When you visit Our websites, We will indicate that We are using cookies for the different purposes explained above and We will ask for your consent before putting advertising and analytical cookies on your computer’s hardware.

Some cookies, which We consider essential for the running of our websites and the so-called system cookies, are automatically put on your computer’s hardware and do not require your consent.

4. When are cookies deleted from your computer’s hardware?

There are two kinds of cookies:

  • Session cookies which are deleted once you close your browser;

  • ClickDimension.

The data that We share with these service providers are limited to the data as mentioned in Section 2.3. and are only used for managing our advertisements, for analysing how visitors use Our website and to propose you some services (such as the possibility to share information put on Our websites on your social media account).

6. Do We transfer data outside the European Union?

To the extent that We use the services of third parties, which are situated outside the European Union (LinkedIn, Google, DoubleClick) in order to analyse your navigation on Our websites, there may be transfers of your personal data outside this geographic area, especially in the United State of America (USA).

However, We have made sure the transfer is properly secured, as all these undertakings are part of the Privacy Shield and/or bound by standard contractual clauses as adopted by the European Commission.

7. How can you manage cookies put on your computer’s hardware?

Regardless of the kind of cookies put on your computer’s hardware, including functional and system cookies, you have the possibility to manage them at any time by using the following procedure.

However, We would like to draw your attention to the fact that by changing the settings of these cookies (for example: by refusing cookies), your navigation on Our websites but also on other websites you will visit may be affected.

There are several ways of managing cookies, which are explained further below. In particular, you can do so either by:

  • Managing them in your browser;
  • Managing analytical cookies processed by Google Analytics.

7.1. How to manage cookies through your browser?

Through the browser that you use, you will be able to:

  • See what kind of cookies you have on your computer’s hardware and delete them;
  • Block third party cookies;
  • Block cookies from particular websites;
  • Block all cookies from being set;
  • Delete all cookies when you close your browser.

In order to understand how to do so in practice, since each browser may have a different procedure, We invite you to visit the dedicated pages on the browsers’ site (Internet Explorer, Mozilla Firefox, Chrome, Safari, etc.).

Moreover, if you want to know how to manage them with other browsers than those listed above, We invite you to do so by visiting http://www.aboutcookies.org.

7.2. Managing analytical cookies

It is also possible for you to manage analytical cookies proposed by Google analytics by downloading the Opt-Out Browser Add-on. This Add-on will prevent cookies from Google Analytics to be put on your computer’s hardware regardless of the visited website.

However, this solution is solely applicable to cookies used by Google Analytics.
