Lumen Mesh: Off-Grid Messenger

Stay Connected When the Grid Fails.

Lumen Mesh is a decentralized, peer-to-peer (P2P) communication tool. Whether you are in the wilderness, attending a crowded event, or preparing for network blackouts, Lumen Mesh keeps you communicating when traditional networks are unavailable.

No internet, no cell towers, and no SIM card required.

By utilizing your device's built-in Bluetooth and Wi-Fi Direct capabilities, Lumen Mesh links smartphones together to form a resilient, self-healing mesh network. Messages hop from device to device until they reach their destination.

🛡️ ZERO TRUST, MAX SECURITY

Privacy is the baseline. Lumen Mesh does not use cloud servers, requires no phone number, and asks for no email registration. All communications are secured using AES-256-GCM encryption and Elliptic Curve Diffie-Hellman (ECDH) key exchanges. Your data never leaves the mesh and remains stored only on your device inside an encrypted local database.

⚡ CORE FEATURES

Offline Messaging: Send secure text messages to nearby nodes in the mesh network.

Image Transmission: Share critical photos locally without a data plan.

Decentralized Architecture: No central servers or single points of failure.

Auto-Routing: Messages automatically hop across intermediate devices to extend range.

No Accounts Required: Select an Operator Alias and start communicating immediately.

🎯 INTENDED USE:

Outdoor Exploration: Hiking, skiing, and off-roading in zero-coverage areas.

Large Events: Communicate with your group when crowds overload local cell towers.

Tactical Coordination: Coordinate securely in the field without relying on public radio frequencies.

Emergency Preparedness: Stay connected with neighbors during severe weather or power outages.

💎 ADVANCED TACTICAL FEATURES

Advanced capabilities are available for specialized operations:

Background Service: Maintain the mesh network while the app is minimized. Receive incoming messages and relay data for others even when the screen is locked.

Stealth Mode: Obfuscate your Node ID from public broadcasts and rotate cryptographic footprints to maximize Operational Security (OPSEC).

Custom Network Keys: Create a private, isolated subnet. Only devices utilizing your exact Pre-Shared Network Key can join or decrypt traffic, protecting from unauthorized bridging.

⚠️ IMPORTANT NOTE ON PERMISSIONS:

To utilize Bluetooth and Wi-Fi Direct for P2P connections, the Android operating system requires the "Location" and "Nearby Devices" permissions to be granted. Lumen Mesh does NOT track, store, or share your GPS location. The permission is used by the OS solely to discover other devices in your physical proximity.
