What are cookies?
Cookies are files that can be downloaded to your computer through web pages. They are tools that play an essential role in the provision of numerous services of the information society. Among others, they allow a web page to store and retrieve information about the browsing habits of a user or their equipment and, depending on the information obtained, they can be used to recognize the user and improve the service offered.
What types of cookies are there?
Depending on who is the entity that manages the domain from which cookies are sent and treats the data obtained, two types can be distinguished:
- Own cookies: those that are sent to the user’s terminal equipment from a computer or domain managed by the publisher itself and from which the service requested by the user is provided.
- Third-party cookies: those that are sent to the user’s terminal equipment from a computer or domain that is not managed by the publisher, but by another entity that processes the data obtained through cookies.
In the event that cookies are installed from a computer or domain managed by the publisher itself but the information collected through them is managed by a third party, they cannot be considered as their own cookies.
There is also a second classification according to the period of time that they remain stored in the client’s browser, which may be:
- Session cookies: designed to collect and store data while the user accesses a web page. They are usually used to store information that only interests to keep for the provision of the service requested by the user on a single occasion (e.g. a list of purchased products).
- Persistent cookies: the data is still stored in the terminal and can be accessed and processed for a period defined by the person responsible for the cookie, which can last from a few minutes to several years.
