There is an option - to use Googledrive or OPDS storage as a library.

Answer 1

Only the LitRes e-book store program meets the specified requirements. The Android application allows you to upload books to your personal database, and then shows the bookmarks in the browser version.
For all other readers, Caliber must be installed on a local machine that uses the OPDS server . The
Moon + Reader application came closest, in conjunction with Caliber - there you can convert bookmarks separately from the text of the book into applications like OneNote. Only here you can set up opds Caliber - you can only on the local network, but in order to read books and make bookmarks somewhere outside the local network at home - you need an external IP address, and this is an additional cost to rent a static IP address from the provider.
