What we keep, and why

Browsing Fieldbook stores nothing about you. The public catalog is static and served without cookies or trackers.

When you sign in we keep your email address and the account identifier issued by our sign-in provider (Clerk) so we can attach API keys and a plan to you. API keys are stored as one-way hashes; we cannot recover a lost key, only issue a new one.

Each call to the MCP server records the tool name, the key used and a timestamp. We use that to show you your own usage and to enforce plan limits. Requests are not stored.

If you subscribe, billing is handled by Stripe. We store the Stripe customer and subscription identifiers, never card details.

To delete your account and everything above, email the address listed on the credits page or delete the account from your dashboard. Deletion is immediate.
