When you actively use a Facebook-function, i.e. by clicking on the like-button, it is possible that Facebook processes further data. Facebook can for instance set a cookie that allows Facebook to see whether you have already clicked another like-button on another website that also provides a Facebook-button. If you are also logged into Facebook as a Facebook user, Facebook can moreover tell which pages of you have visited. If you click a Facbook-button on and log into Facebook afterwards (or if you are already logged in), the information you “liked” or “shared” may be posted on your profile or your timeline in abbreviated form. Facebook may thus collect and store further user data. This may lead to Facebook user profiles that exceed that which you have shared on Facebook itself.

At no point in time does Publixphere learn which Facebook buttons you have used.
