What is a cookie?
A cookie is a file or device that is downloaded to the terminal equipment of an Internet user when he or she browses it in order to store and retrieve data found on this equipment and that reflect the user’s activities during their navigation time.
With it, Internet service providers can fulfill some functions such as:
- Facilitate user navigation through the websites he or she visits;
- Provide information on the browsing habits of website users, to develop new products or services;
- Provide information on the browsing habits of users of websites, to direct behavioural advertising.
Cookies, depending on the time they remain activated, can be:
- Session cookies, which collect and store data while the user accesses a web page and that will be deleted once the user leaves the web page that generated them
- Persistent, which remain on the computer until a certain date and can be accessed and processed during a period defined by the person responsible for the cookie, which can range from a few minutes to several years.
Depending on who sets them, cookies can be:
- proprietary, managed by the domain to which the user accesses and from which a specific service is requested
- third-party cookies, which are enabled by other service providers with whom the owner of the site that the user visits has contracted the provision of certain services
Cookies, depending on their purpose, can be:
- Technical: those that allow the user to navigate through a web page, platform or application and the use of the different options or services that exist in it, including those that the editor uses to allow the management and operation of the web page and enable its features and services.
- Analytical: those that, when processed by the owner of the site or by third parties, allow quantification of the number of users and thus carry out the measurement and statistical analysis of the use that users make of the service offered, in order to improve the product offer and services offered.
- Advertising cookies: these enable more efficient management of the advertising spaces which the publisher may have included on the website, application or platform where the requested service is provided, based on criteria such as the published content or the frequency with which adverts are shown.
- Behavioural advertising cookies: these enable the most efficient management possible of advertising spaces which, if applicable, the publisher has included in a website, app or platform from which the requested service is rendered. These cookies store information about the user’s activity, obtained by continuously monitoring their browsing habits, which makes it possible to create user-specific profiles and display advertisements that match the user’s interests. Furthermore, if a website is visited or an email opened with an advert or promotional material regarding our products or services, a cookie may be installed on the browser to help us to display adverts related to the searches made, and to monitor our adverts in terms of, for example, the number of times they are viewed, where they appear, what time they are viewed, etc.
Technical cookies can be implanted in the user’s terminal without the need for any consent. In contrast, analytical, advertising and tracking cookies need the user’s consent.
