What is a cookie?
Cookies are small text files that are stored on the User's computer when they visit almost any website. Cookies are very useful for remembering a User's visit when they browse this website again. Many people don't know that cookies started to be used 20 years ago, when the first browsers appeared on the World Wide Web.
What a cookie IS NOT
It isn't a virus, or a Trojan, or a worm, or spam, or spyware, nor can it open pop-up windows.
What information does a cookie store?
Cookies do not usually store sensitive information about the User, such as credit card or banking details, photographs, ID document or personal information, etc. The data stored are technical, personal preferences, content personalisation, etc.
The web server does not associate the User as a person, but rather their web browser. In fact, if a User browses habitually with Internet Explorer and attempts to browse the same website with Firefox or Chrome, they will not register that the User is the same person because in reality it is associating with the browser, not the person.
What types of cookies are there?
- Technical cookies: they are the most elementary and allow, among other things, to know whether a human or an automated application is browsing, or when an anonymous user or a registered one are browsing, which are basic tasks for the operation of any dynamic website.
- Analytical cookies: they collect information on the type of navigation that is being performed, the sections most used, products consulted, time zone of use, language, etc.
- Advertising cookies: they display advertising based on a User's browsing, their country of origin, language, etc.
What are first-party and third-party cookies?
First-party cookies are those generated by the website being visited and third-party cookies are those generated by external services or suppliers such as Facebook, Twitter, Google, etc.
What happens if I disable the cookies?
