Dolphin, Boat, Ninesky, Maxthon...most browsers out there spy on you
in one way or another and that linked thread talks about many of them. Not only is this an invasion of privacy, it wastes your battery power, bandwidth, and CPU cycles. In response to this garbage I created a free browser that does not spy in any way. Fast and full-featured: Naked Browser in the Google Play Store
. This is a not for profit app.
