Privacy policy

Last updated 5 November 2026

Wings Chess is built to work without an account. This page explains, in plain words, what we store and who helps us run the service.

Without an account

Your games, lessons, puzzle history and settings are saved only in your browser (local storage). We don't receive them. Clearing your browser data deletes them.

With an account

  • Your email address, used to sign you in (by email link, password or Google).
  • A copy of your chess progress (games, lesson stars, puzzle results, settings) so it syncs between your devices.

We don't sell your data, show ads, or use advertising trackers.

Friend games

When you play a friend by link, the game is stored on our server so both players see the same board: the name you type, the moves, the clocks and the chat messages. Anyone with the link can watch the game. Don't put personal information in your name or chat. To have a friend game deleted, email us its code.

Services we use

  • Vercel hosts the website (standard server logs such as IP address and browser type).
  • Supabase stores accounts, synced progress and friend games, and relays live game updates.
  • Brevo sends sign-in emails.
  • Groq powers the AI coach and bot chat. When you use them, the chess position, recent moves and your message are sent to generate a reply. Don't put personal information in chat messages.
  • Lichess and Chess.com: if you import games, we request your public games from their APIs using the username you enter. Puzzles come from the Lichess open database.

Your choices

  • Use Wings Chess without an account at any time.
  • To delete your account and synced data, email hello@wingschess.com from the address you signed up with. We'll delete it within 30 days.

Children

Chess is for everyone. Children under 13 can use Wings Chess without an account; an account should be created by a parent or guardian.
