So I downloaded my facebook data a few days ago and there were no phone nrs in there, no call history, actually much less of everything than I thought they'd have. Are they lying to me or does this depend on other factors?
The download-your-data feature for a time showed the truth, in 2013: http://www.zdnet.com/article/firm-facebooks-shadow-profiles-...
So we may presume FB, especially in the US with little-to-no privacy laws against corporations, won't tell you what the really know.
