Measuring website usage

We collect logs on our servers that tell us how people use this site. We do this to make sure it’s meeting your needs and to understand how we could do it better. Cookies are used to give us more information in these logs.

The logs are analysed to tell us what pages you visit, how long you are on the site, how you got here and what you click on. We do not collect or store your personal information (eg your name or address) so this information cannot be used to identify who you are.
