Cookies policy


A cookie is a text file that the web server to which the user accesses stores on their device to save and consult during future visits useful information about browsing (session started, language chosen, etc.) in order to offer a comfortable browsing experience tailored to the user's preferences.

Cookies are not considered risk files because they cannot identify individuals by themselves, do not refer to any personal data and cannot be executed as automated computer code, therefore, they cannot contain any virus or malicious software.

Cookies are divided into two categories according to their purpose:

The duration of this cookie can vary between 1 day and up to 1 week.
