The short version
You can play Scuffed UNO without an account, and we collect as little as possible. We use analytics to understand traffic, ads to keep the game free, and — only if you sign up — an account profile to power the leaderboard.
Playing as a guest
Guest play needs no personal information. The display name and avatar you pick are stored in your own browser (localStorage) along with a reconnect token so you can rejoin a game after a refresh. Guest games are never linked to you — we only count that a game happened.
If you create an account
Accounts are optional and handled by Supabase. We store your email, username, avatar, match results (wins, points), XP, and daily-challenge progress so the leaderboard and your stats work. Signing in with Google shares your basic Google profile (name, email) with us. We never sell this data. To delete your account and its data, email admin@scuffed-uno.online.
Analytics
We use Google Analytics to see visits and which features get used (for example how many games are played). This uses cookies and collects data like device type and approximate location. See Google's privacy policy for details.
Advertising
We show banner ads via Google AdSense to keep Scuffed UNO free. Google and its partners may use cookies to show ads based on your prior visits to this or other websites. You can opt out of personalized advertising at Google Ads Settings. Visitors in the EU/UK are shown a consent prompt before any advertising cookies are set. Ads never appear during live gameplay.
Chat and fair play
In-room chat messages are held in server memory for the life of the room only — they are never stored in a database. Game state lives on our server while you play and is discarded when the room closes.
