Back up
The shelf lives in this browser. Keep a copy on this device, or send the same file to a cloud account.
Opening your shelf…
On this device
Waiting for the shelf.
This browser can't pick a folder, so it can't write straight to an SD card. Save to phone, then move the file onto the card with the Files app.
This browser has no share sheet for files.
Email a backup to myself
A web page can't attach the file for you. It downloads, then your mail app opens so you can attach it.
Restore
Merge keeps both shelves and lets the newer copy win. Replace removes what is on this device first. A cloud backup uses the same choice.
Cloud
Dropbox, Google Drive, OneDrive, and pCloud appear when their public client ids are set. WebDAV uses an address and app password you enter here.
Google Drive
A Music Ledger folder in your Drive. The app only sees files it created. The token stays on this device.
WebDAV
Nextcloud, ownCloud, or a NAS. The address and app password stay on this device. The server has to allow this site, or the browser will refuse the connection.
Automatic backup
Off unless you turn it on. When the last backup is more than 14 days old, opening the app saves once to the account you pick. An expired Google sign-in waits until you connect again instead of opening a window on its own.
