Having gone through PrivacyTool’s recommendations, I am starting to transition away from iCloud services. This is made rather easy since I already had a webdav solution. One outstanding element is Apple Book (formerly iBooks).
First question: is Apple Book really part of iCloud? It does not show up on iCloud options, but if it syncs between devices, there must be a link somewhere.
Second question: what can I replace it with? On the mac end, it’s rather straightforward, as a simple folder structure with Preview does the trick (at least in an ok manner). But what about the iPhone side? Any recommendations for a (preferably free and open-source) app that can manage some PDFs and e-books and sync with a webdav server?
I have so far read about Goodreader, but it is neither free nor open-source and the licence agreement is not encouraging regarding the use of my data.
Thanks in advance for any recommendation/advice!
