Privacy policy
Last updated: 25 October 2026
Chuss is a chess-variant game for iPhone and Android, made by the Chuss Team ("we"). This policy explains what information the app collects, why, and what you can do about it. If you have any questions, email support@playchuss.com.
Playing without an account
You can play against the computer and read the rules without signing in. In that case Chuss doesn't send anything about you to our servers.
What we collect when you create an account
- Your email address, used only to sign you in (we email you a code or a link). We don't send marketing email and never show your address to other players.
- Your username, which other players can see.
- Your games: the moves, clocks, results and variant of each online game, and your rating, number of ranked games, wins, losses and draws. Your opponent can see the games you played together; your username, rating and record appear on the leaderboard.
- Your friends: friend requests and friendships between you and other players.
- Reports and blocks: if you report a player, the reason, anything you write and who you reported, which only we can see (the player isn't told who reported them). If you block a player, who you blocked, which only you can see.
- A push notification token, only if you allow notifications, so we can tell you when a friend challenges you. Only our servers can see it.
Our service providers' servers also keep short-lived technical logs (such as IP addresses and request times) to run and secure the service.
What we don't do
- No advertising, and no advertising or analytics trackers in the app.
- We don't sell or rent your information, or share it for anyone's marketing.
- We don't track you across other apps or websites.
Who processes your information
We use a small number of providers to run Chuss, only for the purposes above:
- Supabase: hosting, database and sign-in.
- Resend: sending sign-in emails.
- Expo, Apple and Google: delivering push notifications, if you allow them.
How long we keep it, and deleting your account
We keep your account information for as long as you have an account. You can delete your account at any time in the app: Profile → Delete account. This permanently deletes your account, email address, username, rating, record, friends, blocks and notification token. Games you played stay in your opponents' history, with your side shown as a deleted player, and reports you made stay with us, no longer linked to you. You can also ask us to delete your account by emailing support@playchuss.com.
Your rights
Depending on where you live, you may have the right to access, correct, export or delete your information, or to object to how we use it. Email us and we'll help.
Children
Chuss isn't directed at children under 13, and we don't knowingly collect information from them. If you think a child has created an account, contact us and we'll delete it.
Changes
If we change this policy, we'll update the date at the top, and for significant changes we'll let you know in the app.
