What are Cookies?
Cookies are small text files created on your hard disk by your web browser when using a particular website so that the website can pick up that information (which is usually encrypted) again at later time – perhaps in a different section of the site. A website could be serving thousands of users at the same time and has no way of remembering who the requests are coming from without storing some form unique identifier in cookies as you browse from page to page. For example, trying to shop online and losing each item from your basket when you look at another item would not be an acceptable user experience.
The are two types of cookies:
Session Cookies only remain on your hard disk whilst you are using the website – until you close the web browser. These are temporary but can be vital to the correct functioning of the website.
Persistent Cookies can remain on your hard disk as long as specified by the website (unless you remove them). They are usually used for tracking usage of the website – measuring if and how often people return etc., and for remembering your preferences – some websites for example, will remember your first name in order to give you a personalised greeting.
NO PERSONALLY IDENTIFIABLE INFORMATION IS STORED IN OUR COOKIES.
