Measuring site usage

We use Google Analytics and Google Optimize software to collect information about how you use We do this to help make sure the site is meeting your needs and to help us make improvements.

We store information about:

  • the pages you visit and how long you spend on each page
  • how you got to
  • what you click on while you're visiting
  • which variation of a page you've visited when we are testing out small design changes using Google Optimize

Any information on site usage is received in a way that we can't identify individuals. For example, we never receive your name or address.

We don't make any attempt to find out the identities of people visiting and we don't allow Google to do this either.

All information we get through cookies and analytics will be treated in confidence. We will never sell, trade or give your details to third parties, unless we're required to do it by law.
