Your privacy
Your health information is yours.
A person’s condition and pre-screen answers are sensitive health data, and we build for that from day one. This page explains, in plain terms, what we collect and the control you keep.
Last updated October 2, 2026 · This is a clear summary, not a substitute for a full legal policy.
What we collect
To help you find and understand studies, Clin2 records what you search for, the studies you view, and the answers you give during an optional pre-screen. We also collect basic technical information (device, referrer, and similar) to keep the service working and to learn what patients need.
Before you create an account, this activity is tied to an anonymous identifier — not your name. If you sign up, we link that activity to your account so your saved searches and studies are there when you return.
We don’t sell your data
We do not sell your personal information or your health data — not to pharmaceutical companies, contract research organizations, insurers, data brokers, or advertisers. No one can pay us for an introduction to you.
We should be just as clear about what we do sell, because “we don’t sell your data” is a sentence that can hide a lot. Study sponsors and research teams can pay for de-identified, aggregate information about demand: how many people search for a given condition, in which regions, and which eligibility rules most often turn people away. That is counts and patterns across many people. It carries no names, no contact details, no answers, and no individual records — and it isn’t built in a way that could return one.
Your identifiable information leaves Clin2 in one situation only, and it isn’t a sale: when you apply to a study and choose the site. Your contact details and the answers you chose to share then go to that study team, because that is what applying means. Searching, reading, and pre-screening send nothing to anyone.
How we treat sensitive health data
Your condition and pre-screen answers can reveal sensitive things about your health. We keep this identifiable health data separate from our general, de-identified analytics, and we access-control it. This category is governed by consumer-health-data laws such as Washington’s My Health My Data Act, and we architect for consent, audit logging, and deletion accordingly.
Using Clin2 inside ChatGPT and other assistants
You can connect Clin2 to assistants such as ChatGPT. When you ask the assistant to find or check a study, it sends Clin2 only what that request needs: the condition and any details you chose to share for the search (for example age, stage, biomarkers, past treatments, or a place), a study’s NCT number, or the facts to compare against a study’s requirements. Clin2 never receives your conversation history.
For a search or a comparison, we use those details to answer that one request and then discard them. We do not store the health facts sent for a search or a comparison, and we do not attach them to you. We keep operational records — which tool ran, how long it took, whether it worked, how many studies came back — together with a scrambled (hashed) version of the anonymous ID the assistant provides, so we can keep the service reliable and prevent abuse. Separately, we count which conditions are searched for and in which general area, with no identifier of any kind, as part of the de-identified demand information described above.
If you choose to link your Clin2 account to an assistant, it can do only what you approve on Clin2’s own permission screen: for example, read your saved studies and applications, save a study, or take a study’s pre-screen and prepare an application. You can disconnect it at any time from your dashboard.
If you answer a study’s pre-screen questions in the assistant, it passes your answers to Clin2 and we store them in your account, just as if you had answered on our website. An application is never sent to a study team until you open Clin2’s consent page, review exactly what will be shared and with which study and location, and agree there yourself. The assistant cannot agree for you. You can withdraw an application at any time, and withdrawing also withdraws that consent. How the assistant itself handles your conversation, including the questions and answers you type there, is governed by its provider’s privacy policy (for ChatGPT, OpenAI’s).
Consent comes first
We never share your identifiable health information with a study, sponsor, or site unless you give explicit, recorded consent for that specific purpose. Consent is versioned, and you can withdraw it at any time. Exploring trials and pre-screening on Clin2 does not enroll you in anything or hand your details to a third party.
How long we keep it
Your account information, saved studies, pre-screen answers, and applications stay in your account until you delete them or your account. Detailed activity records (searches, study views, and similar events) are deleted after 12 months; we keep only daily counts that identify no one. Anonymous pre-screens, started without an account, are deleted after 90 days. An assistant’s access to your account expires on its own unless it is renewed, and ends immediately when you disconnect it.
Your control: export and deletion
You can export everything we hold about you, and you can delete your account and associated data, from your dashboard. When you delete, we remove your identifiable data and your behavioral profile.
A note on HIPAA
Clin2 is a consumer service and is not, by itself, your healthcare provider. Some future relationships with sites and sponsors can bring health-privacy obligations into play; where they do, we handle the relevant data under the appropriate safeguards.
