A "cookie" is a small text file that’s stored on your computer, tablet or phone when you visit a website. A cookie will contain some anonymous information such as a unique identifier and the site name and some digits and numbers.
Some cookies are deleted when you close down your browser. These are known as session cookies. Others remain on your device until they expire or you delete them from your cache. These are called persistent cookies and they enable us to remember things about you as a returning visitor.

2. What to do if you don’t want cookies to be set
Some people find the idea of a website storing information on their computer or mobile device intrusive, particularly when this information is stored and used by a third party without them knowing. For example, you may not want to see advertising that has been targeted to your interests. If you prefer, it is possible to block cookies, by changing a setting within your browser that allows you to refuse the setting of all or some cookies, or to delete cookies that have already been set. However, if you use your browser settings to block all cookies (including essential cookies) you may not be able to access all or parts of the Site.
On this Site, session and persistent cookies are used. The cookies on this Site are used to track visitor behaviour, and this data is used to try and understand what people do and don't like about the Site so it can be improved. This practice is known as “website analytics”. Since Google started providing its own analytics technology free of charge to website owners, almost all websites use some form of it - although there are also paid for services available to rival Google's.
Analytics cookies are probably the most common form of cookies in use today.
