What is a cookie?
A cookie is a harmless text file that is stored in your browser when you visit almost any website. The purpose of the cookie is for the website to be able to remember your visit when you browse that page again. Although many people do not know it, cookies have been used for 20 years, since the first web browsers for the World Wide Web appeared.
What is NOT a cookie?
It is not a virus, Trojan, worm, spam, spyware, or pop-up window opener.
What information does a cookie store?
Cookies do not usually store sensitive information about you, such as credit cards or banking data, photographs, your ID, or personal information, etc. The data they store is technical in nature, personal preferences, content personalization, etc.
The web server does not associate you as a person but rather your web browser. In fact, if you regularly browse with Internet Explorer and try to browse the same website with Firefox or Chrome, you will see that the website does not recognize you as the same person because it is actually associating with the browser, not the person.
What types of cookies exist?
Technical Cookies: These are the most basic and allow, among other things, to know when a human is browsing or an automated application, when an anonymous user and a registered user are browsing, basic tasks for the operation of any dynamic website.
Analytical Cookies: They collect information about the type of browsing you are doing, the sections you use the most, products consulted, usage time, language, etc.
Advertising Cookies: Display advertising based on your browsing, country of origin, language, etc.
What are first-party and third-party cookies?
First-party cookies are generated by the page you are visiting, and third-party cookies are generated by external services or providers such as Facebook, Google, etc.
