NASA's Web Privacy Policy

This notice provides NASA's policy regarding the nature, purpose, use and sharing of any information collected via this Web site. The information you provide on a NASA Web site will be used only for its intended purpose. We will protect your information consistent with the principles of the Privacy Act, the e-Government act of 2002, the Federal Records Act, and as applicable, the Freedom of Information Act.

Submitting information is strictly voluntary. By doing so, you are giving NASA your permission to use the information for the intended purpose. If you do not want to give NASA permission to use your information, simply do not provide it. However, not providing certain information may result in NASA's inability to provide you with the information or services you desire.

There are several types of information we collect. These include:

NASA never collects information for commercial marketing. We will only share your information with another government agency if it relates to that agency, or as otherwise required by law. NASA never creates individual profiles or gives your information to any private organization.

Automatically Collected Information

We collect and temporarily store certain technical information about your visit for use in site management and security purposes. This information includes:

Information Collected for Tracking and Customization (Cookies)

A cookie is a small file that a Web site transfers to your computer to allow it to remember specific information about your session while you are connected. Your computer will only share the information in the cookie with the Web site that provided it, and no other Web site can request it. There are two types of cookies, session and persistent. Session cookies last only as long as your Web browser is open. Once you close your browser, the cookie disappears. Persistent cookies store information on your computer for longer periods of time.

NASA Web sites may use session cookies for technical purposes such as to enable better navigation through the site, or to allow you to customize your preferences for interacting with the site. A few NASA Web sites may also make use of persistent cookies to remember you between visits so, for example, you can save your customized preference settings for future visits. Each NASA site using persistent cookies identifies itself as doing so.

At no time is your private information, whether stored in persistent cookies or elsewhere, shared with third parties who have no right to that information. If you do not wish to have session or persistent cookies stored on your machine, you can turn them off in your browser. However, this may affect the functioning of some NASA Web sites.

Personal Information

If you choose to provide us with personal information, through such methods as completing a form or sending us an email, we will use that information to respond to your message and to help us get you the information or services you have requested.

Remember that email isn't necessarily secure. You should never send sensitive or personal information like your Social Security number in an email. Use postal mail or secure Web sites instead.

Some of our Web sites ask visitors who request specific information to fill out a registration form. For example, vendors looking for marketing opportunities by visiting our NASA Acquisition Internet Service site may be asked to register to obtain email notices of business opportunities. Other information collected at Web sites through questionnaires, feedback forms, or other means, enables us to determine visitors' interests, with the goal of providing better service to our customers.
