MeshWalk - Offline Mesh Chat

MeshWalk turns your phone into a node in a local mesh network, letting you chat with people nearby — no internet, no cell towers, no servers. Messages hop between devices using Bluetooth and Wi-Fi Direct, creating a self-organizing communication network that works anywhere.

HOW IT WORKS

Every device running MeshWalk becomes a relay point. When you send a message, it travels from phone to phone until it reaches the recipient. The more people use it, the stronger the network becomes. Messages can travel multiple hops, extending your reach far beyond direct Bluetooth or Wi-Fi range.

WHEN YOU NEED IT

• Festivals, concerts, and crowded events where cell networks are overloaded
• Hiking, camping, and outdoor adventures with no signal
• Natural disasters and emergencies when infrastructure is down
• Travel in remote areas without reliable connectivity
• Schools, offices, and buildings with poor reception
• Privacy-conscious communication without relying on centralized servers

SECURITY FIRST

Your privacy is not optional — it is built into the architecture:

• End-to-end encryption with AES-256-GCM on every message
• ECDH P-256 key exchange and ECDSA P-256 message signing
• Cryptographic keys stored in Android Keystore with hardware backing
• No data ever leaves your device to any server
• Relay nodes cannot read messages they forward
• No analytics, no tracking, no ads — zero telemetry

IDENTITY OPTIONS

Choose how you want to be known on the mesh:

• Named identity — pick a display name others can recognize
• Anonymous identity — communicate without revealing who you are
• Temporary identity — auto-expires after 24 hours for one-time use

YOUR DATA STAYS WITH YOU

MeshWalk has no backend servers. All messages, keys, contacts, and routing data live on your device and nowhere else. When you uninstall the app, your data is gone. We cannot access, read, or recover your messages — by design.
