Howdy. I'm disturbed by the fact that cell phones are constantly pinging the cell tower, and this information is stored by the phone company indefinitely. I don't use my phone for much (I'm a bit of a Luddite). I'm already in the habit of ignoring texts until later in the day. I do get the occasional phone call, but most of those can also be ignored until later in the day. If I keep my phone in airplane mode whenever I'm out of the house, does that prevent the phone company from tracking my whereabouts? I can always take it out of airplane mode on the rare occasions that I actually need to make a call or check texts. Yes, the phone company then gets a bead on my position, but they've still missed the bulk of my movements. I know that cell phones supplement their geolocating by looking for nearby wifi access points. I think this has to do with the 911 system, since cell-tower data is imprecise. Does the cell phone keep a log of my travels via its wifi sniffing, which it then uploads the next chance it gets? Or is there yet another way that these things track us that I'm missing?
