• Proprietary cookies: Sent to the user’s device from equipment or a domain managed by the publisher of the website from which the service requested by the user is provided.
• Third-party cookies: Sent to the user’s device from equipment or a domain that is not managed by the website published, but rather by another entity that processes the data obtained through the cookies. In cases where the cookies are installed from a computer or domain managed by the publisher, but the information collected through them is managed by a third party, they cannot be considered proprietary cookies. There is also another classification based on the period of time during which cookies remain stored in the client’s browser:
• Session cookies: Designed to collect and store data while the user browses through a website. These are normally used to store information which is only kept for the provision of the service requested by the user on a single occasion (e.g. a list of bought products).
• Persistent cookies: The data is still stored in the computer terminal and can be accessed and processed for a time period defined by the cookie owner, which can range from a few minutes to several years.
2 Finally, there is another classification involving six types of cookies according to the purpose of the processing of the data obtained:
• Technical cookies: Cookies that allow you to browse the website, platform or application and use the different options or services that it provides, such as controlling data traffic and communication, session identification, accessing to restricted access sections, saving elements that make up an order, undertaking the order process, processing sign up requests or event participation, using security elements during browsing, storing security contents to broadcast videos or audio, or sharing content via social networks.
• Personalisation cookies: Let you access the service with some general predefined features in terms of a series of criteria on your terminal, such as language, browser used to access the service, regional settings for the location you are accessing the service from, etc.
• Analytical cookies: Allow the person responsible for them to monitor and analyse the behaviour of the users of the websites to which they are linked. The information collected through this type of cookie is used to measure the activity of the websites, application or platform and to create browsing profiles of the users of said sites, applications and platforms, with the object of making improvements based on analysis of the usage data of the users of the service.
• Advertising cookies: Allow the most efficient management possible of advertising spaces, etc.
• Behavioural advertising cookies: These store your behavioural data, obtained by continually observing your browsing habits, to enable the development of a specific profile so that advertising can be displayed accordingly.
