Privacy-first design with end-to-end encryption and no analytics
Offline mesh messaging via Bluetooth allows communication without internet
Multi-path transport layers (Bluetooth mesh, libp2p, Nostr Relay) for resilient reach
No accounts or central servers simplify onboarding and enhance user control
Offline mesh reliance on nearby devices may limit reach in sparse areas
Mainstream feature parity with centralized messengers can be lower (no traditional server-based flows)
Permission prompts (Bluetooth, location, camera, mic) are necessary for full functionality

Description
Zemzeme - Private messaging that doesn't need the internet to work.
No account. No phone number. No central server. Just open the app, pick a nickname, and start talking. Every message is end-to-end encrypted - always.
Most messengers stop working when you lose signal. Zemzeme doesn't. It uses Bluetooth mesh networking to send messages through nearby devices - no Wi-Fi, no mobile data, no internet required. When you do have connectivity, two additional transport layers activate automatically for global reach.
Three transport layers, working simultaneously:
★ Bluetooth Mesh - Messages hop between nearby devices using Bluetooth LE. Works in airplane mode, underground, in rural areas, or anywhere there's no signal. Perfect for festivals, emergencies, travel, and off-grid communication.
★ Peer-to-Peer (libp2p) - Direct encrypted connections over the internet. No middleman server. Powered by libp2p, the same protocol used by IPFS and Ethereum.
★ Nostr Relay - Decentralized relay-based messaging for maximum reachability when direct connections aren't possible.
The app automatically routes messages through whichever paths are available and falls back seamlessly.
Built for privacy: • End-to-end encryption on every message (Noise Protocol - Curve25519 + ChaCha20-Poly1305) • No registration, no phone number, no email • No analytics, no tracking, no ads - ever • No data leaves your device unencrypted • Optional Tor routing for network-level anonymity • Verify contacts by scanning their QR code (Ed25519 signed) • PIN + biometric app lock
What you can do: • Send text messages with @mentions • Record and send voice notes • Share images and files of any type • Join location-based public channels (city or country scale) • Create password-protected group chats • Verify peer identities with QR codes • See read receipts and delivery indicators • Relay messages for others on the Bluetooth mesh automatically
Use cases: • Music festivals and crowded events with no signal • Natural disasters when cell towers go down • Travel in areas with limited or no connectivity • Privacy-conscious everyday messaging • Communities wanting communication free from centralized control • Off-grid and outdoor adventures
How it works: 1. Open the app — no sign-up required 2. Grant Bluetooth and location permissions 3. Choose a nickname 4. Start messaging - nearby Zemzeme users appear automatically on the mesh 5. Tap + to join a location channel or start a private chat
Zemzeme is open source and built on proven cryptographic libraries. Your privacy is not a feature - it is the foundation.
