Privacy Policy
Last updated: 15 October 2026
This page explains what Onchain Rivals stores about you and why. We keep it to what the game needs.
What we store
- Sign in with X: your X user ID, username, display name and profile picture, provided by X when you sign in. We use your username to give you your own card if you're a fighter in the game. We can't post on your behalf.
- Wallet: your public wallet address, and the transactions you send to buy $RIVALS (they're public on Base anyway).
- Profile: the name and picture you choose, if you create a profile.
- Game data: your cards, $RIVALS balance and history, invite code, Arcade progress and waitlist suggestions.
- On your device: guest progress and settings (like sound) are kept in your browser's local storage.
What we don't do
We don't sell your data, show third-party ads or track you across other sites. We don't ask for your email in the game.
Who processes it
Accounts and game data are stored with Supabase. The site is hosted on Vercel. Fonts load from Google Fonts. X and your wallet provider handle sign-in under their own privacy policies.
Public information
Market listings, the waitlist and leaderboards are public by design. Your cards, balance and history are private to your account.
Deleting your data
Contact us on X at @onchainrivals and we'll delete your account and game data. On-chain payments can't be deleted by anyone.
