Why use Yantagram?

Traditional messaging apps depend on centralized infrastructure that can be monitored, censored, or disabled. Yantagram is a peer-to-peer messaging application that operates over bluetooth mesh networks. No internet, servers, or phone numbers required. Internet connectivity is available to extend range when you want it.

01

Ultimate Privacy

Yantagram has no central servers. Your identity and data is stored on your device only.

02

Messages Traverse the Mesh

Your encrypted message hops between nearby devices with Yantagram installed. Each relay extends your reach without ever decrypting your message. The network remains functional during internet outages, natural disasters, or in regions with limited connectivity.

03

Internet Connectivity Available

Yantagram can use a relay server to send messages over the internet. Messages are always end-to-end encrypted and no data is permanently stored on the server. The relay server can be disabled in settings.
