More information about cookies


A cookie is a harmless text file that is stored on your browser when you visit almost any website. Cookies help the website remember your visit when you browse that page again. Although many people are unaware of this, cookies have been in use for 20 years, since the first web browsers appeared on the World Wide Web.


It’s not a virus, or a Trojan, or a worm, or spam, or spyware, and it doesn’t open pop-up windows.


Cookies do not usually store sensitive information about you, such as credit cards or bank data, photos, your ID number or personal information, etc. The data they save are of a technical nature, personal preferences, content personalization, etc.

The web server does not associate it to you as a person but to your web browser. In fact, if you normally browse with Internet Explorer and try browsing the same website with Firefox or Chrome, you will see that the web does not realize that you are the same person, because in fact it is associating it with the browser, not the person.


  • Technical cookies: These are the most basic and allow, among other things, to know whether a human or a bot are browsing, whether an anonymous or a registered user is browsing, and basic tasks for the operation of any dynamic website.
  • Analytics cookies: These gather information about the type of browsing, sections more visited, products looked up, time of use, language, etc.
  • Advertising cookies: These show ads based on your browsing, your country of origin, your language, etc.


First-party cookies are those generated by the website you are visiting and third-party cookies are those generated by external services or providers, like Facebook, Twitter, Google, etc.


So you can understand the effect that disabling cookies may have, below are some examples:

  • You won’t be able to share contents from that website on Facebook, Twitter or any other social network.
  • The website won’t be able to adapt its contents to your personal preferences, like online stores do.
  • You won’t be able to access your personal area of the website, like for instance, My account, or My profile or My orders.
  • Online stores: It will be impossible to shop in online stores, having to call by phone or physically visit the store instead, if it is available.
  • You won’t be able to personalize your geographical preferences, such as time zone, currency or language.
  • The website won’t be able to make web analysis on web visitors and traffic, which will make the web less competitive.
  • You won’t be able to write on the blog, upload photos, publish comments, value or score content. The web won’t know whether you are a human or a bot that publishes spam.
  • It will not be possible to show targeted ads, which will reduce website advertising revenues.
  • All social networks use cookies: if you disable them, you won’t be able to use any social network.
