We may add third-party computer applications to our Website to enable us to share content from our Website with others or to inform such others of your visits or your opinions on our Website content. This is specifically the case for the “Share” and “Like” buttons used by social media such as Facebook, Twitter, etc. The social media platform concerned may identify you using this button even if you have not used it when visiting our Website. This type of application button can enable social media to track your browsing on our Website due simply to the fact that your social media account was activated in your web browser (i.e. a session has been opened) while you have been browsing on our Website. We have no control over the processes used by social media to collect information on your browsing on our Website and associated with the personal data they possess. We recommend that you take note of the terms and conditions of use of your data by such social media in order to ascertain the purposes of this use, notably for advertising, and the browsing data they may collect using such application buttons. You should ensure that the terms and conditions for use of such social media enable you to control and restrict their use of your data, notably by configuring your user accounts with those media.

4.  Sharing your terminal with other users

If your terminal is used by more than one person and where the same terminal has more than one web browser installed, we cannot guarantee with any certainty that the services and advertising directed at your terminal match correctly your own use of that terminal and not that of another user. Sharing your terminal with others and the configuration of your web browser with regard to cookies are matters of personal choice for which you bear responsibility
