More information about cookies

What is a cookie?

A cookie is an inoffensive text file that is stored on your browser when you visit almost any web page. The use of the cookie is that the website is able to remember you when you revisit it. Although many people do not know this, cookies have been used for the last twenty years. They were first used when the first browsers for the World Wide Web appeared.

What isn’t a cookie?

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

What information does a cookie store?

Cookies don’t usually store sensitive information about you, such as credit card or bank details, photos, your ID card number or personal information, etc. The data that is stored in cookies is usually technical data, personal preferences, content personalisation, etc.
The web server does not recognise you as a person, but does recognise your web browser. In fact, if you usually use Internet Explorer and you try to use the same website with Firefox or Chrome you will see that the website does not realise that you are the same person, because in reality it is recognising the browser, not the person.

What types of cookies exist?

• Technical cookies: These are the most elementary cookies and they allow the website to know, among other things, who is browsing the website: whether it’s a human or an automated application, or whether it’s an anonymous user or a registered user, which are basic tasks for the correct function of any dynamic website.
• Analysis cookies: These cookies collect information about the type of browsing that is being carried out, the sections that you use the most, the products consulted, the time of use, language, etc.
• Advertising cookies: These cookies show advertisements based on your browsing, your country of origin, language, etc.

What are first party cookies and third party cookies?

First party cookies are generated by the website that you are visiting and third party cookies are generated by external services or providers such as Facebook, Twitter, Google, etc.

What happens if I disable cookies?

To better understand the effect that disabling cookies can have we can show you some examples:

• You will not be able to share content from that website on Facebook, Twitter or any other social network.
• The website will not be able to adapt its content to your personal preferences, which is usually what happens on online stores.
• You will not be able to access the personal section of that website, like for example My account, or My profile or My orders.
• Online stores: It will be impossible for you to carry out online purchases; these purchases would have to be made via telephone or by visiting the physical store if there is one.
• It will not be possible to personalise your geographical preferences such as time zone, currency or language.
• The website will not be able to carry out analyses about visitors and web traffic; this will make it more difficult for the website to be competitive.
• You will not be able to write on the blog, nor upload photos, publish comments, review or rate content. In addition, the website will not know if you are a human or an automated application that posts spam.
• It will not be possible to show selected advertising, this will reduce the advertising income of the website.
• All social networks use cookies; if you disable them you will not be able to use any social network.
