What is a cookie?

Cookies are small text files that are placed on your computer by websites that you visit. They are widely used in order to make websites work, or work more efficiently, as well as to provide information to the owners of the site.

How do cookies work?

A website's cookies store information on your user device, which then gets sent back to that website each time you visit. Sometimes this information is essential to access a website's functions - for example if you need to log in, a cookie will allow the website to recognise your log-in details.
Cookies can also be used to build a profile of your activity on a website - which pages you visit, how long you spend on each page. A website may then use this information to tailor the pages that you see when you visit the site in the future.

How do we use cookies?

We use cookies for two purposes:

  • To track your 'session state' so that when you interact with our website it is able to retrieve data that is specific to you. This allows you to login to our website, for example.
  • To create statistical data about how our visitors find and use our website. This allows us to improve the performance of the website. The information we collect is anonymous, it cannot be used to identify you personally.

A list of the cookies used by this website, and their purpose, is provided below.
