This site, like many others, stores small files (called ‘cookies’) on your computer to collect information about how you use the site.

We track the number of visitors to the site using Google Analytics. However we do not send any personal information about you to Google Analytics.

We anonymise your IP address before it’s sent to the Google Analytics servers, so there’s no way to identify which computer visited the site.

We also set the main Google Analytics cookie (_ga) to expire at the end of your browsing session, rather than the default 2 years – this means we do not track whether you’ve visited the site before.
