Our web pages may contain plug-ins of the most popular social networks (a.e. Facebook, Twitter, Linkedin) managed by the third parties involved. Such plug-ins could for example correspond to the "Like" buttons on Facebook or "Retweet" on Twitter. If you access one of our web pages, equipped with a similar plug-in, the internet browser connects directly to the third-party servers and the plug-in is displayed on the screen thanks to the connection with the browser. The plug-in may communicate to third-party servers which pages the user has visited. If a social network user visits our web pages while connected to their account, this information could be associated with the account. Even if the plug-in functions are used (for example, by clicking on the "Like" button), the information will be associated with the account.
