About cookies

Most websites use small text files called “cookies” which are uploaded and stored on your computer. Storing these files is referred to as “setting a cookie”. Websites then read information back from these cookies.

They are used for things like setting user preferences and accessibility options, keeping track of log-ins, comments and online shopping baskets. They are also often used to gathering statistical information for the website owner and to send anonymous tracking data to advertisers and search engines.

Although most cookies are used for legitimate purposes, a website could set cookies to inappropriately track your web browsing or steal identifying data. Also, a legitimate cookie carrying identifying data (eg a log-in) can be vulnerable to being intercepted if it is not properly encrypted.

Web browsers (eg Firefox, Internet Explorer, Safari, Chrome) can be set to manage cookies on your computer. See your web browser’s help section for details.
