Hallo!
Since some weeks I´m using my new german Kindle Touch and I´m very happy with it. After my online registration on Amazon I deactivated the WiFi and only use calibre to put ebooks in the Kindle Touch, because I heard, Amazon syncs all books to its cloud. I think Amazon doesn´t have to know all about my books, because I found some interessting one in this forum and copied them to my KT.
Is it possible to use WiFi without the automatic sync to Amazon?
Or do you think I´m a bit paranoid and should use WiFi, don´t thinking about the sync to Amazon?

and best regards,
Dirk
