Privacy

Signbrief is in private beta. This page describes what we collect, what we do with it, and what we don't do. Plain English first, lawyer-speak never.

What we collect

• Your email + signings-per-week estimate when you join the waitlist. That's it for the public-facing site.
• The PDF you upload for parsing. We send it to Anthropic's API, get back structured JSON, return it to you. The PDF is not stored on our servers after processing.
• The parsed JSON stays in your browser (localStorage) unless you explicitly save it as a job. Cloud sync ships when we move to Supabase — at that point you'll be asked to opt in.
• Basic server logs (IP, user-agent, request paths) for security and abuse prevention. Standard. No analytics cookies, no third-party trackers.

What we don't do

• We do not sell your data. To anyone. Ever.
• We do not share signing details with title companies, lenders, the IRS, or any third party other than Anthropic (the model provider, which has its own privacy terms — see anthropic.com).
• We do not train models on your data.
• We do not use third-party advertising trackers, social tracking pixels, or behavior profiling.

Anthropic

Signing-instruction PDFs and follow-up drafts are processed via the Anthropic Claude API. Anthropic does not train models on API-submitted data by default (see anthropic.com/privacy). If their policy changes we'll surface it here.

Your rights

You can request deletion of any data we hold about you by emailing hello@signbrief.com. We'll honor it within 30 days, faster if technically possible.

Beta caveat

Signbrief is in private beta. The product is changing. This page will change with it. We'll never silently weaken your privacy — any meaningful change gets a notice in the app and to your email.
