Types of Information Collected
When you visit the CRAN website (addictionresearch.nih.gov), the following information is stored:
- Domain from which you access the Internet
- IP address (an IP address is a number that is automatically assigned to a computer when surfing the Web)
- Operating system and information about the type of browser used when visiting the site
- Date and time of your visit
- Pages you visited
- Address of the Web site that connected you to the addictionresearch.nih.gov Web site (such as google.com or bing.com)
We use this information to measure the number of visitors to our site and its various sections and to help make our site more useful to visitors. Unless it is specifically stated otherwise, no additional information will be collected about you.
When inquiries are E-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 publicly who sends questions or comments to our web site. We will not obtain information that will allow us to personally identify you when you visit our site, unless you chose to provide such information to us.
Session cookies are used for technical purposes, such as enabling better navigation through the site, facilitating the use of user accounts, and generating aggregated statistics about how the website is used. There are two types of session cookies:
- Single-session cookies last only as long as a web browser is open. Once the browser is closed, the data files on your computer are deleted. Information collected from per-session cookies will not be disclosed to third parties. For these technical purposes, per-session cookies are enabled by default. Under the framework of OMB M-10-22, this qualifies as a Tier 1 use.
- Multi-session cookies last beyond a single session of browsing a website; this allows a website to recognize a computer or user for defined amount of 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." NIH generally does not access or store the raw information collected through these cookies. We do view aggregate statistical analyses prepared by our third-party analytics provider, but these analyses do not include any personally identifiable information. We do not sell, rent, exchange, or otherwise disclose this information to persons or organizations outside the NIH.
