title_body: Can you use a Kindle without an Amazon account?
upvoted_answer: I just got a new paperwhite, and am reading my own books on it without registering. It nags you to register, but if you open Calibre, and then connect via USB, you can put books on, and it all works just as normal. The only thing you can't do if you don't register is to "buy" Amazon's drm books, or access the ones you've already "bought." 
  
  Although it is possible you may be able to transfer said books through your kindle desktop app, I haven't tried,don't really care.
