Seems that a good measure for them not gaining much data about you is to keep logging in an incognito window and not liking much. All the Interests I see are from where I login (mobile phone models, browsers, OS), one Android wrapper app, apps I linked with FB and 1 Facebook page I liked (football club). Good news, less data FB has on me, more it makes me happy.
