Depending on who is the entity that manages the domain from which cookies are sent and treat the data obtained can distinguish two types:

• Own Cookies: Those that are sent to the user’s terminal equipment from a computer or domain managed by the editor 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 editor, 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 editor but the information collected through these is managed by a third party, they cannot be considered as own cookies.

There is also a second classification according to the length of time they remain stored in the client’s browser, being able to be:

• Session Cookies: Designed to collect and store data while the user accesses a web page. They are usually used to store information that is only interesting to keep for the provision of the service requested by the user on a single occasion (e.g. a list of products purchased).
• Persistent Cookies: The data remains stored in the terminal and can be accessed and processed for a period defined by the party responsible for the cookie, which can range from a few minutes to several years.
