More information on cookies

What is a cookie?

A cookie is an inoffensive text file stored in your browser when you visit almost any website. It is used so the site can remember your visit when you browse it again. Many people don’t know it but cookies have been in use for the past 20 years, ever since the first World Wide Web browsers appeared.


What is a cookie NOT?

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


What information does a cookie store?

Cookies do not usually store sensitive information about you, such as credit card or bank details, photos, your ID document or personal information, etc. The data that is saved is technical in nature and includes personal preferences, content personalization, etc.

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


What type of cookies exist?

Technical cookies. These are the most elemental ones and make it possible to know, among other things, how a person or an automated app is browsing and when an anonymous or registered user is browsing, i.e., basic tasks for operating any web dynamic.

Analysis cookies: These collect information on the type of browsing being done, the sections most commonly used, products consulted, use time range, language, etc.

Advertising cookies: These display advertising according to your browsing habits, the country you log in from, language, etc.

What are own and third-party cookies?

Own cookies are generated by the site you are visiting, while third-party cookies are generated by external services or providers such as Facebook, Twitter, Google, etc.

What happens if I disable cookies?

Below are a number of examples of the impact that disabling cookies can have:

  • You won’t be able to share the site content on Facebook, Twitter or any other social network.
  • The site won’t be able to adapt content to your personal preferences, as usually happens with online stores.
  • You won’t be able to access the site’s personal area, such as, for example, My Account, My Profile or My Orders.
  • Online stores: You won’t be able to make online purchases and will have to place orders over the phone or visit the physical store if there is one.
  • You won’t be able to personalize your geographic preferences such as time range, currency or language.
  • The site won’t be able to perform web analytics on site visitors and traffic, making it hard for it to be competitive.
  • You won’t be able to write on the blog or upload photos, publish comments, assess or score content. The site won’t know whether you are a person or an automated app publishing spam.
  • It won’t be able to display sector-specific advertising, reducing site advertising revenue.
  • All social networks use cookies. If you disable them you won’t be able to use any social network.
