Noghteha

This Mesh Messenger Keeps You Connected When the Internet Fails

Noghteha is a privacy-first mesh network messenger that lets you communicate when the internet is unavailable or unreliable. It builds a resilient local network using Bluetooth and WiFi Aware, so your messages seamlessly hop from phone to phone. Whether you're at a festival, on a university campus, traveling through areas with weak coverage, or preparing for emergencies, this offline messenger keeps you chatting. When global reach is needed, an additional online mode routes traffic through Tor and the Nostr protocol, all without changing your habits.

Offline Mesh Messaging for Everyday Use

This peer-to-peer chat tool connects nearby devices within 10 to 100 meters via Bluetooth and approximately 50 meters via WiFi Aware for faster transmissions. Messages automatically relay through people around you, so a short chain can cover surprising distances. No need to set up a phone number, email, or account—your identity stays local on your device, with rotating Bluetooth addresses to reduce tracking. Create public rooms for open discussions or use password-protected channels for small groups, and keep chatting even when cellular service drops.

No Ads and Turbo Benefits

Enjoy an ad-free experience with additional advantages through Turbo mode. This ensures uninterrupted, fast messaging without any commercial interruptions.

Security and Privacy by Design

Every conversation is encrypted end-to-end using the Noise Protocol XX handshake with ChaCha20-Poly1305, and perfect forward secrecy protects past messages if keys are later compromised. Channel passwords are strengthened with Argon2id. Local data is stored in an encrypted database using SQLCipher with AES-256, with hardware-backed key storage via Android Keystore with StrongBox when available. Panic mode wipes all app data with a single tap, using three-pass secure deletion, while multi-layered stealth modes reduce Bluetooth visibility to keep Noghteha discreet.

Rich Chat Features and Polished Design

Beyond reliability, this secure group chat app feels fully featured. Send text with mentions, record voice notes with waveform visualization, share images or files up to 100 MB, reply in threads, and see link previews. Location-based channels help you connect with people nearby, while familiar IRC-style commands like /join, /who, or /msg simplify advanced use. Right-to-left languages are fully supported with the Vazirmatn font, plus light or dark themes and Material You colors on Android 12 or newer.
