In accordance with article 13 of D.Lgs. n. 196/03 "Personal data protection Code" (below "Code") this legislation explains what cookies are and describes the various types of cookies on the internet site (below the "site"). Cookies are small text files that the sites visited by the user send and register on his computer or mobile system, and send again to the same website when it is visited again.

Thanks to cookies, the site reminds the user of his preferences and actions (like for example login data, selected language, font size, other display settings, and so on) so that they cannot be specified once more when the user goes back to visit the site or surfs from one page to another. So, cookies are used to perform computer authentication, monitor the sessions and memorize information concerning the activities of the users who log on to a website and can also include a unique tracking number (code) which allows to keep a track of the user's web surfing on the same website for statistical and advertising purposes. While surfing on a website, the user can also receive on his computer or mobile system cookies of websites or web servers that are different from the ones he's visiting (so-called "third party cookies"). Some operations can be accomplished without the use of cookies, that in some cases are technically necessary for the website operation.

There are different types of cookies, according to their characteristics and functions, and they can remain in the user's computer or mobile system for different lengths of time: so-called session cookies, which are automatically canceled when the browser is closed; so-called persistent cookies, which persist on the user's device up to a predetermined expiration.

According to the regulation in force in Italy, the user's express consent is not always required to use cookies. In particular, the so-called "technical" cookies don't require any consent, namely those used only for the purpose of carrying out transmission of a communication on an electronic communication network, or in the strictly necessary measure to distribute a service explicitly required by the user. In other words, cookies that are essential for website operation and necessary to perform activities required by the user.

Among technical cookies, which do not require consent for their use, the Italian authority for personal data protection (see above Prov. Gen. "Identification of simplified modalities for agreement information and acquisition for the use of cookies - 8 May 2014") also includes:

  • "analytics cookies" where directly used by the supervisor of the website to gather information, in aggregate form, about the number of users and how often they visit the same website;
  • "session or surfing cookies" (to authenticate oneself, to make a purchase and so on);
  • "functionality cookies" which allow the user to surf depending on a series of selected criteria (for example: the language, the products selected for the purchase) with purpose to improve the service given to him.

Instead for profiling cookies, namely those intended to create profiles concerning the user and used in order to send advertising messages in line with the preferences expressed by the same in the web surfing sphere, a user's prior consent is required.

In particular, the site uses:

  • Technical cookies, that is surfing or session cookies strictly necessary for the website operation or to allow the user to enjoy the contents and services he requires.
  • Analytics cookies, which help to understand how the website is used by consumers. These cookies do not gather information about the user's identity, neither any personal data. Information is treated in an aggregate and nameless form.
