How NIH Collects Information
NIH.gov uses Google Analytics to collect the information in the bulleted list in the Types of Information Collected section above. Google Analytics gathers information automatically and continuously. No Personally Identifiable Information (PII) is collected. NIH staff conducts analyses and reports on the aggregated data from Google Analytics and those reports are only available to NIH.gov managers, members of the NIH.gov communications and web teams, and other designated staff who require this information to perform their duties.
Additionally, NIH.gov participates in the Digital Analytics Program (DAP), in which Google Analytics data is collected from websites across the Federal Government. For more information on DAP, please visit the .
NIH also uses online surveys to collect opinions and feedback from a random sample of visitors. NIH.gov uses the ForeSee Results’ American Customer Satisfaction Index (ACSI) online survey to obtain feedback and data on visitors’ satisfaction with the NIH.gov website. This survey does not collect PII. Although the survey invitation pops up for a random sample of visitors, it is optional. If you decline the survey, you will still have access to the identical information and resources at the NIH.gov site as those who do not take the survey. The survey reports are available only to NIH.gov managers, members of the NIH.gov Communications and Web Teams, and other designated staff who require this information to perform their duties.
NIH retains the data from Google Analytics, and ACSI survey results as long as needed to support the mission of the NIH.gov website.
How NIH Uses Cookies
The Office of Management and Budget Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies allows Federal agencies to use session and persistent cookies.
When you visit any Web site, its server may generate a piece of text known as a "cookie" to place on your computer. The cookie allows the server to "remember" specific information about your visit while you are connected.

Persistent Cookies
We use persistent cookies to enable Webtrends and Google Analytics to differentiate between new and returning NIH.gov visitors. Persistent cookies remain on your computer between visits to NIH.gov until they expire. We also use persistent cookies to block repeated invitations to take the ACSI survey. The persistent cookies that block repeated survey invitations expire in 90 days. The OMB Memo 10-22 Guidance defines our use of persistent cookies as "Usage Tier 2 — Multi-session without Personally Identifiable Information (PII).†The policy says, "This tier encompasses any use of multi-session Web measurement and customization technologies when no PII is collected."

How NIH.gov uses Third-Party Web sites and Applications
As part of the OMB Memo M-10-06, Open Government Directive, the NIH uses a variety of new technologies and social media options to communicate and interact with citizens. These sites and applications include popular social networking and media sites, open source software communities and more. TPWAs are Web-based technologies that are not exclusively operated or controlled by NIH, such as applications not hosted on a.gov domain or those that are embedded on NIH Web pages. Users of TPWAs often share information with the general public, user community, and/or the third-party operating the Web site. These actors may use this information in a variety of ways. TPWAs could cause PII to become available or accessible to NIH and the public, regardless of whether the information is explicitly solicited or collected by NIH.
The following list includes some of the TPWAs we use and their purpose. NIH sometimes collects and uses PII made available through third-party Web sites. However, we do not share PII made available through third-party Web sites. Your activity on the third-party Web sites we use is governed by the security and privacy policy of those sites, which we have linked below. 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. Therefore, you should also adjust privacy settings on your account to match your preferences.
For any NIH TPWA that collects PII, the list below also includes details on the information NIH collects and how we will protect your private information.
