Sync settings

Sign in with the same Google account on Android and Windows. Changes saved offline are queued for synchronization when internet returns.

Local mode

Google sign-in requires internet. Offline use works after the app has been opened and cached on your device.

Backup

Export a backup regularly to G:\sell\Backups on Windows. Browser storage is not a permanent backup; don't clear site data with unsynchronized changes.
