Progressive audio
Real waveform visualization with progressive playback while receiving and full seeking after completion.
On-device translation
Local language identification and downloaded translation models let you translate messages inside Hashi.

SECURITY ARCHITECTURE
Security is part of the design, not a badge added later.
Hashi uses Android Keystore-backed identity material, authenticated short-lived API sessions, AES-256-GCM protected payloads, contact key-change detection and encrypted local stores for sensitive app data.
