Privacy
Short version
We collect as little as we can, and we do not sell it.
What is stored
- Search terms and AI questions. Stored to find gaps in the library. Never stored with an IP address or a user account.
- A coarse session fingerprint. A salted one-way hash that rotates daily, used to count returning sessions. It cannot be reversed to an IP address, and we do not attempt to identify individuals.
- Outbound clicks. Which listing was clicked, not who clicked it.
- Form submissions. Name, email and what you wrote, kept so we can reply.
What is not stored
No advertising cookies. No third-party analytics scripts. No cross-site tracking. Logs never contain email addresses, question text or API keys.
