What is a cookie?

A cookie is a harmless text file that is stored in your browser when you visit almost any Web page. The cookie’s usefulness is that the web will be able to remember your visit when you browse that page again. Although many people do not know the cookies have been used for 20 years, when the first browsers appeared for the World Wide Web.

What is NOT a cookie?

It is not a virus, nor a trojan, nor a worm, nor spam, nor spyware, nor does it open pop-up windows.

What information does a cookie store?

Cookies do not usually store sensitive information about you, such as credit cards or bank details, photographs, your DNI or personal information, etc. The data they keep are of technical character, personal preferences, personalization of contents, etc.

The Web server does not associate you as a person if not your Web browser. In fact, if you usually navigate with Internet Explorer and try to navigate the same web with Firefox or Chrome you will see that the web does not realize that you are the same person because you are actually associating the browser, not the person.

What kind of cookies exist?


  • Technical Cookies : They are the most elementary and allow, among other things, to know when you are browsing a human or an automated application, when you navigate an anonymous user and one registered, basic tasks for the operation of any dynamic web.
  • Analysis Cookies : Collect information about the type of navigation you are making, the sections you use most, products consulted, time zone of use, language, etc.
  • Advertising Cookies : They show publicity depending on their browsing, their country of origin, language, etc.

What are your own and third party cookies ?

Your own cookies are those generated by the page you are visiting and those of third parties are those generated by external services or suppliers like Facebook, Twitter, Google, etc.

What happens if I deactivate cookies?

To understand the scope that can disable cookies We show some examples:

  • You won’t be able to share the contents of that web on Facebook, Twitter or any other social media.
  • The website won’t be able to adapt its content to your personal preferences as generally happens with online stores.
  • You will not be able to access the personal area of that website, such as my account, or my profile or my orders.
  • Online stores: It will be impossible for you to shop online: you will have to telephone or visit the actual shop, if there is one.
  • You will not be able to customize your geographic preferences as a time slot, currency or language.
  • The website will not be able to carry out analysis of its visitors and traffic, which makes it harder for the website to be competitive.
  • You will not be able to write on the blog, upload photos, publish comments and review or rate content. The web will also not know if you are a human or an automated application that publishes spam.
  • It will not be able to show trade-specific advertising, which then reduces the website’s advertising revenue.
  • All social networks use cookies, if you disable them you will not be able to use any social network.
