Kindle books are not currently stored in the cloud because they do not use a browser. The content is downloaded through a wireless connection and stored on your device. Your Kindle books will remain on your device until you delete them.
Kindle books are stored on the device in an electronic library. The Kindle uses a proprietary format to manage the files. It is believed that the DRM code for these files is stored in an external location, which means that no Kindle books are stored on the device itself.
On a Kindle, a Mobi file is a digital book that can be read on the device. The files are encrypted and cannot be transferred from the device to another device. One way to locate Mobi files on a Kindle is to use the Manage Your Content and Devices option from the browser menu. This will open a window of all of your content on your Kindle where you can select the title of the book you are interested in reading.
To retrieve content from iCloud, navigate to the “iCloud Drive” folder in Finder or Windows Explorer. Select the desired files. Right-click on the selected files and select “Open in Kindle for PC.
The answer to the question is that you can download your pdf off of your Kindle Cloud by accessing your account and then selecting the download button on the title. This will download a copy of the pdf onto whichever device you are using as long as it has access to the internet.
