Privacy Policy

Last updated: June 2026

This policy explains what data ChessMemory collects and how it is used. The data controller is Brice Patrick Nana Fondja, a sole proprietor based in Canada (operator of ChessMemory).

1. Data you create

Your chess data (opening repertoires, games, studies, puzzles, progress, settings) is stored locally on your device by default. The app works fully offline.

2. Account & cloud sync (optional)

If you choose to create an account to sync across devices, we store your email address and an encrypted copy of your chess data with our hosting provider (Supabase). This data is protected so that only your account can access it. We do not sell or share your data with third parties.

3. Payments

Purchases are processed by Paddle.com, our Merchant of Record. We do not receive or store your full payment-card details; those are handled by Paddle under their own privacy policy.

4. Analytics

We collect minimal or no personal analytics. Any usage data, if collected, is aggregated and not used to identify you.

5. Your rights

You can delete your local data at any time from within the app. To delete your account and synced data, contact us at the address below and we will remove it.

6. Contact
