Privacy

What we store

Your profile (username, avatar, theme), your linked public wallet addresses, your duel history, ratings, reputation, achievements and transaction records. If you sign in with Google or X we store the provider account identifier and, when the provider supplies it, your email.

What we never store or expose

We never store a secret key for an external wallet. Managed wallet secrets are encrypted with AES-256-GCM and are never returned through an API, logged, or sent to the browser.

Blockchain data

Duel escrow and settlement happen on a public blockchain. Wallet addresses, amounts and transaction hashes are public by nature and linkable to your account.

Local storage

We keep your theme, sound preference and notification setting in your browser. We do not use third-party advertising trackers.

Deletion

You can disconnect at any time from Settings. On-chain records cannot be deleted, but your account and profile can be removed from the Chain Duel database on request.
