Congressional Hearing on Google reveals smart phones report your position, every minute

Scary,  Testimony in front of Congress this morning claims that Android cell phones report their ( and their owners) position about once a minute.  I only carry a cheap dumb phone.  I wonder what it is reporting, and to whom it reports to.    The idea that the government, the cops, NSA, FBI and who knows who else can know where I am, minute by minute, is scary.  I certainly am not gonna update to a smart phone.
