Kindle

 Kindle  is Amazon's book silo service and hardware e-reader devices for viewing those books. They utilize a number of proprietary file types including .mobi, .azw, .tpz, and others that often include DRM protection and prevent books from being transferred easily from one device to another or from being converted to other file types.

Data Export
Book files can often be exported directly from most devices by connecting them directly to a computer.

Highlights and Annotations
These are typically kept in a file named  which is a simple text file with the highlights and annotations along with date and timestamps.

Highlights and annotations are also synced to Amazon's site at https://read.amazon.com/notebook and if one has a linked Goodreads account, they will be mirrored at https://www.goodreads.com/notes/.

Several services offer alternate means for extracting some Kindle data:
 * Clippings.io offers a paid service (as a Chrome extension) that exports Kindle annotations in a variety of formats. There is a free version that allows uploading of myclippings.txt to extract clippings. It also supports export to Evernote.


 * Calibre offers an import data tool


 * diigo is a bookmarking service that offers methods to export Kindle annotation data Introduce a new way to retain knowledge from Kindle books by Joel Liu


 * Readwise Will allow you to sync your Kindle, iBooks, and Instapaper highlights and review them.
 * Bookcision provides a bookmarklet that allows export of annotations by book from Kindle in plain text, XML, and JSON formats.


 * Klib.me

Reading Data
By putting your Kindle into FreeTime mode (usually used by Parents for their kids), your Kindle will track your pages read, minutes read, books finished, words looked up, and "achievements". They also save a file on your Kindle that allows you to extract the data. It is stored in a SQLite file on your device under system > freetime > freetime.db.
