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 purpose of the cookie is to allow the website to remember your visit when you navigate to that page again. Although many people do not know it, cookies have been used for 20 years, since the first web browsers appeared.
What is NOT a cookie?
It is not a virus, a Trojan horse, a worm, spam, spyware, or a pop-up ad.
What information does a cookie store?
Cookies typically do not store sensitive information about you, such as credit card details or banking information, photos, your ID, or personal data. The data they store is of a technical nature, including personal preferences, content customization, etc.
The web server does not associate you as a person but rather with your web browser. In fact, if you usually browse with Internet Explorer and try to browse the same site 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 individual.
What types of cookies exist?
- Technical cookies: These are the most basic and allow, among other things, to determine when a human or an automated application is browsing, when an anonymous user and a registered user are navigating, and perform basic tasks for the functioning of any dynamic website.
- Analytics cookies: They collect information about the type of browsing you are doing, the sections you use the most, products consulted, time of use, language, etc.
- Advertising cookies: They display ads 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 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?
To understand the impact of disabling cookies, here are a few examples:
