Android/desktop: use Install Magnus app when available. iPhone/iPad: Safari Share menu → Add to Home Screen. Offline mode preserves the app shell and local archive; report generation and cloud sync still require network access.

End-to-end encryption: dictation, prior, report, labels, notes, and case metadata are AES-GCM encrypted in this browser before upload. Supabase stores ciphertext only. The encryption passphrase and Supabase password are never persisted.

Reports are stored in IndexedDB independently of the active worklist. Clearing completed/worklist cases does not erase the permanent archive.
