Treble is a football prediction game you play with friends. There is no money, no stake and no prize. This page says exactly what the app stores, why, and how to erase it.

What we store

• Your account: email address, password (encrypted, never readable by us), username, avatar, and the city you pick – the city is optional.
• Your game: your predictions, boosts, title pick, the leagues you join and when you joined them.
• On your phone only: preferences (language, theme) and demo-mode state. These never leave the device and go away with the app.

What we don't store

No advertising. No ad trackers. No analytics tools. No location: the city is text you choose from a list, not a position read from your phone. Nothing is sold or handed to anyone else.

Who sees what

Your predictions are visible to members of the leagues you share with them, and to nobody else. That limit is not merely displayed: the database itself refuses to serve the predictions of someone you share no league with. A prediction only becomes visible once the match has kicked off.

Who hosts and who helps

• Supabase – database hosting and account management.
• Vercel – hosting for the web version.
• API-Football – fixtures, results and odds. No data about you is sent to it: the exchange is about football matches only.

How long

As long as your account exists. You can delete it at any time from the app (Settings → Delete my account): account, profile, predictions and league memberships are erased. Leagues you created carry on for their other members.

Your rights

You may access, correct, export or erase your data, and object to its processing. Deletion is immediate from the app; for anything else, write to write to us. If an answer doesn't satisfy you, you can contact your country's data protection authority.

Age

Treble is not aimed at children and is not intended for them. We do not knowingly collect data about anyone under 15.

Changes

If this page changes, the date at the top changes with it. Any change that would widen what we collect will be announced in the app before it takes effect.
