What is a cookie?
A cookie is a harmless text file which is stored in your browser when you visit almost any web page. The usefulness of cookie is that the web is able to remember your visit when you surf this page again. Although many people do not know, the cookies have been in use for 20 years, when the first browsers for the World Wide Web appeared.
What is NOT a cookie?
It is not a virus or a Trojan, not a worm, or spam, or spyware, nor does it open pop-up windows.
What information does a cookie stores?
Cookies do not usually store sensitive information about you, such as credit card or bank account information, photographs, your ID or personal information, etc. The data stored are technical, personal preferences, content personalization, etc.
The web server does not associate you as a person but to your web browser. In fact, if you regularly browse with Internet Explorer and try to browse the same web with Firefox or Chrome you will see that the web does not realise that you are the same person because you are actually associating the browser, not the person.
What kind of cookies are there?
- Technical Cookies: These are the most basic and allow, among other things, knowing whether is a human who is browsing or an automated application, when an anonymous user and a registered user navigates, basic tasks for running any dynamic web.
- Analysis Cookies: They collect information on the type of navigation which is being performed, the sections most used, the consulted products, the time period of use, the language, etc.
- Advertising Cookies: They display advertisements based on your navigation, country of origin, language, etc.
What are the own cookies and third-party cookies?
The “own cookies” are those generated by the page you are visiting and the “third-party cookies” are generated by internal or external providers such as Facebook, Twitter, Google, etc.
