End-to-end encrypted messenger
Private by architecture, not by promise.
Encrypted messages, calls, and files. No phone number, no email, no trace left on our servers.
Google Play coming soon — install the APK directly for now.
Built on Zero Trust
Privacy is enforced by technical design, not by company policy.
No phone or email
Create an identity without handing over a phone number, an email, or a name. Less data collected means less to leak.
Contact-only reach
You can only be messaged by people you've exchanged contacts with. No discovery, no directory, no cold contact.
A server that can't read you
The server only forwards encrypted data. Even if the infrastructure is seized, there's nothing readable to hand over.
End-to-end encryption
Messages, calls, and files are encrypted with the Double Ratchet and Noise protocols. Keys stay on your device.
Everything you'd expect — privately
A full messenger, designed for untrusted infrastructure.
Encrypted messages
Text, photos, and video, encrypted end to end.
Voice calls
Real-time encrypted calls routed through your chosen relay.
File sharing
Send files up to 25 MB, encrypted per chunk. Delivered even when the other side is offline.
Disappearing messages
Set messages to auto-delete per contact. Nothing lingers longer than you want.
Offline delivery
Messages wait encrypted on the server until your contact reconnects — the server still can't read them.
Built for hostile networks
Domain fronting, multiple relays, and transport fallback keep Phantom working where networks are restricted.
How it works
Three principles that hold Phantom's privacy together.
Your keys stay with you
Encryption keys are generated and stored on your device, protected by your PIN and biometrics.
The server is just a router
Our relays and main server move encrypted packets between devices. They never see plaintext or keys.
Reach only your contacts
Identities are random IDs, not phone numbers. Only people you've added can reach you.
