Cookie policy


Cookies are small text files that are placed on your computer by websites that you visit. They are widely used in order to make websites work, or work more efficiently, as well as to provide information to the owners of the site.

Websites mainly use cookies to:

  • identify users;
  • remember users' custom preferences;
  • help users complete tasks without having to re‑enter information when browsing from one page to another or when visiting the site later.

Cookies can also be used for online behavioral target advertising and to show adverts relevant to something that the user searched for in the past.

The web server supplying the webpage can store a cookie on the user's computer or mobile device. An external web server that manages files included or referenced in the webpage is also able to store cookies. All these cookies are called http header cookies. Another way of storing cookies is through JavaScript code contained or referenced in that page.

Each time the user requests a new page, the web server can receive the values of the cookies it previously set and return the page with content relating to these values. Similarly, JavaScript code is able to read a cookie belonging to its domain and perform an action accordingly.

A cookie can be classified by its lifespan:

  • session cookie which is erased when the user closes the browser;
  • persistent cookie which remains on the user's computer/device for a pre-defined period of time

and the domain to which it belongs:

  • first-party cookies which are set by the web server of the visited page and share the same domain;
  • third-party cookies stored by a different domain to the visited page's domain. This can happen when the webpage references a file, such as JavaScript, located outside its domain.

Some types of cookies do not require consent of the website visitors:

  • user‑input cookies (session-id) such as first‑party cookies to keep track of the user's input when filling online forms, shopping carts, etc., for the duration of a session or persistent cookies limited to a few hours in some cases;
  • authentication cookies, to identify the user once he has logged in, for the duration of a session;
  • user‑centric security cookies, used to detect authentication abuses, for a limited persistent duration;
  • multimedia content player cookies, used to store technical data to play back video or audio content, for the duration of a session;
  • load‑balancing cookies, for the duration of session;
  • user‑interface customisation cookies such as language or font preferences, for the duration of a session (or slightly longer);
  • third‑party social plug‑in content‑sharing cookies, for logged‑in members of a social network.

The information below explains the cookies we use and why.

Google Analytics cookies are added to our website pages via a piece of JavaScript code.

__utma Cookie

A persistent cookie - remains on a computer for 2 years, unless it expires or the cookie cache is cleared. It tracks visitors. Metrics associated with the Google __utma cookie include: first visit (unique visit), last visit (returning visit).

__utmb Cookie & __utmc Cookie

These cookies work in tandem to calculate visit length. Google utmb cookie demarks the exact arrival time, then Google utmc registers the precise exit time of the user.

Because utmb counts entrance visits, it is a session cookie, and expires at the end of the session, e.g. when the user leaves the page. A timestamp of 30 minutes must pass before Google cookie utmc expires. Given__utmc cannot tell if a browser or website session ends. Therefore, if no new page view is recorded in 30 minutes the cookie is expired.

__utmz Cookie
