A cookie is a file which is stored on the hard drive of your computer and which enables the website to recognise your computer (they cannot in themselves be used to identify you). An anonymous identifier is a random string of characters that is used for the same purposes as a cookie on platforms, including certain mobile devices, where cookie technology is not available.

We use Google Analytics to track non-identifying, anonymous website usage statistics, such as pages visited and referring websites, for the purposes of improving our websites; Google Advertiser Features to collect non-identifying, anonymous information for interest-based online advertising; and Google Demographic and Interest Reports to collect non-identifying, anonymous demographic data (such as age, gender and interest group) for reporting on general website visitor trends. We also use KISSmetrics to collect non-identifying, anonymised data for the purpose of measuring website repeat visitors and website effectiveness.
We will never pass any information to Google:
- that Google could use or recognise as personally-identifiable information; or
- that permanently identifies a particular device (such as a mobile phone's unique device identifier if such an identifier cannot be reset).
To opt out of tracking by Google Analytics, we recommend installing https://tools.google.com/dlpage/gaoptout/ on your browser.
