WHAT ARE COOKIES?
"Cookie" (or connection witness) is a small piece of data (text file) that a website - when visited by a user - asks your browser to store on your device in order to remember information about you, such as your language preference or login information.
In some cases, cookies are necessary to facilitate navigation and enable us to save and recover information about a user's browsing habits or equipment, among others, and depending on the information they contain and the way you use your equipment, they can be used to recognise you.
On our website, cookies allow us to improve the performance and your browsing experience by, on the one hand, increasing the speed and efficiency of response and, on the other hand, eliminating the need to repeatedly enter the same information.
HOW CAN COOKIES BE CLASSIFIED ACCORDING TO WHO ADMINISTERS THEM?
When cookies are set by us, they are called first-party cookies.
But when they are set by websites that do not belong to us, they are called third-party cookies. A website may use external services, which also set their own cookies.
HOW CAN COOKIES BE CLASSIFIED ACCORDING TO THE PERIOD THEY REMAIN ACTIVE ON THE USER'S SYSTEM?
Session cookies, collect and store data when the user accesses a web page and are automatically deleted when the user leaves their browser.
Persistent cookies, on the other hand, store the data in the terminal in such a way that it can be accessed and processed for a period defined by the person responsible for the cookie - from a few minutes to several years.
