Backup & restore
Your notes, favourites, diary and matters live in this browser. A backup is one file you keep - and it is the same format as the Android app's, so it moves between the two.
In this browser
From the Android app
In the app open Settings → Backup & Restore → Save a backup, send the file to this device, then choose Restore from a file here. Your premium unlock is not in the file.
Restoring never deletes
A restore adds what is missing. Anything already here with the same id is left as it is, so an old file cannot undo newer work.
