Privacy Policy

The short version

We keep as little about you as we can. Your account holds your email, a password hash, a username, and your subscription status. The app sends us a summary of each game you play with it, so your dashboard can show your statistics. Payment details go to Stripe, not to us. The community board is public. We do not sell data and we do not run advertising.

Who is responsible

The operator of Chess Vision is the controller of the data described here. Requests about your data can be raised on the community board, where they are handled by the team, or by any contact route shown on this site.

What we collect and why

• Account data: email address, a hashed password, your username, the date you registered, your role (user, friend, admin), and whether your subscription is active and until when. Needed to sign you in and to know what you are entitled to.
• Session data: sign-in tokens kept in your browser and, if you choose Keep me signed in, in your computer's keychain or credential store. Needed so you do not have to sign in every time.
• Game summaries: when a game played with the app ends, the app uploads the result, the number of moves, your colour, the target rating you chose, the opponent's rating as read from the screen, the app's accuracy figures for the game, the app version, and the moves of the game. Used for the statistics on your dashboard and, in aggregate and without your identity, to improve the app.
• Community content: threads, replies, and votes you make, with your username and the time. Public by design.
• Payment data: Stripe processes payments and tells us only whether a subscription is active, its period, and a customer reference. We never receive card numbers.
• Technical logs: the app writes a log file on your own computer. It stays there unless you send it to us yourself. Our hosting providers keep standard server logs (IP address, time, request) for security, for a short period.

What we do not collect

The app does not send us screenshots or the contents of your screen. Board reading happens entirely on your computer. We do not track you across other websites, we do not use advertising or analytics cookies, and we do not ask for your name, address, or date of birth.

Where the data lives

Accounts, game summaries, and community content are stored with Supabase, our database provider, on servers in the European Union. The website is served by Netlify. Payments are processed by Stripe. Each of these providers processes data under an agreement with us and its own privacy policy; we do not give them more than the service needs.

How long we keep it

• Account data: as long as your account exists, then deleted within 30 days.
• Game summaries: as long as your account exists. You can ask us to delete them earlier.
• Community posts: as long as the board exists, unless you delete them yourself or ask us to. Deleting a post removes its content and its votes.
• Payment records: as long as tax and accounting law requires, typically up to ten years, held by Stripe and in our accounts.
• Server logs: up to 30 days.

Your rights

Under the GDPR and similar laws you can ask to see the data we hold about you, have it corrected, have it deleted, receive a copy in a portable form, restrict or object to some processing, and complain to your data protection authority. Deleting your account deletes your account data and game summaries; community posts are kept unless you ask for them to be deleted too, because other people's replies depend on them.

To exercise a right, raise it on the community board or through any contact route on this site. We answer within one month.

Cookies and local storage

The website uses your browser's local storage to keep you signed in and to remember small preferences. It sets no advertising or tracking cookies. Stripe's checkout and portal pages set their own cookies under Stripe's policy.

Children

The service is not for children under 16. If we learn that an account belongs to a child under 16 without the consent required where they live, we delete it.

Changes to this policy

We may update this policy. The date at the top shows the latest version. For material changes we tell you in the app or on the dashboard before they take effect.
