Privacy Policy

PrediXI is a beta-stage Web3 football prediction platform built for Base App and Coinbase Smart Wallet. By using PrediXI you agree to the terms described in this policy. As a beta product, this policy may be updated as the app evolves.

We collect and store the following data when you use PrediXI:

• Your wallet address (used as your user identity — no username or email required)
• Predictions you submit (match ID, predicted outcome, timestamp)
• XP events associated with your wallet (points earned, source, timestamp)
• Prediction commitment hashes (tamper-evident fingerprints of your predictions)
• Activity metadata (streak count, total predictions, accuracy)

• We do not collect your name, email address, phone number, or any personal identifiers
• We do not collect or store your private key, seed phrase, or wallet credentials — ever
• We do not request access to your wallet beyond signing prediction messages
• We do not collect payment card details or banking information
• We do not use advertising trackers or third-party analytics SDKs

• To record and display your predictions and activity history
• To calculate your XP balance and leaderboard position
• To verify prediction authenticity via wallet signatures
• To operate the platform and detect abuse

When you submit a prediction, PrediXI asks your wallet to sign a message. This signature proves you own the wallet without exposing your private key. The signed message contains only: your wallet address, the match ID, your predicted outcome, and a timestamp. We verify this server-side on Base mainnet.

Your data is stored in Supabase (a managed PostgreSQL database) with server-side access controls. Your wallet address is the only identifier linking your activity to you. We do not sell, rent, or share your data with third parties.

PrediXI is in beta. Data may be reset, migrated, or deleted as part of development. We make no guarantee of permanent data retention during the beta period.
