So if your phone doesn’t move from a single location between the hours of 10 p.m. and 6 a.m. for say a week or so, Facebook can quickly deduce the location of your home. Facebook will be able to pinpoint on a map where your home is, whether you share your personal address with the site or not. It can start to build a bigger and better profile of you on its servers. It can start to correlate all of your relationships, all of the places you shop, all of the restaurants you dine in and other such data. The data from accelerometer inside your phone could tell it if you are walking, running or driving. As Zuckerberg said — unlike the iPhone and iOS, Android allows Facebook to do whatever it wants on the platform, and that means accessing the hardware as well.
This future is going to happen – and it is too late to debate. However, the problem is that Facebook is going to use all this data — not to improve our lives — but to target better marketing and advertising messages at us. Zuckerberg made no bones about the fact that Facebook will be pushing ads on Home.

Facebook also keeps close track of where millions more non-members of the social network go on the Web, after they visit a Facebook web page for any reason.
