Privacy policy

ChessGuild runs chess tournaments for clubs, schools and workplaces. We keep as little data as we can and delete most of it quickly.

What we store

• Organizers: your email address, used to send you login links, and the tournaments you create (name, format, start time, settings).
• Players: the name a player types when they open their link, and their games (moves, clock times, results). Players do not have accounts and we do not ask for an email address.
• Technical data: our web server and our network provider log IP addresses and requests for security and for keeping the service running.

How long we keep it

• Tournaments that the organizer has not saved, including player names and all games, are deleted automatically 7 days after the tournament starts.
• Your email address is kept for as long as you have an organizer account. You can ask us to delete it at any time.
• Server logs are kept for a short time and then rotated away.

Cookies

Organizers get one session cookie that keeps them logged in. We use no advertising or tracking cookies. Players do not get cookies: their link is how the site recognizes them, so keep it private.

Who processes data for us

We use a hosting provider for our server, a database provider, an email service for login links, and a network provider (DNS and traffic protection). They process data only to run ChessGuild for us.

Your rights

You can ask what we hold about you, ask us to correct or delete it, and object to how we use it. Organizers, please tell your players that their names are shown to the other players in the tournament and are deleted as described above.
