Everything You Need
Built from the ground up for privacy, resilience, and ease of use.
End-to-End Encrypted
Every message is encrypted before leaving your device. Relay phones never see your content.
Offline Mesh Network
Messages hop through nearby Zylo users to reach their destination — no internet needed.
Invisible Relay
When your phone relays others' messages, you see nothing. No notifications, no chats — completely silent.
Bluetooth + WiFi
Use Bluetooth, WiFi Direct, or both for the best range and fastest connections.
Image Sharing
Send photos through the mesh. Images are compressed, encrypted, and delivered securely.
Message Expiry
Messages automatically delete after your chosen time — 2h to 92h — on every device.
Mesh in Action
Your message hops through nearby phones until it reaches its destination.
Register Once
Create your account with email. Your device gets a unique cryptographic identity.
Find Nearby Users
Scan for nearby Zylo users via Bluetooth/WiFi. Send a chat request.
Chat Privately
Messages are encrypted and travel through the mesh. Only you and your recipient can read them.
We Never Read Your Messages
All messages are end-to-end encrypted. Our server only handles account authentication. Your conversations never touch our servers.
