What are cookies and what are they used for?
A cookie is a file that is downloaded to the computer, tablet, smartphone or any other device on accessing certain websites. Cookies allow a website to store and retrieve information about a user or device's browsing habits and depending on the information it contains and how the device is used, they can be used to recognise a user. Under no circumstance can cookies damage your device. In fact, enabling cookies helps us to identify and resolve possible errors.
Below is a list of cookies arranged into a series of categories. However, bear in mind that a cookie could be included in more than one category.
Cookies according to the entity that manages them:
Depending on the entity that manages the server or domain from which the cookies are sent and which processes the data they contain, cookies can be classified into:
- First-party cookies: These cookies are sent to the user's device from a server or domain managed by the publisher and which provides the service requested by the user.
- Third-party cookies: These cookies are sent to the user's device from a server or domain that is not managed by the publisher but by another entity that processes the data collected through cookies.
If cookies are installed from a server or domain managed by the publisher but the information collected though them is managed by a third-party, they are not classed as first-party cookies.
Types of cookies according to how long they remain activated:
Depending on how long they remain activated on the device, cookies can be divided into:
- Session cookies: These cookies are designed to gather and store data when the user accesses a website. They are usually used to store data that is only needed to provide the service requested by the user on one occasion (e.g. a list of products purchased).
- Persistent cookies: These cookies are stored on the device and can be accessed and managed over the period of time defined by the entity in charge of the cookie, which can range from minutes to several years.
Cookies according to their purpose:
