestore) to seamlessly maintain your profile.

Gameplay Data: All your chess matches, moves, and game preferences are processed and stored entirely locally on your device.

We use third-party services that may collect information used to identify you:

Authentication: Google Sign-In and Apple Sign-In handle your login securely according to their own privacy policies.

Advertising: Our app is free to play and supported by advertisements (such as Rewarded Video Ads for extra hints or undos). We use third-party advertising networks which may collect anonymous identifiers (like Advertising IDs, IP addresses, and basic device information) to serve personalized or non-personalized ads.

We only use your locally stored profile data to personalize your in-game experience (e.g., showing your name). We do not sell, rent, or share any of your personal data.

You have full control over your data. You can permanently delete your account and all associated data from our cloud servers at any time by tapping the “Delete Account” button in the Profile screen. This action instantly wipes your details from both our servers and your device's local secure storage.
