What we keep, and who sees it

What we keep

• Your account: your display name, level and settings, and your email if you add one.
• Your games: check-ins (removed shortly after they end), games you set up, and who you've played with — so the two of you see each other's names next time.
• Places you mark or confirm.
• People you've blocked, and reports you send.
• Your alert area, only if you switch on alerts for games nearby: your position rounded to about a kilometre. Switching alerts off deletes it.
• Error reports from the app (what went wrong, your browser and phone model), kept for 30 days.
• How long alerts take to reach your phone: the kind of alert, Android or iPhone, and the delay in seconds, nothing that says whose phone. Kept for 30 days.

Your game log, tournaments and clock settings stay on your phone.

What other people see

When you check in, other players see the place, the time control and your level — not your name. Your name is shown only to people checked in at the same place and people you've played before. A regular game you choose to offer shows its place, day and time. A place you mark is public; who marked it isn't. A player you report isn't told who reported them.

Location

The app uses your phone's location to centre the map and work out distances, on your phone. It isn't stored. The exceptions are the alert area above, and a place you mark, which is stored where you put its pin.

Who else handles it

• Supabase stores the database, in Europe, and handles sign-in.
• Netlify hosts the app.
• CARTO supplies the map tiles, so it sees your IP address and the area you're looking at, as any online map does.
• The OpenStreetMap Foundation runs the place search on the marker, Nominatim. Only when you press SEARCH OPENSTREETMAP, it receives the words you typed, with your IP address, your browser and that the search came from this app — not your phone's location or your name. It keeps its records in the UK and the Netherlands, may study searches to improve its map, and has its own privacy policy.
• Google, Apple or Mozilla deliver notifications, depending on your phone.
• Gmail sends sign-in emails, and feedback arrives in a Gmail inbox, where it may be sorted with the help of an AI assistant.

Nothing is sold, and there are no analytics or tracking.

Age

Accounts are for people aged 18 and over; you confirm this when you sign up. Under-18s play through a parent's family session, which records only that a junior is along — nothing about them.

Deleting your account

Me → Account → Delete my account removes your account and almost everything above. Reports stay on file without your name, places you marked stay without saying who marked them, and a few short-lived system logs clear on their own soon after. A tournament on your phone stays until you clear the site's data.

Your rights

You can ask what we hold about you, ask for it to be corrected or deleted, or object to how it's used: write to hello@chesspluscoffee.com. You can also complain to Ireland's Data Protection Commission (dataprotection.ie).
