Our website uses Google Analytics Cookies to measure how it is used. The information collected cannot be used to identify you; the system uses cookies to build aggregated data such as the numbers of pages that visitors read, the numbers of visits referred by each major search engine and to distinguish between new visits and repeat visits. This website does not use any other cookies.

Google Analytics code uses first-party cookies to:

  • Determine which domain to measure
  • Distinguish unique users
  • Remember the number and time of previous visits
  • Remember traffic source information
  • Determine the start and end of a session
  • Remember the value of visitor-level custom variables

Google Analytics sets the following cookies
