Your information. Clear boundaries.
How Clinical Trial Zone handles information when you read articles and use its planning tools.
Scope
This policy describes Clinical Trial Zone's educational website. Updated November 10, 2026.
Reading and using the website
You can read articles and use every tool without creating an account or submitting an email address. The website does not operate a mailing list or collect subscription information. We do not sell visitor information.
Tools and local storage
Calculators and planning tools run in your browser. Tool inputs are not sent to the CTZ server. “Save on device” keeps a plan in this browser's local storage; the tool's Reset control removes its saved plan. On a shared device, avoid saving anything you would not want another user to see. Do not enter names, diagnoses, participant identifiers, or other sensitive health information in editable labels.
Hosting and service records
The hosting provider may process technical information such as IP addresses, requested URLs, and browser details to deliver and protect the website. This release does not include advertising pixels, session recording, account cookies, or third-party form verification.
Contacting us
The contact page provides the publisher's email address when configured. Email links open your own email application; this website does not submit a contact form. If you email us, your email provider and the publisher's provider process that correspondence. Send only information needed to explain your question or correction. Do not send medical records, participant data, or urgent health concerns.
For privacy questions or requests about correspondence you have sent, use the same contact channel. The publisher may need to verify the request before changing or deleting records.
External links and updates
Linked websites have their own privacy policies. This notice should be updated before introducing new collection practices or external services.
