End-to-end encrypted messaging with P2P calls. Your conversations stay private, exactly as they should be.
Android 7.0+ • 1.0.0 • build 5
Orpheus is designed for hostile environments where the threat targets the person, not just the network.
No phone number. No email. Your identity is a cryptographic keypair generated on-device.
Contacts are exchanged directly (e.g. QR). Infrastructure can’t reconstruct your connections.
Messages and contacts live on the device. Servers relay encrypted packets, not your history.
Plausible-deniability behavior under coercion: the app can appear normal yet reveal nothing sensitive.
Fast local destruction of keys and data when keeping information becomes a direct risk.
Calls are established via signaling, then audio flows directly between devices.
