Privacy Policy
How STACK XI handles wallet connections, on-chain data, and local progress.
What we collect
When you connect a wallet, we read your public on-chain address and contract interactions (NFT mints, BCC predictions). Culture task progress (XP, streaks) is stored locally in your browser keyed to your wallet address — not on our servers in v1.
What we do not collect
We never ask for your private keys or seed phrase. Private keys stay in your wallet. We do not sell personal data.
Third parties
Blockchain transactions are public on Base. Wallet providers (e.g. Coinbase Wallet, browser extensions) and RPC providers (e.g. Alchemy) process requests under their own policies. Social task links open X and Farcaster on their platforms.
Local storage
You can clear culture mission progress by clearing site data in your browser. On-chain NFT ownership and prediction history remain on Base.
