More information about cookies

What does a cookie do?

A cookie is a harmless text file that is stored on your browser when you visit almost any website. Cookies are used so that the website is able to remember your visit when you browse on that website again. Though many people may not realise, cookies have been used for the past 20 years, when the very first World Wide Web browsers appeared.

What does a cookie not do?

It is not a virus, a Trojan, or a worm. It is not spam or spyware, and does not 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 ID number or personal information, etc. The information it does store is technical, personal preferences, contents customisation, etc.

The website server does not connect to you as a person, rather your website browser. In fact, if you regularly browse with Internet Explorer and try to browse on the same website with Firefox or Chrome, you will see that the website does not know that you are the same person because in reality it is linked to the browser, not to the individual.

What kinds of cookies are there?

Technical Cookies: These are more elementary and allow, among other things, the device to know when it is a human or machine browsing, when an anonymous or registered user is browsing, as well as basic tasks for the operation of any dynamic website.

Analysis Cookies: These collect information about the type of browsing that is taking place, the most used sections, products looked at, usage time band, language, etc.

Advertising Cookies: They show advertising based on your browsing habits, country, language, etc.

What are own and third party cookies?

Own cookies are those generated by the website you are visiting, and third party cookies are those generated by external services or suppliers, such as Facebook, Twitter, Google, etc.

What happens if i disable cookies?

Here are some examples of what can happen if you disable cookies:

  • You will not be able to share contents of that website on Facebook, Twitter, or any other social network.
  • The website will not be able to adapt contents to your personal preferences, which is what usually happens on online stores.
  • You will not be able to access the personal area on that website, such as My account, My profile or My orders.
  • Online stores: You will not be able to make online purchases; they will have to be made over the phone or by visiting the physical store in person if there is one.
  • It will not be possible to customise your geographic preferences, time band, currency or language.
  • The website will not be able to carry out web analytics about website visitors and traffic, which will make it harder for the website to be competitive.
  • You will not be able to write on the blog, upload photos, publish comments, assess or grade contents. The website will not know whether you are human or an automated application that publishes spam.
  • It will not be able to display sector-specific publicity, thus reducing the website’s advertising income.

 

  • All social networks use cookies. If you disable them you will not be able to use any of the social networks.

Can cookies be deleted?
