Product Identity
Privacy First
E2EE is free for everyone. No backdoors. No metadata harvesting. Client-side Sealed Sender hides even the sender from our servers.
Post-Quantum Ready
ML-KEM-1024 hybrid key exchange protects against future quantum computer attacks. NIST FIPS 203 certified, Level 3 security.
Offline Capable
BLE Mesh Network enables encrypted communication without internet via Bridgefy SDK encryption. The BLE range limitation (10-30m) provides an additional physical security layer. Essential for disaster scenarios and remote areas.
Wine Community
Arc targets wine lovers and winery professionals with Winery Mode for field work management, combining privacy with community.
AI Characters & On-Device AI
6 cloud AI characters plus on-device AI powered by DeepMind's Gemma 3n β AI pets and Rosetta offline translator that run entirely on your phone, completely private and offline.
Security Without Compromise
Signal Protocol as the foundation, enhanced with three proprietary security layers.
Multi-Layer E2EE
PQCPQXDH (X25519 + ML-KEM-1024) key exchange, Double Ratchet, AES-256-GCM encryption, AEGIS XEdDSA message signatures, and Client-Side Sealed Sender.
Mesh Network
BLE-based offline communication protected by Bridgefy SDK encryption. The BLE range limitation (10-30m) adds a physical security layer. No internet required β ideal for disaster scenarios and remote areas.
IGF (Ignite the Fire)
Our proprietary timed-deletion system. Messages are completely erased from all devices and servers β gone forever.
Key Sync
Securely transfer encryption keys between devices using QR codes. X25519 ECDH + AES-256-GCM encrypted transfer with 5-minute session TTL.
AEGIS Signatures
XEdDSA per-message digital signatures via libsignal prevent impersonation and tampering. AEGIS (Arc Enhanced Guard & Integrity System) provides cryptographic non-repudiation on every message.
Sealed Sender
Client-side sender anonymization. Even the server cannot see who sent a message. Ephemeral X25519 key per message + HKDF-SHA256.
AI Summary
AILong-press any message with a URL or PDF to get an instant AI-powered summary by Gemini β without opening the link. Summaries are cached for 24 hours. Available for Premium and Intelligence plans.
