🛡️ Security & Cryptographic Trust

Security & Privacy Architecture

Technical overview of Vynqo’s End-to-End Encryption and Zero-Knowledge principles.

Version: v1.0.0 • Effective Date: October 3, 2026

1. Cryptographic Foundation

Vynqo 1-on-1 private messaging is built using the Signal Protocol cryptographic standard (Double Ratchet Algorithm, Curve25519, AES-256-GCM, and SHA-256). No intermediary, including Vynqo servers, holds the private keys.

2. Agora RTC Real-Time Calling Security

Voice and video calls use Secure Real-time Transport Protocol (SRTP) point-to-point encryption, providing crystal clear HD audio/video with sub-100ms latency and no server-side recording.

3. Local Device Security & Biometric Lock

Users can protect their app access using Android BiometricPrompt (Fingerprint / Face Unlock) and enable automatic cache purging for expired stories and media.
