A cookie is small piece of data sent by a website that is stored in a web browser while the user browsers the site. They are often used to help you log in to a site more quickly, remember your preferences on a site or save the items in your shopping basket on a retail site. Cookies can also be used to store username and password details, as well as other personal information.
There is an option under the ‘Privacy’ heading that will show which sites have collected cookies and give options for removing them.
Many sites will prompt you on the first visit if you want to accept cookies and in most cases it is fine to do so if you wish. Encourage younger children to always ask an adult first before clicking on an ‘Accept’ or ‘OK’ button on a website as sites may display other messages or disclaimers that require a response.
