VantaChat — Private Messaging, Reimagined

VantaChat is a secure messaging app built for people who take their privacy seriously. Every message, call, and file you share is protected with end-to-end encryption before it even leaves your device — ensuring that only you and your intended recipient can access it.

No backdoors. No data mining. No compromises.

🔐 True End-to-End Encryption

Your privacy is the foundation of VantaChat.

All messages — whether one-on-one or in groups — are encrypted directly on your device using AES-256-GCM, with secure key exchange powered by Elliptic Curve Diffie-Hellman (ECDH).

Your private keys:

Are generated on your device

Stored securely in the Android KeyStore (hardware-backed where available)

Never leave your device

This means your conversations are completely inaccessible to anyone else — including us.
