Cookies are small pieces of data that websites store in your browser in order to remember your personal settings – eg: stuff like whether you are logged in, or which items you just added to your shopping basket. They're mostly used to speed up your browsing experience. Without them, you would probably get really bored of filling in the same information repeatedly or waiting for a page to reload.
Cookies are anonymous. They use a randomly generated number to identify themselves and contain no information that could personally identify you.
You can disable any cookies already stored on your computer, but these may stop our website from functioning properly.
