Privacy Policy

Site analytics (Google Analytics 4).We use GA4 to measure aggregate, non-identifying usage: which pages are viewed, general traffic sources, approximate region, device type, and which outbound vendor links get clicked (by vendor and compound, so we can see what people are researching). This is standard web analytics. GA4 sets cookies and processes usage data under Google's terms. We do not use it to build advertising profiles of you.

No accounts to browse.The public site does not require you to register or provide personal information. If you choose to join our email dispatch, we collect only the email address you submit, and only to send the updates you asked for. You can unsubscribe at any time.

No sensitive data requests.We never ask for health records, payment card numbers, passwords, or government identifiers. Purchases happen on third-party vendor sites under their own privacy policies, not on PepEvolution.

PepEvolution exposes its vendor and COA data to AI agents through aModel Context Protocolserver at /mcp. This endpoint is read-only and stateless. It accepts a compound or vendor name, returns our graded, COA-backed answer, and stores nothing about the caller. We keep only aggregate, non-identifying server logs (which tool was called and the resolved compound or vendor) to understand usage volume. No accounts, no cookies, no personal data pass through it.

Some outbound vendor links are affiliate links. If you click one and buy something, we may earn a commission at no extra cost to you. When you follow an affiliate link, the destination vendor and its affiliate network may set their own cookies to attribute the referral. That happens on the vendor's site under their privacy policy. Affiliate revenue never affects which vendors we list, how we grade them, or how we rank them. See ourfull disclosures.
