Data collected

The chat endpoint (POST /chat) accepts only the question you type and returns an evidence-checked response; the public-signals endpoint accepts no user input at all. Server logs record request timing and adjudication outcomes for reliability and security -- see "Chat handling" below for what that does and doesn't include.

Data not collected

Chat handling

Your question is sent to the backend to generate an answer and is not logged. Server-side telemetry per request includes only a correlation id, timing, and adjudication scores (evidence coverage, policy result) -- never the question text, system prompt, provider raw output, or your IP address in application logs. See the Evidence-Grounded RAG Evaluator lab for how a response is validated.

Most questions are answered entirely from this site's own public evidence and never leave the backend. When a question doesn't match a known evidence-backed answer, the raw question text is forwarded to a third-party AI/LLM provider, and the candidate answer still has to pass the same evidence and safety gates before it's shown to you. The backend screens every question for phone numbers, email addresses, street addresses, and hourly-rate figures before forwarding, and refuses to process the request if any are found -- a pattern match, not a guarantee, so don't paste anything confidential (names, private correspondence, internal documents) into the chat box.
