Privacy and Security
General Information
The National Cancer Institute (NCI) respects the privacy of users of its website, cgems.cancer.gov. NCI does not disclose, give, sell, or transfer any personal information about visitors to cgems.cancer.gov unless required to do so by law.
NCI is especially concerned about protecting the privacy of children. NCI encourages parents and teachers to stay involved and in control of children's Internet explorations. It is particularly important for parents to offer guidance to their children about providing personal information online.
NCI automatically collects a limited amount of information about the use of its website, primarily for statistical purposes (that is, to measure the numbers of visitors to various sections of the site). This information may also be helpful when considering changes to cgems.cancer.gov, to make the site more useful to visitors.
Information Collected and Stored Automatically
The following information about users of the NCI website is collected and stored automatically:
- The Internet domain from which a user has accessed the Internet. For example, if a user connects to the Internet through America Online, the domain is aol.com.
- The Internet protocol (IP) address of the computer that was used to access the Internet. An IP address is a number that is assigned to a user's computer when he/she logs onto the Internet. When a Web page is requested, the user's IP address is included in the message, and the recipient of the request can respond to it by sending another message using that IP address.
- The name and version of the user's computer operating system and Internet browser. For example, Windows 2000 (operating system) and Internet Explorer 6.0 or Netscape Navigator 7.1 (Internet browsers).
- If a user comes to cgems.cancer.gov from another website, the Internet address of the "referring" website.
- The date, time, and duration of the user's visit to cgems.cancer.gov, and the pages visited.
Cookies
When a user visits a website, the website's server generates a piece of information known as a "cookie" and places it on the user's computer. Some cookies remain on a user's computer after the user has ended his/her website visit. These types of cookies are called "persistent" cookies. They collect personal information about a user and allow the user's computer to be recognized in the future.
The NCI website, however, generates only non-persistent cookies, or "session cookies." These cookies are erased by a user's Internet browser after a period of inactivity or when the user closes his/her browser. Session cookies do not collect any personal information about a user.
Session cookies serve technical purposes, such as allowing seamless navigation through a website. They are stored in memory and are only available during an active browser session.
Email Messages Sent to the NCI Website
When inquiries are sent to the NCI website by email, the question(s) and the email address of the sender are stored electronically to allow time for a response to be researched, written, and sent. Unless otherwise required by law, NCI will not identify anyone who sends questions or comments to its website. NCI does not collect information that will allow users to be identified personally, unless they choose to provide such information.
If children send questions or comments to the NCI website and include their name and/or home mailing address as part of their message, the information will be used only to respond to them personally. Providing this type of information is optional, and NCI suggests that children obtain their parents' permission before providing any information online – to the NCI website or any other website.
