Kindle confidentiality and security questions
I have a couple of questions regarding the confidentiality of documents (PDFs) loaded onto a Kindle:
1.
Is it possible to securely load a confidential document onto a Kindle? Can I simply load a document from my computer, in other words, via USB, to the Kindle, without that document ever traveling elsewhere? Will any PDF I load onto my Kindle (say, through Calibre) also be ported somehow to Amazon.com?
2.
I have not yet purchased the Kindle but I’m going to soon. I’m mostly interested in using it as a personal PDF reader. If I decided to return it, is there a guaranteed, safe and secure way to erase PDFs that you’ve loaded onto the Kindle? Can one restore a Kindle to its original state, or will even a post-restore Kindle still contain your document somewhere, just as erased Windows files will remain on your HD (unless they are DBANd and the like) and are often retrievable? I’m curious about text-only PDFs if that matters.
Thank you.
