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.

Not working with Nextcloud even though it says it does. There's no support, they never replied to my emails for two weeks and counting now. Update: Got it to work by continuously wiping data for the app and retrying. Seems like a bug. Keeping the rating low because the developer does not reply to support emails.

Copied my Calibre database from OneDrive to pCloud. Syncing working faster now. However, with the latest Calibre Sync update (6.6.0+267) the library is no longer syncing. New books added are not showing, but I am still able to retrieve the books that are showing. Sync info showing last sync Oct 19 (two days ago).

Contacted support about with these issues but got no response. Been downloading 7000 books for about a month all night every night and some days. Ridiculously slow. This app is on my Kindle. When I open books the app says drm protected. They are not. I can open them on my Kindle with no problem. Wishing for calibre companion to be supported again( sigh).

I really wanted to like this app. Unfortunately, it didn't work for me. I made a wireless connection from an Android tablet to a Windows laptop running Calibre. The library has about 9000 books. It failed after transferring a few hundred but Calibre indicated that many more were. This was confusing. The transfer speed per book was also slow. I uninstalled and reverted to Calibre Companion. Calibre Sync isn't ready for prime time yet.

Incredibly powerful app and just what I was looking for! The developer is actively working to make this app better with each release and incorporatesany of the suggestions and requests into new versions. I emailed requesting some support and they replied within two days. Awesome! I have 1400+ books in my library and use the Calibre server option. Quick to search and find books that I want to put on my device. For those wanting sync-read-position -> moon+ reader is it.

I'd been a long-time Calibre Companion user; it took me some time to get used to Calibre Sync's interface. It's grown on me. I used CC's wireless device connection exclusively; CS's is not quite as good, but makes up for it in its content server interface. I'm now fully switched to that. I appreciate that the developer responds to customers and continues to improve this app.

I had used an older app for years to access my cloud library. I didn't realize the new developer had ghosted that app until I switched to a newer phone. Calibre Sync has everything I need, and more. Right off the bat, I can tell you this: Easy search, easy share... Just EASY. The GUI is clean and easy to use. I can't wait to explore its capabilities in full I wish I had found this app years ago. Thank you for this app!

Wow, I just finished battling with a different, more expensive, Calibre Android app tool, and Calibre Sync is so much more polished in comparison. I have encountered crashes when fast scrolling through my 600+ book collection but other than that it works well to download books onto my device. I wish the filtering was streamlined; I make heavy use of Series and it requires many clicks to browse. I hope this app keeps getting updates! Please update the screenshots: night mode on tablet is beautiful!
