Welcome to the SLAC National Accelerator Laboratory website. We collect no personal information about you when you visit our website unless otherwise stated or unless you choose to provide this information to us. However, we collect and store certain information automatically:

• Internet Protocol (IP) address of the domain from which you access the Internet (i.e., 123.456.789.012), either your individual address or the proxy provided by your Internet Service Provider (ISP).
• Date and time you access our site.
• Pages you view (recorded by the text and graphics files that compose that page).
• Web address of the site from which you linked directly to our site.
• Browser version and operating system of the computer you are using.

This information is not shared with anyone beyond the website support staff, except when required by law enforcement investigation or contract, and is used only as a source of anonymous statistical information.

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.

Parts of our site - pages used by our staff, users, and collaborators - may use cookies. A cookie contains information that is either stored in your computer's memory, or in a file on your computer's hard disk. Cookies that are stored in your computer's memory are automatically removed when you quit your browser. Cookies that are stored in a file on your computer's hard disk will have an expiration date after which time they will no longer be valid. Most modern web browsers allow you to control cookie use by enabling, disabling, or prompting when a cookie is encountered.

You may choose to provide us with personal information, by sending email with questions or comments or by filling out an online form and submitting it to us through our website. We use this information to:

• Respond to your message.
• Gather the requested information, such as to attend a SLAC hosted conference.

We do not create individual profiles with the information you provide. If information is collected, it will be used solely in connection with SLAC or for such other purposes as are described at the point of collection. We do not give, sell, or transfer any personal information to a third party.

However, your email message, question, or comment may be forwarded to other SLAC employees who may be better able to help you. Except for authorized law enforcement investigations, we do not share our email with any other outside organizations. However, email and online forms are not secure against interception and senders cannot expect privacy. If you are concerned about transmitting personal information such as bank account, charge card, or social security numbers, contact the web page owner for an alternative method to provide the necessary information.
