NoxRail creates a mesh network between devices. No internet, no cell towers, no servers. Just secure, peer-to-peer communication that actually works.
Remote areas, basements, festivals, disasters - traditional messaging fails when you need it most.
Every message goes through corporate servers. Your private conversations aren't really private.
Metadata reveals who you talk to, when, and where. Even "encrypted" apps leak this data.
No servers. No internet. No metadata. Just pure, peer-to-peer communication.
Powerful features designed for real-world scenarios
Messages hop between devices automatically. If you can't reach someone directly, nearby NoxRail users relay your message. No internet needed.
Text, photos, videos, voice messages, locations, polls, and more. Everything you expect from a modern messenger.
Crystal-clear calls over the mesh network. Works peer-to-peer without any servers.
Create groups with admin controls, shared media galleries, and invite links.
Share your location in real-time or as a static pin. Perfect for meetups and emergencies.
Share photos and videos that disappear in 24 hours. Just like you're used to.
Leave digital messages in physical locations. Others can discover them when nearby.
The most secure messaging app you can use
End-to-End Encrypted
X3DH + Double Ratchet encryption. The same protocol trusted by journalists and activists worldwide.
No data ever touches a server. No cloud. No backups we can access. Truly peer-to-peer.
Get alerted when someone screenshots. Sensitive chats are protected from screen recording.
Set messages to auto-delete. Your conversations leave no trace.
For when privacy isn't optional. Ghost Mode transforms NoxRail into a fully functional calculator. Only you know it's a messenger.
Looks and works like a real calculator
Enter your PIN as a calculation to unlock
Emergency PIN wipes all data instantly
Disappear from the mesh network completely
When every second counts. One tap sends your GPS location to every NoxRail user nearby. Audio alarms. Flashlight strobe. Maximum mesh propagation.
NoxRail continuously scans for other NoxRail devices nearby using Bluetooth Low Energy. No pairing required.
When two devices connect, they exchange encryption keys using the X3DH protocol. All future messages are end-to-end encrypted.
If the recipient isn't nearby, your message hops through intermediate devices until it reaches them. Each hop is encrypted.
When the message arrives, you get a delivery receipt. The entire journey happens without touching the internet.
When cell networks are overloaded, NoxRail keeps you connected with your group.
Hiking, camping, skiing - stay in touch even in remote areas with no signal.
Basements, bunkers, underground parking - mesh works where cellular doesn't.
Natural disasters, power outages - NoxRail works when infrastructure fails.
No roaming charges, no local SIM needed. Connect with fellow travelers directly.
Journalists, activists, anyone who needs truly private communication.

Finally, a messenger that doesn't require me to trust a server. NoxRail is what Signal should have been - truly decentralized.
Used NoxRail at Burning Man - no cell service but we stayed connected with our entire camp. Game changer!
The Ghost Mode feature is genius. As a journalist, having plausible deniability is crucial for source protection.
Our hiking group relies on NoxRail for backcountry trips. The SOS feature gives us peace of mind when we're off-grid.
NoxRail uses Bluetooth Low Energy to create a mesh network between nearby devices. When you send a message, it hops from device to device until it reaches the recipient - no internet, cell towers, or servers required. Think of it like a digital relay race.
Each device-to-device connection has a range of about 100 meters (330 feet) in open areas. But here's the magic: messages can hop through multiple devices, so the effective range is unlimited as long as there's a chain of NoxRail users between you and the recipient.
Yes! NoxRail uses the same encryption protocol as Signal (X3DH + Double Ratchet) with AES-256-GCM encryption. Every message is end-to-end encrypted, and because there are no servers, there's no central point of attack. Your messages are decrypted only on the recipient's device.
Ghost Mode disguises NoxRail as a fully functional calculator app. You unlock it by entering a secret PIN. There's also a "duress PIN" - if you're forced to unlock the app, entering this PIN will securely wipe all data while appearing to work normally.
NoxRail uses Bluetooth Low Energy, which is designed for minimal battery consumption. The app also has battery optimization features that reduce scanning frequency when your battery is low. Most users report minimal impact on battery life.
Absolutely! While the mesh network shines with multiple users, NoxRail works perfectly for two-person communication. As long as you're within Bluetooth range of each other (or there are NoxRail users in between), you can communicate securely.
Yes, NoxRail is completely free to download and use. There are no in-app purchases, no subscriptions, no ads, and no data collection. We believe privacy should be accessible to everyone.
Yes! NoxRail is fully open source. You can audit the code, contribute improvements, or fork it for your own use. Transparency is fundamental to trust, especially for security-focused software. Check out our GitHub repository.
