What are cookies?
Cookies are small text files which are downloaded to a user’s computer or mobile device when a browser is used to visit a website. Some cookies (known as sessional cookies) are created temporarily and are deleted when a user leaves a particular website. Other cookies (known as persistent cookies) allow the user’s device to be recognised by the originating website on subsequent visits to that website.
Cookies are used to perform many different roles. For example, they can be used to enable users to navigate between pages efficiently, remember their preferences, and manage log-ins and can be used to generally improve the user experience. They can also help to ensure that adverts displayed online are more relevant to users and their interests.
As cookies themselves include very little information they cannot be used by themselves to identify individual users and cannot usually be used to reveal personally identifiable information.
