What Non-Personally Identifiable Information Do We Collect?

We collect Non-Personally Identifiable Information that does not by itself identify a specific individual. This information is compiled and analyzed on both a individual and an aggregated basis.

We collect the domain name or Internet Protocol (IP) address in order to continually make improvements to our site and develop pages that follow intuitive navigation and fresh and current content for our site users.

Our website follows standard web server recognition practices where the visitor’s domain name or Internet Protocol (IP) address is automatically recognized.

We collect our Website visitors’ most immediate URL visited, domain types (e.g., .com or .org), the date and time of the visit, the number of visits and orders, the number of visits per browsing session, the server type, the operating system and browser type used to come to the site, the country, state and telephone area code where their servers are located, the pages and page titles of our site that visitors viewed during their visit, whether the visitor’s computer is enabled for Java or cookies, browser language, applications and plug-ins, and search terms entered on our site.

Our Website uses “cookies,” small amounts of information stored in files within your computer’s browser by a particular Website that helps it recognize your browser as a previous visitor and save and remember any preferences that may have been set while your browser was visiting the Site. For example, we may save your login information so you do not have to sign in every time you visit the site. You may set your browser so that it will not accept “cookies;” however, you will be unable to engage in transactions on our Website.

There are “do not track” or similar browser choices available to consumers with respect to online web activity, but given the present lack of consensus of what constitutes an informed election, appropriate trigger or breadth of scope of such choice, our Website will continue to operate as described in this policy, whether or not a “do not track” signal is received.

We also give accessible items from our site as follows:

  • Links

The links on our site will not open in new windows without notifying you.

  • Images

Links that lead away from the company website will open in a new window.

  • Files (downloadable)

Any file that is downloaded will be designated by file type and is a downloadable file.
We do not control the content of external websites which we provide a link to. These websites may have their own privacy practices and policies and we encourage you to review any policy of a third party website before providing them with personal information.

A Special Note About Children

Children are not eligible to use our services, including the Websites, and we ask that minors (under the age of 18) not submit any personal information to us. The Websites are not directed at anyone under 18 and they are not intended to attract anyone under 18. We also do not collect or maintain personally identifiable information from those users who we actually know are under 18. Should we learn or be notified that we have collected information from users under the age of 18, we will immediately delete such personally identifiable information.
