CWatkinsNash, you
might find some useful information about what data is being sent to Amazon, or how to find it, in this thread:
https://www.mobileread.com/forums/sho...t=51371&page=2
I don't know how applicable it is, or, more important, under what settings the transmissions are sent.
Same goes for the article's warnings...
I mean, for the K3 at least, you can select to have Amazon keep track your notes and marks, and/or track your last page read for the purpose of synchronizing.
Since those are optional, the only thing that would be questionable to me is if they were still being tracked when I had those options turned off. I asked about it in that thread, but
Longitude and latitude info are part of running 3G, although I'm not sure why that location data is regularly logged and sent to Amazon by default instead of only as needed for troubleshooting connection issues.
I guess next time I go rob a bank, I'll leave my Kindle at home.
