Privacy Policy

Last updated: May 2, 2026

1. Data We Collect

When you sign in via OAuth (Google, Lichess, etc.) we receive your username, email address, and profile picture URL from the provider. We store this to identify your account. We also store your training history (positions attempted, moves made) to power the training features.

2. How We Use Your Data

Your data is used solely to operate and improve the ChessGenie service. We do not sell or share your personal data with third parties except as required to process payments (Stripe) or comply with law.

3. Stripe Payments

Payment processing is handled by Stripe, Inc. When you subscribe, Stripe stores your payment details. We only receive a customer reference ID — we never see or store your card number. Stripe's privacy policy applies to payment data.

4. Your GDPR Rights

Under EU law (GDPR) you have the right to access, correct, or delete your personal data. You may also request a copy of your data or withdraw consent at any time. To exercise these rights, contact us at the address below.

5. Cookies

We use cookies to keep you logged in, including a session cookie and, for guest accounts, a guest token cookie. We also use Google Analytics to understand site usage. We do not use advertising cookies.
