attest checks artifacts. It does not want to know anything about you, so it stores as little as possible.

What we store

• Call counters — how many checks a caller made, per day, so the free tier can be enforced. No artifacts, no prompts, no results.
• Feedback you send us — a yes/no answer and, if you write one, a comment. Stored with a short hash of the caller, not an IP address.
• Requests for early access — the email you typed, and whatever you wrote about what you verify.

What we do not store

• Artifacts you check, and the verdicts, beyond the counters above;
• your prompts, model outputs, or anything you paste into the demo;
• your IP address — the server sees the tunnel's address, not yours.

Payments

Payments settle on-chain via x402 (USDC on Base). The receipt is signed by us and verifiable offline. The wallet you pay from is visible on the public blockchain, as any blockchain payment is — that is a property of the network, not of this service.

Deletion

Write to the address in the footer of any page and we will delete the feedback or request you name. Counter aggregates can be reset on request.
