What we store, and why.

Signing in stores your wallet public address. No email address, name, phone number or payment detail is collected, and no private key or seed phrase is ever requested or transmitted.

Against that address the platform stores your saved symbols, your analysis history, your plan, and a daily usage counter.

Sign-in uses a signed message, not a password. The server issues a single-use challenge, your wallet signs it, and the server verifies the signature against your public key. The challenge is deleted on use so a captured signature cannot be replayed.

The resulting session is a signed cookie containing your public address and an issue time. It carries no other data and expires after 30 days.

Market data is requested from Alpha Vantage by the server. Those requests contain the ticker symbol only — never any information about you.

If AI narration is enabled, the computed indicator values and classifications are sent to Anthropic to be written into prose. That payload contains no wallet address and no user identifier.

Analysis history and watchlists persist until you remove them. Disconnecting a wallet ends the session but does not delete stored records.

Cached market data is stored per symbol and is not associated with any user.
