Cloud backup toggle, off by default. A new “Cloud backup” switch in Settings → Backup lets you choose whether your encrypted wallet file is included in your phone’s normal system backup — iCloud on iOS, Google Drive (Android Auto Backup) on Android. It stays off unless you turn it on yourself; when off, the database is explicitly excluded from both. This setting is re-checked every time the app starts, so it can’t silently drift back on.
Fixed
Wallet database “disappearing” after upgrading from the old NS Wallet (5.x) app. The previous Xamarin-based app stored its database in a different folder convention than the current app expects. A one-time migration now runs automatically at startup, safely moves the old database (and its journal files) to the new location, verifies the copy, and only then removes the original.
Compatibility
Updated to the current file-picker API used for backup import/export.
