With Share the books too on, LuceVoce copies your books into your sync folder, and your other devices add them to their library by themselves. Open one there and LuceVoce offers to continue from the place you reached.

Turn on book sharing

  1. Turn on sync and choose a folder on each device. See Continue reading on another device.
  2. In Settings > Sync, turn on Share the books too.
  3. Do the same on your other devices, so that they share their books too.

Keep this folder private. If the folder is shared with other people, they get your books as well.

Choose which books are shared

Under Which books, choose one:

  • Books I have started: only books you have begun reading or listening to. This is the starting choice.
  • All my books
  • Only the ones I choose

Whatever you choose here, you can decide for each book. In the library, open the book's More actions menu and tick or untick Share with my other devices.

A book that stops being shared, because you unticked it or changed Which books, is taken out of the folder once no other device shares it.

Audiobooks

Audiobooks are not shared unless you turn on Audiobooks too. An audiobook takes hundreds of MB of cloud storage. The switch also decides whether this device takes in the audiobooks that your other devices share. An audiobook made of a folder of separate tracks is never shared.

Voices you added

Voices you added from a file can travel too.

  1. In Settings > Sync, turn on Share the voices I added too. Each voice is copied to the sync folder (60 to 110 MB each).
  2. On your other devices, Settings > Sync lists them under Voices on your other devices. Choose Get the voice to install one there.

A voice for personal use only is for your own devices. Removing a voice on one device never removes it from another.

On mobile data, a voice waits for Wi-Fi unless you choose Use mobile data.

Save mobile data

Download only on Wi-Fi is on at the start. On mobile data, books from your other devices wait, and the library says how many are waiting and how much they weigh:

  • Choose Download now to fetch them anyway.
  • When you choose one book by hand, its row offers Use mobile data.

On a Windows PC, a connection marked as metered, such as a phone hotspot, counts as mobile data.

Books from your other devices

Shared books come into your library one at a time, without opening. While they arrive, they are listed under On your other devices at the end of All books, with the device they come from, the format, the size and how far you got there.

If you remove a shared book from a device by hand, it doesn't come back. It stays listed under On your other devices with Download, in case you want it again.

Good to know

  • Each book is copied into the folder only once, even when several devices have it.
  • When you remove a book from your library, it is taken out of the folder once no other device shares it.
  • If a book you added from another folder goes missing, LuceVoce restores it from a copy that another device shares, keeping your place, notes and bookmarks.
  • Books protected by DRM are never added to the library, so they are never shared.
  • Shared books count against the storage of your cloud service.
