A cookie is a harmless text file that is stored on your browser when you visit almost any website. Cookies enable websites to remember your visit when you return to that page. Although many people are not aware of it, cookies have been in use for 20 years, ever since the first browsers appeared for the World Wide Web.

It is not a virus, a Trojan horse, a worm, spam or spyware and it does not open pop-up windows.

Cookies do not normally store sensitive information about you, such as credit card or bank details, photographs, your ID or personal information, etc. The data stored in them is technical, regarding personal settings and personalisation of content, etc.

The web server does not associate the data with you as a person but with your browser. In fact, if you normally surf the web with Internet Explorer and try to visit the same website with Firefox or Chrome, you will see that the website does not realise that you are the same person, because it is actually making an association with the browser, not the person.
