Cookies are designed to remember things that you have done on a website in the past, which can include putting products in your basket, logging in, or clicking on links. This can save you time when you visit a website more than once.
Cookies can be used by websites in many ways:
- To remember your preferences

Persistent cookies are cookies that are stored on your computer’s memory and not deleted when the browser is closed. They are used to remember your preferences for the website for next time you visit. They are also used to collect information about the numbers of visitors, the average time spent on a particular page and analyse shopping behaviour on the website. We use this information to find out how the well the website works and where it can be improved.
Flash Cookies (or Locally Shared Objects)
You probably have Adobe Flash installed on your computer. Websites that contain Flash can also store small files on your computer that are used in the same way as cookies.
Flash cookies can back up the data that is stored in other cookies. When you delete cookies, your Flash cookies are not affected, which means that a website may still recognise you if it backed up the deleted cookie information on a Flash cookie.
