Security Architecture & Specification

Mathematics and cryptography enforce your privacy. Server relays are untrusted by design.

1. Zero-Knowledge Server Relays

Messages are routed in transient RAM only. Once delivered to recipient, messages are instantly purged from relay memory.

2. Client-Side Key Generation

Private keys are generated on device hardware and never transmitted to any server. Your keys stay in local Android/iOS keychains.

3. Play Integrity Attestation

Device integrity checks block modified client binaries, rooted devices, and tampered APKs from accessing network endpoints.
