Privacy Policy & Disclaimers

The Surveillance Research Program (SRP) respects the privacy of visitors to our websites. The US Department of Health and Human Services, and the National Cancer Institute, of which SRP is a part, do not disclose, give, sell, or transfer any personal information about your visit unless required by law to do so.

When inquiries are mailed to us, we store the question and the e-mail address information so that we can respond electronically. Unless otherwise required by statute, we do not identify anyone who sends questions or comments to our website. We will not obtain any information that will allow us to personally identify you when you visit our site, unless you chose to provide such information to us.

Use of Analytic Tools to Collect Information

When you browse through any website, certain information about your visit can be collected. SRP uses analytics tools to collect information automatically and continuously. We use this information to measure the number of visitors to our websites and its various sections and to distinguish between new and returning visitors to help make our site more useful to visitors. No personally identifiable information (PII) is collected via this tool.

The SRP staff conducts analyses and reports on the aggregated data from these analytics tools. The reports are only available to SRP website managers, members of their communications and web teams, and other designated staff who require this information to perform their duties.

SRP and DCCPS retains the data from analytics tools only as long as required by law or needed to support the mission of the SRP and DCCPS websites.

How SRP Uses Cookies

The Office of Management and Budget (OMB) Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies [PDF - 102 KB] allows Federal agencies to use session and persistent cookies.

When you visit any website, 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. The cookie makes it easier for you to use the dynamic features of web pages. Requests to send cookies from EGRP's web pages are designed to collect information about your browser session only; they do not collect personal information about you.

There are two types of cookies, single session (temporary) and multi-session (persistent). Session cookies last only as long as your web browser is open. Once you close your browser, the cookie disappears. Persistent cookies are stored on your computer for longer periods.

How are temporary "Session Cookies" used?

We use session cookies for technical purposes such as improving navigation through our site. These cookies let our server know that you are continuing a visit to our site. The "session" cookie is not permanently stored on your computer. The cookie and the information about your visit are automatically destroyed shortly after you close your browser to end the session.

The OMB Memo 10-22 Guidance defines our use of session cookies as "Usage Tier 1-Single Session." The policy says, "This tier encompasses any use of single session web measurement and customization technologies."

How are "Persistent Cookies" used?

The OMB Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies [PDF - 102 KB] allows Federal agencies to use persistent cookies in addition to temporary session cookies.

We use persistent cookies to help us recognize new and returning visitors to the GIS website. Persistent cookies remain on your computer between visits to the GIS website until they expire. We do not use this technology to identify you or any other individual site visitor. SRP uses persistent cookies to enable analytics tools to measure how new and returning visitors use the GIS website over time.

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 to opt out or disable cookies

If you do not wish to have session or persistent cookies placed on your computer, you can disable them using your web browser. If you opt out of cookies, you will still have access to all information and resources the GIS website provides.

Instructions for disabling or opting out of cookies in the most popular browsers are located at Please note that by following the instructions to opt out of cookies, you will disable cookies from all sources, not just those from the GIS website.
