OffMesh: Offline Chatting

OffMesh is an autonomous, peer-to-peer, encrypted mesh messaging application that operates entirely without cellular networks, internet connectivity, or centralized servers. Whether you are hiking off-grid, traveling abroad without a data plan, navigating natural emergencies, or communicating in dense crowds with congested cell towers, OffMesh keeps you connected. KEY FEATURES: • TRUE OFFLINE MESH NETWORKING: Transmit messages device-to-device using Bluetooth Low Energy (BLE) and Wi-Fi Direct. • DOUBLE RATCHET END-TO-END ENCRYPTION: Military-grade cryptographic privacy with per-message forward secrecy and break-in recovery. • STORE-AND-FORWARD RELAYS: Intermediate devices seamlessly relay encrypted packets across multi-hop paths without ever decrypting their contents. • SELF-SOVEREIGN IDENTITY: No phone numbers, no emails, no SIM cards required. Identity is backed entirely by on-device cryptographic keypairs. • OUT-OF-BAND VERIFICATION: Scan safety numbers and contact cards instantly via high-density visual QR codes. • HONEST DELIVERY FEEDBACK: Explicit delivery indicators: Queued (Local), In-Mesh (Relayed), and Delivered (Cryptographic ACK). • ZERO TRACKING & ZERO TELEMETRY: Zero analytics, zero logging, and zero corporate data harvesting. OffMesh is free, privacy-first, and fully independent.
