Do you trust messaging apps that claim even their own company can't read your messages?
MessageVAX released version 3.0 of its messaging app on Google Play in 15 countries, and submitted an iOS version to Apple for App Store review. The release is the company's first public version after five years of development.
Why it matters
The release adds another encrypted messaging option with post-quantum key establishment and a credit-based model without advertisements or third-party advertising trackers. Its design keeps readable conversation history on the user's device rather than on the server.
Version 3.0 uses X448 key agreement, ML-KEM-1024 post-quantum key establishment, HKDF-SHA-512 key derivation and AES-256-GCM authenticated encryption. Independent verification of these implementations was not reported.
The players
MessageVAX
MessageVAX is a Sydney-based company that develops an encrypted messaging application with a credit-based payment model.
Superclass
Superclass is the company base associated with MessageVAX's headquarters in Sydney.
The details
Messages are encrypted on the user's device with keys generated there and used once for a single message. The server relay, called the Post Office, stores delivery items only until they are collected or expire, and version 3.0 adds TTL settings, Burn After Reading, Burn After Send, Amnesia and Eject tools.

The Tech Race
MessageVAX's use of ML-KEM-1024 places a consumer messaging app alongside the post-quantum standards NIST finalized in 2024. The release extends that standard into a mass-market product rather than only enterprise or government systems.
Users can download version 3.0 from Google Play in the 15 supported countries, with 20 welcome credits given on first download. The app's credit model means ongoing use is paid rather than funded by advertising.
The takeaway
Readers choosing a messaging app can compare where message history is stored and how keys are generated, since those choices determine who can access conversations. Checking whether a provider publishes independent audits can help separate stated security from verified security.
