We collect no personal information about you without your knowledge when you visit this site, although you may choose to provide this information to us in specific instances. However, we do collect and store certain information automatically.

Information Collected and Stored Information

When you browse, read pages, or download information in the domain, we automatically gather and store certain technical information about your visit. This information never identifies who you are. The information we collect and store about your visit includes

  • the Internet Protocol (IP) address of the domain from which you access the internet (e.g., 123.456.789.012), whether yours individually or provided as a proxy by your Internet Service Provider (ISP)

  • the date and time you access our site
  • the pages you visit (recorded by the text and graphics files that compose that page); and
  • the internet address of the website from which you linked directly to our site.

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.

This information is NOT shared with anyone beyond the support staff for this website, except when required by computer security, law enforcement investigation or other authorized legal purpose, and is customarily used only as a source of anonymous statistical information.


Websites in the domain use only non-persistent (per-session) cookies to aid users in setting browsing or navigation preferences. These cookies do not collect personal information on users and are erased as soon as you leave our website.

If You Send Us Personal Information

If you choose to provide us with personal information—such as, filling out and submitting a contact us or registration form—that information will be used only to complete the activity for which it was provided, whether it is a one-time event (e.g., returning the results from a web search, forwarding an email message, or registering for a conference), or a recurring event, like providing a subscription service. This information may be used for the technical support of the website and its computer system, or to enhance, evaluate, or otherwise review the website or service.  The information may also be used to contact an individual in response to a request for information.

You may choose to provide us with personal information, for example an e-mail message containing your comments or questions. We use this information to improve our service to you or to respond to your request. There are times when your message is forwarded, as e-mail, to other employees who may be better able to help you.

Personal information, collected as noted herein, is retained to meet the needs of the stated purpose and is then discarded at the earliest time possible.
