After running #peerblock in my laptop to block unwanted connections. Seems like my windows always share data and mostly to #haliburton when I checked they no #tech firm. So yeah there is that. Its a while back though. I know that there will be more like them nowadays.
@LogicalDash apparently #MoBlock has been deprecated in favour of #PeerGuardian:

A quick web search turns up #PeerBlock as a possible Android equivalent.
