Notes: - Calibre Sync is not a reader app. You must install and use one of the many excellent reader apps available. - Only Microsoft OneDrive for Personal accounts (shared) are supported. Please email us if you observe any inconsistencies. - Due to restriction in Box API, Calibre Sync must acquire write permission in order to download files, download is not a read action on Box. Calibre Sync guarantees that it will not perform any write actions against your data in Box cloud account. - Calibre Sync use WebDav API of Nextcloud and OwnCloud services, and it requires case sensitive file system to work properly. Therefore, you must make sure that your libraries are set up on case sensitive file system (Linux, recent MacOS, Windows NTFS with case sensitive enabled). Permission explanation: - Calibre Sync only requires "storage permission" to store downloaded book formats on your device. *For Lollipop devices* you must have sdcard available so that the app can download books to external storage.

Problem with notifications and covers download - I have all my libraries on Pcloud USA. First, Android blocks all notifications from this app and I don't understand why. Second, app fails to download a lot of book-covers with error "NoSuchMethodError" The getter first was called on null. Calibre Sync does not respond to emails. Very disappointed.

Doesn't recognize the books saved locally to my SD card. I wanted a replacement for the excellent Calibre Companion app that they've made unusable, but this ain't it.

Habe die App neu und fand sie erst toll. Calibre auf Laptop, Bib ebenso. Sync mit OneDrive, online alle Daten aktuell. Neue ebooks hinzugefügt, online auf OneDrive per Sync vorhanden. App mit OneDrive snychronisiert (automatisch u. händisch): neue ebooks nicht vorhanden. App gestoppt, Cache geleert: bringt nichts, App aktualisiert nicht aus OneDrive. Murks, so ist die App nicht brauchbar. Nachtrag: auch via Calibre Inhalteserver Sync ohne neue ebooks, nur alles neu einlesen hilft. App fehlerhaft

Ich habe die App frisch gekauft und fand sie anfangs toll. Calibre auf Laptop, Bib ebenfalls dort. Synchronisation mit OneDrive, online alle Daten aktuell vorhanden. Neue ebooks hinzugefügt, online auf OneDrive per Synchronisation vorhanden. App - mit OneDrive verbunden - snychronisiert (automatisch und händisch): neue ebooks nicht vorhanden. App gestoppt, Cache geleert: bringt nichts, die App aktualisiert nicht aus OneDrive. Das ist Murks, so ist die App nicht zu gebrauchen.

nutze Calibre Sync mit Onedrive. Einrichtung und Synchronisation absolut problemlos und intuitiv nutzbar, würdiger Ersatz für CC.

App goes back to the select a library screen. No matter what I do the app is unusable. I have logged into my Dropbox and Drive accounts and none of them work .

This is a good app that hasn't been updated for a while. Windows Calibre Version 8.12 removed the RECOVER_PARSER function, which disables this app from accessing your library. Until Calibre Sync is updated, stay with Calibre version 8.11.1 which works fine.

Does what I need it to do (download wirelssly via calibre content server) with a nice GUI. However it was a bit cumbersome to delete my existing transferred Calibre books folder and re-download everything through the app in order for it to recognize which books I already had on my device.
