Privacy Policy

Last updated: March 2026

Trial Friend is a clinical trial search tool for rare disease patients and caregivers. We take your privacy seriously, especially given the sensitive nature of health-related searches.

What we collect

Search queries: When you search for a condition or location, that query is sent directly to ClinicalTrials.gov (a U.S. government service). We do not store your search queries on our servers.

Email addresses: If you sign up for trial alerts, we collect your email address and the condition you're interested in. We use this only to send you notifications about new matching trials. We never sell, share, or rent your email address to third parties, including pharmaceutical companies.

AI translations: When you use the "Translate to plain English" feature, the eligibility criteria text is sent to our server and processed using an AI language model. We do not store the criteria text or the AI response.

What we do not collect

We do not collect your name, diagnosis, medical history, medications, or any other protected health information (PHI). We do not use cookies for tracking or advertising. We do not sell data to anyone.

Third-party services

ClinicalTrials.gov: Trial data is fetched directly from the ClinicalTrials.gov API, operated by the U.S. National Library of Medicine. Their privacy policy applies to data accessed through their service.

AI processing: Eligibility criteria translation is powered by Anthropic's Claude API. The text sent for translation does not include any personal information about you.

Analytics: We use privacy-friendly analytics that do not track individual users or use cookies.

Your rights

You can unsubscribe from trial alerts at any time using the link in any email we send. To request deletion of your email address from our system, contact us at privacy@trialfriend.com.

HIPAA disclaimer

Trial Friend is not a covered entity under HIPAA. We do not collect, store, or transmit protected health information. We are a search tool that helps you find publicly available clinical trial information.
