How NIH.gov uses Third-Party Web sites and Applications

You should review the third-party privacy policies before using the sites and ensure that you understand how your information may be used. If you have an account with a third-party Web site, and choose to follow, like, friend, or comment, certain PII associated with your account may be made available to NIH based on the privacy policy of the third-party Web site and your privacy settings within that third-party Web site.
