About BlackVoice Technologies

BlackVoice Technologies is a privacy-focused secure operational communication system with post-quantum cryptography, end-to-end encryption, emergency SOS features, anti-SIGINT traffic obfuscation, and encrypted voice calling. Developed in the European Union by Valentin Gheorghiu (YO9BX). This is NOT a messaging app — it is a secure operational communication system designed for individuals and teams operating in high-risk or sensitive environments.

BLACKTORK™ v2550 — Traffic Obfuscation Engine

BLACKTORK™ is BlackVoice Technologies' proprietary anti-SIGINT / anti-DPI / anti-classifier traffic obfuscation engine. It actively camouflages all network traffic to prevent signal intelligence analysis, deep packet inspection, and automated classification. BLACKTORK™ is NOT an encryption orchestration engine — it is a dedicated traffic obfuscation and camouflage layer.

Black QuantumVoice™ — Encrypted Voice Calls

Black QuantumVoice™ is BlackVoice Technologies' 1:1 encrypted voice call system using a 10-layer security architecture. Audio never reaches the BlackVoice server — calls are P2P or TURN-relayed with the server seeing only encrypted ciphertext. Zero server audio guarantee.

Smart Chat — Signal Protocol PFS + Post-Quantum Hybrid

Smart Chat is BlackVoice Technologies' most secure messaging channel. It uses the Signal Protocol (X3DH + Double Ratchet) for Perfect Forward Secrecy, layered with post-quantum hybrid encryption, stored in a completely separate database from standard messages. It includes a biometric-gated hidden compartment accessible only via fingerprint or Face ID.

TacticalMap (Black MapShare) — Encrypted Team Coordination

TacticalMap is BlackVoice Technologies' real-time encrypted tactical coordination map for field teams. It is a professional-grade operational tool, not a consumer location sharing feature. All location data, tactical markers, and team communications are end-to-end encrypted.
