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 usefulness of the cookie is that the website is able to remember your visit when you browse that page again. Although many people are not aware of this, cookies have been used for the past 20 years, when the first browsers for the World Wide Web appeared.

What is a cookie NOT?

It is not a virus, nor a Trojan, nor a worm, nor spam, nor spyware, and it does not open pop-ups.

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 or personal information, etc. The data they hold are of a technical nature, personal preferences, personalisation of content, etc.

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

What kind of cookies are there?

– Technical cookies: These are the most basic and make it possible, among other things, to know when a human or an automated application is browsing, or when an anonymous and registered user is browsing, basic tasks to operate any dynamic website.

– Analysis cookies: They collect information on the type of browsing you are doing, the sections you use most, products consulted, time band during use, language, etc.

– Advertising cookies: They show advertising based on your browsing, country of origin, language, etc.

What is the difference between your own cookies 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 providers such as Mailchimp, Mailrelay, Facebook, Twitter, Google, etc.

Can cookies be deleted?

Yes. Not only deleted, but also blocked, in a general way or in particular for a specific domain.

To delete cookies from a website you must go to your browser settings where you can search the cookies associated with the domain in question and proceed to delete them.

Important notice about cookies

 Bearing in mind the way in which the Internet and websites work, we do not always have information on the cookies that third parties can use through our website.
