Privacy

We store your wallet address when you sign in, the 16 choices you submit, your card inscriptions and the signatures that prove you wrote them. These are public: they appear on result cards and in the API.

We keep short-lived counters per IP address to stop abuse; they expire within a day. We set one cookie, an HttpOnly session cookie, so you stay signed in.

We don’t use analytics or advertising trackers. Fonts load from Google Fonts and the 3D library from jsDelivr.
