What are cookies?
Cookies are small files or devices that are downloaded and stored on the terminal or device that you use to access the internet (such as computers, mobile phones, tablets and any other connected devices…) that allow websites to remember user information as you browse (for example, to store and retrieve information about your browsing habits or your computer, to see which web pages you visit, the connection time, etc., to analyse the operation of a web page, if there are any technical problems, etc.).
Generally speaking, there are several types of cookies:
Depending on the entity that manages the computer or domain from which cookies are sent and handles the data obtained, we can distinguish:
Own cookies: are sent to the user's computer or terminal from a computer or domain managed by the web page editor, in this case the ONCE, from which the service requested by the user is provided.
Third-party cookies: are sent to the user's terminal computer from a computer or domain that is not managed by the web page editor, but by another entity that handles the data obtained through cookies. If cookies are installed from a computer or domain managed by the ONCE, but the information collected through these cookies is managed by a third party, they cannot be considered ONCE's own cookies. In this regard, ONCE may engage the services of analysis and measurement companies that measure and analyse users’ browsing habits on the platform and, in this regard, act on their behalf by analysing the data obtained with the use of these third parties’ cookies, all this for the sole purpose of improving the service provided by the ONCE.
Depending on the purpose for which the data obtained through cookies are processed, we can differentiate between:
Technical cookies (required): enable the user to navigate through the platform and use the different options or services that exist on the platform, such as controlling traffic and data communication, identifying the session, accessing restricted information, remember the items that make up a request, make a request to register or participate in an event, use security features while browsing, store content for streaming video or audio, or share content via social media.
Functional or personalisation cookies (Preferences): allow the user to access the service with some general predefined characteristics based on a number of criteria on the user terminal, such as the language, the type of browser with which the user accesses the service, or the browser from which they access the service, among others.
Analytics cookies (Statistics): enable the person responsible for these cookies to track and analyse the behaviour of users of the websites to which they are linked. The information collected by this type of cookie is used to measure activity on the platform and to create browsing profiles for users of such sites, applications and platforms, to make improvements based on the analysis of usage data made by service users.
Advertising cookies (Marketing): enable the most efficient management of advertising spaces that, if any, the publisher has included on a website, the application or platform from which the requested service is delivered based on criteria such as the content edited or how often ads are displayed.
Behavioural advertising cookies (Marketing): enable the efficient management of any advertising spaces the publisher has included in a web page, application or platform from which it provides the requested service. These cookies store information about the behaviour about users obtained through continuous observation of their browsing habits, which makes it possible to develop a specific profile to show advertising accordingly.
Depending on the length of time they remain activate on the equipment or terminal (expiration), we can differentiate between:
Session cookies: cookies designed to collect and store data while you access the platform. Session cookies allow a website to recognise the user.
Persistent cookies: cookies in which data are still stored on the terminal and may be accessed and processed for a period defined by the cookie owner, which can range from a few minutes to several years.
