We collect no personal information about you when you visit this Web site, unless otherwise stated or unless you choose to provide this information to us. However, we collect and store certain information automatically. What we collect and store automatically is:
--The Internet Protocol (IP) address for the domain from which you access the Internet (e.g., 123.456.789.012255.255.255.0) whether the domain is yours individually or is provided as a proxy by your Internet Service Provider (ISP)
--The date and time you access our site
--The pages you access (recorded by the text and graphics files that compose that page)
--And, the Internet address of the Web site from which you linked directly to our site.
--The type of brower and operating system used to access our site.
Similar information may be gathered for anonymous ftp, remote account login, or other comparable types of connections.
We use the summary statistics to help us make our site more useful to visitors, such as assessing what information is of most and least interest to visitors, and for other purposes such as determining the site's technical design specifications and identifying system performance or problem areas.
JPL will protect all such information consistent with applicable law.
Comments Sent by E-mail
You may choose to provide us with personal information, as in an e-mail containing your comments or questions. We use this information to improve our service to you or to respond to your request. There may be times when your message is forwarded, as e-mail, to other JPL employees who may be better able to help you. We normally do not share our e-mail with any other outside organizations, unless determined necessary for security purposes or when required by law. Remember that e-mail is not necessarily secure against interception. If your communication is sensitive, or includes personal information, you might want to send it by postal mail instead.
