A cookie is a small text file that some pages deposit in the browser and that serve to store information regarding the use of the web. These cookies allow, for example, to save web preferences (in the case of webs that allow personalization, such as changing the color of the text or the background), or data such as the username and access password, so that it is not necessary to enter the data on each new visit.
Cookies only contain information. Therefore, they are not dangerous. They are not viruses, spyware, malware, or anything like it. So why does the EU consider that they should be controlled? Well, these cookies can also store browsing habits, which can be used by third parties to show us, for example, targeted advertising. Suppose we regularly consult travel pages. This information may be useful to any advertising engine to show us advertisements for promotions, discounts etc... from travel agencies.
