Last updated · 2 August 2026
CupRank is a real-world coffee brewing game: everyone brews the same coffee, the cups are judged blind, and the results become a shared record. This page says what we collect to make that work, what stays private, where it lives, and how to leave.
What we collect
- Your email address — used to sign you in (a one-tap link, or Google / Apple sign-in) and never shown publicly.
- Your @handle — the public name you pick at first sign-in. Your real name appears only if you switch it on; it is off by default.
- Game records — brews, recipes, measurements, ballots, placements and ratings. Results are public by design: finished games, leaderboards and profiles are the product.
- Photos you submit — at check-in you may photograph the coffee bag or a refractometer reading as evidence. These are uploaded to our storage and are accessible to anyone with the link, the same as the game record they belong to.
Camera and photo permissions
The camera scans a game’s QR code to join — scans are processed on your device and nothing is recorded or uploaded. Saving a result card to your photo library happens only when you ask, with your permission, and stays on your device.
What we don’t do
No ads. No analytics or tracking SDKs. No selling or renting personal data — to anyone, ever. We collect nothing the game itself does not need.
Where your data lives
Data is stored with Supabase (database, authentication and file storage) and the website is served by Vercel. Sign-in emails are delivered over Gmail. If you sign in with Google or Apple, that provider confirms your email address to us and we store nothing else from your account there. Each of these providers processes data on our behalf under their own security terms; none of them may use it for their own purposes.
What other people can see
Your @handle, your finished games, your placements and your position on leaderboards are visible to others — that is the point of a ranked public record. Your email address is never displayed. Your real name is shown only if you turned it on, and you can turn it back off at any time.
Deleting your account
Delete it yourself, in the app or on the web: sign in, open Profile, and tap Delete account. It happens immediately. Or email dev@cuprank.app from the address you signed up with and we will do it for you.
Either way the same things happen: your account, your email address and your photos are deleted, and your entries in shared game records are anonymised — a game’s outcome belongs to everyone at the table, so the result survives but your name comes off it.
Children
CupRank is not directed at children under 13 and we do not knowingly collect their data. If you believe a child has an account, contact us and we will remove it.
Changes
If this policy changes, the new version appears here with a new date at the top. Material changes will be called out in the app.
