What are Cookies?

Cookies are small data files that a website asks your browser to store on your computer or mobile device when you visit the website or certain pages. The cookies allow the website to 'remember' your actions or preferences over time. Most browsers accept cookies, but users can set their browsers to block or delete these cookies whenever they wish.

Cookies usually contain the name of the website the cookie came from, how long the cookie will remain on your device, and a value, which is usually a randomly generated unique number.

Some cookies will be deleted as soon as you leave the website (so-called 'session cookies'), other cookies will remain on your computer or mobile device and will help us to identify you as a visitor to our website (so-called 'persistent cookies' ).
