What are cookies?
Cookies are tiny information files stored by the websites you visit on the browser of the device with which you surf the internet (such as your computer or mobile phone). These files help the website memorize information about your visit and streamline your next visit: storing your actions and preferences for a certain period of time, storing or recognizing your username, the language in which you wish to browse the site, and other settings.
Cookies can be classified according to several criteria.
Based on their purpose, cookies can be:
- (a) Strictly necessary cookies - These are cookies that are necessary to ensure the functioning of the website and/or the availability of specific features requested by the user, as well as to store their browsing preferences, whenever they so request and use the same device.
- (b) Personalisation cookies - These are accessory cookies (not necessary for the functioning of the website, although they can improve its performance) and their purpose is to customize the user's browsing experience.
- (c) Analytics cookies - These are accessory cookies which collect statistical information in order to help website owners analyze its usage and understand visitor engagement with the website. These cookies may also be used in conjunction with some advertising cookies to quantify interactions with the advertisements presented on the website.
- (d) Advertising cookies - These are accessory cookies that aim to make advertising more attractive to both users and advertisers by offering advertisements that are relevant to the user, in order to improve reporting on campaign performance and to avoid placing advertisements which the user has already seen or flagged as irrelevant.
Considering their life cycle, cookies can be classified as follows:
- (e) Session cookies - These are provisional cookies that are deleted from the cookies archive when or shortly after the user closes the browser or application that has been used to browse the Digital Channels. These cookies make it possible, for instance, to analyze traffic patterns on the web, allowing us to identify issues, improve security, and provide a better browsing experience.
- (f) Persistent cookies - Unlike session cookies, these cookies are not deleted when the user closes the browser or application and are stored on the user's devices. They are used whenever the user visits the website again, allowing us, for instance, to customize the browsing experience according to the user's interests and provide a more customized service.
Considering the party that places them, cookies can be classified as follows:
- (a) First-party cookies - These cookies are sent to the user's device from equipment or domains managed by EDP which provide the service requested by the user.
- (b) Third-party cookies - These cookies are sent to the user's device from a third-party device or domain over which EDP has no control. In such cases, the third party may process the data collected by cookies and EDP may not have the ability to configure the cookies’ operation.
