About this app
ARX: The Private Super App for Secure Communication & Connectivity
ARX is a privacy-first app with end-to-end encrypted messaging, global eSIM data, and an encrypted vault. One app. No phone number or email required — your keys stay on your device.
Private messaging, first
End-to-end encrypted chats, voice, and video powered by advanced cryptographic protocols. Groups, voice notes, files, and live location, private by default. Optional disappearing messages, mutual screenshot consent, and a duress code keep you in full control.
Global eSIM
Get online in 190+ countries with no physical SIM. Buy and manage instant mobile data plans directly inside the app.
ARX Vault
Keep your sensitive notes, files, photos, and login credentials protected on your device with local encryption.
Privacy by design
Your account is secured by unique encryption keys stored locally on your device, with PIN, biometrics, and duress PIN support. We cannot read your end-to-end encrypted messages. See our Privacy Policy for how optional, anonymous analytics help improve the app.
Your messages and your data. In one secure, independent app.
