Types of cookies according to the entity that manages them:

Depending on who is the entity that manages the equipment or domain from where the cookies are sent and treat the data obtained, we can distinguish:

Own Cookies: These are 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: These are 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 the cookies.

In the event that the cookies are installed from a computer or domain managed by the editor itself, but the information collected through these is managed by a third party, they cannot be considered as own cookies.
