Use of cookies

Cookies are short pieces of text (letters and/or numbers) that allow the web server to store information on the client (the browser) to be reused during the same visit to the site (session cookies) or later, even days later (persistent cookies).

Cookies are stored, based on user preferences, by the individual browser on the specific device used (computer, tablet, smartphone).

Similar technologies, such as web beacons, transparent GIFs, and all forms of local storage introduced with HTML5, can be used to collect information about user behavior and the use of services.

In the following document, we will refer to cookies and all similar technologies simply using the term “cookies.”

Types of Cookies

Based on the characteristics and use of cookies, we can distinguish different categories:

Strictly Necessary Cookies. These are essential cookies for the proper functioning of the sites and are used to manage login and access to the site’s reserved functions. The duration of these cookies is generally limited to the work session (they are deleted when the browser is closed), but in some cases and without any notice, longer-lasting cookies (with a 30-day expiration) can also be used to recognize the visitor’s computer for that period, through an alphanumeric code generated at the first access session, in order to present the user with the result of the test performed. Disabling them compromises the use of services accessible through login. The public part of the sites remains normally usable.

Analysis and Performance Cookies. These cookies are used to collect and analyze traffic and site usage anonymously. These cookies, without identifying the user, allow, for example, the detection of whether the same user reconnects at different times. They also allow monitoring the system and improving its performance and usability. Disabling such cookies can be done without any loss of functionality.

Profiling Cookies. These are permanent cookies used to identify user preferences (anonymously and non-anonymously) and improve their browsing experience.

Third-Party Cookies

While browsing the web, you may receive cookies from both the visited site (“first-party”) and sites operated by other organizations (“third parties”). A notable example is the presence of “social plugins” for Facebook, Twitter, LinkedIn, etc. These are parts of the visited page generated directly by these sites and integrated into the hosting site’s page. The most common use of social plugins is for sharing content on social networks.

The presence of these social plugins involves the transmission of cookies to and from all sites operated by third parties. The management of information collected by “third parties” is governed by their respective policies, which you are encouraged to refer to. For greater transparency and convenience, the web addresses of the different policies and cookie management methods are provided below.





Google Analytics

The sites also include certain components transmitted by Google Analytics, a web traffic analysis service provided by Google, Inc. (“Google”). In this case too, these are third-party cookies collected and managed anonymously to monitor and improve the performance of the hosting site (performance cookies).

Google Analytics uses “cookies” to collect and analyze information about the anonymous usage behavior of websites (including the user’s IP address). This information is collected by Google Analytics, which processes it to create reports for operators regarding activities on the websites. This site does not use (and does not allow third parties to use) Google’s analysis tool to monitor or collect personally identifiable information. Google does not associate the IP address with any other data held by Google nor does it attempt to link an IP address with a user’s identity. Google may also disclose this information to third parties where required by law or where such third parties process the information on Google’s behalf.

Users can selectively disable Google Analytics by installing the opt-out component provided by Google on their browser. To disable Google Analytics, please refer to the link below:

Cookie Duration

Some cookies (session cookies) remain active only until the browser is closed or the logout command is executed. Other cookies “survive” the closure of the browser and are available in subsequent user visits.

These cookies are called persistent, and their duration is set by the server at the time of their creation. In some cases, an expiration date is set, while in other cases, the duration is unlimited.

However, while browsing the pages of websites, you may interact with sites operated by third parties that can create or modify permanent and profiling cookies.

Cookie List

Cookie Domain Type Expiration Description
PHPSESSID Functional 1 year Cookie generated by PHP-based applications. It is a general-purpose identifier used to maintain user session variables. It is usually a randomly generated number, and its usage can be site-specific, but a common example is to maintain a user’s login status across pages.
_gid Performance 1 day ID used to identify users for 24 hours after their last activity.
_gat_gtag_UA_183969604_1 Performance 1 day Used to monitor the number of requests to the Google Analytics server when using Google Tag Manager.
_ga_601CEBRZGL Performance 1 year This cookie is used by Google Analytics to maintain session state.
_ga_8EZLJJXCWT Performance 1 year This cookie is used by Google Analytics to maintain session state.
_ga Performance 1 year The name of this cookie is associated with Google Universal Analytics, a major update to the commonly known Google Analytics service. The new service reduces dependence on cookies in general and only sets _ga and another one—_gat, although Google claims data can be collected even without setting cookies. This cookie is used to distinguish unique users by assigning them a randomly generated number as a client identifier. It is included in every page request on a site and used to calculate visitor, session, and campaign data for site analytics reports.
_gcl_au Marketing Persistent This cookie is used by Google Adsense to store and track conversions.
_fbp Marketing 3 months This cookie is used by Facebook to store and track visits to different websites.
YSC Marketing Session This cookie is set by YouTube to track views of embedded videos.
