TeamChess (teamchess.co) is a site for chess games between teams. This page says what it keeps about you, why, and how to have it removed. It doesn't sell anything about you or show ads.

What it keeps

• A player id, made the first time you open the site and kept in your browser, so your games and rating follow you. You don't need an account to play.
• The name you choose, your rating, and your games: the moves, which side you were on, what you voted for, and the result. Other players see your name, rating and votes in games you play.
• If you make an account: your username and a salted hash of your password (never the password itself). If you sign in with Google: your Google account id and email address, used only to sign you in.
• If you bring your Lichess rating: your Lichess username and rating. The Lichess access token is used once to read the rating and then revoked; it isn't kept.
• If you turn on reminders: your browser's push address, used only to send the reminders you asked for.
• Groups and tournaments you make or join, and their names.
• Feedback and ideas you send, and your votes on ideas.

Apps that make games for you

TeamChess can be added to Slack, Claude, ChatGPT, Codex and other AI apps. They can only create a game or a tournament and hand back its link. They receive the team names, tournament name and clock you ask for, and the link that comes back. They can't play, vote, or read anything about you or your games. The Slack app uses only its slash command and can't read your messages.

Analytics

The site counts page views and actions (like "made a game") with PostHog, through teamchess.co, to see what works. It doesn't build a profile of you across other sites.

Where it's kept

On Cloudflare, which runs the site. Google, Lichess, Slack and PostHog handle the parts named above under their own policies.

Removing it

Clearing the site's data in your browser forgets your player id on that device. To have your account, games and name removed from the server, email hello@autobirds.com or use the Feedback button on any page, and include your player name; it's done within 30 days.

Children

Families play together on TeamChess. A child can play without an account and without giving any personal details; accounts and Google sign-in are for people 13 and over.

Changes

If this changes, the new version is posted here with a new date.
