Privacy Policy

What we collect

• Display name — entered by you in the lobby. Not verified or linked to any identity.
• Device identifier — a random UUID generated automatically the first time you visit, stored in your browser's local storage under the key vb-bingo-device-id.
• Language preference — EN or HU, stored locally under vb-bingo-lang.
• Game progress — your board, marked cells, and bingo status, stored locally and synced to our server for the duration of the match.
• Chat messages — text you send in the match chat, stored on our server.

Where it's stored

Device ID, language preference, and game progress are stored in your browser's local storage — they never leave your device unless you join a match. Your name, marked count, bingo status, and chat messages are stored in our server (Upstash Redis, encrypted in transit, hosted in the EU/US).

How long we keep it

Server-side data (leaderboard, chat) expires automatically approximately 5.5 hours after kick-off. After expiry, all data for that match is permanently deleted with no backups. Local storage data persists in your browser until you clear it or uninstall the app.

Who can see your data

Your name and chat messages are visible to everyone who joins the same match room. There is no private mode. There is no account system — we do not verify who you are.

Analytics

We use Vercel Analytics to measure aggregate page traffic. No cookies are used; no personal data is collected or shared with third parties.

Third-party services

• football-data.org — match fixture and squad data.
• Upstash — Redis server (leaderboard & chat storage).
• Vercel — hosting, CDN, and analytics.

Your rights

You can delete your local data at any time by clearing your browser's local storage. Server-side data expires automatically. To request early deletion, contact us below.
