Privacy Policy

Data Collection. Prof. Peptide does not collect personal information beyond what is voluntarily submitted (e.g., waitlist email). We do not use tracking pixels or sell data to third parties.

Analytics. We may use privacy-respecting analytics (e.g., aggregate page view counts) to understand site usage. No individual-level tracking is used.

Cookies. We use minimal cookies required for site function. We do not use advertising cookies.

AI Chat Assistant. Questions you type into the chat assistant are logged so we can see which topics the site fails to answer and improve its coverage. We store the question, which pages were retrieved to answer it, timing and token counts, and a hashed form of your IP address — never the address itself. We do not store the assistant’s replies. These records are automatically deleted after 30 days. Your question is also sent to Anthropic’s API, which generates the answer, and is handled under their privacy policy. Please do not enter personal, identifying, or health information into the chat — it is a research tool, not a medical or account service.

Third Parties. We use Vercel for hosting, which may log standard server request data (IP address, user agent) per their own privacy policy.

Contact. Questions about privacy can be directed through the site contact page.
