How it works
Three steps from install to an encrypted conversation. Nothing about you leaves your device.
-
1
Join as a Guest
Jump straight in as a Guest. No account, phone number, email, or SIM card required. Generate a private cryptographic identity in seconds.
-
2
Secure discovery
Find contacts via public keys or ephemeral QR codes. Your address book stays private on-device.
-
3
Encrypted connection
Messages and calls are routed through multiple hops, with end-to-end encryption active by default.
The architecture of absolute privacy
Six layers of core infrastructure, built so that no single party — including us — can see who you are or who you talk to.
Sovereign identity
Your identity is a cryptographic key pair known only to you. No central registry, no recovery backdoors.
Quantum-resistant
Future-proof encryption using lattice-based cryptography to protect against quantum computing threats.
Zero-knowledge
We operate the infrastructure but have zero knowledge of your keys, messages, or metadata.
Global node distribution
A decentralized network of thousands of nodes across 140+ countries, ensuring 99.9% uptime.
Self-healing mesh
The protocol automatically reroutes traffic if nodes go offline or network partitions occur.
Protocol deep dive
Silentum isn't just an app; it's a stack. We've layered industry-standard protocols with custom-built metadata stripping layers.
- Layer 1Signal Protocol for messaging
- Layer 2WebRTC + onion routing for voice

Security deep dive
Silentum's architecture ensures that cryptographic keys never leave your device. Our implementation of the Signal Protocol provides the gold standard of messaging security.
-
Perfect forward secrecy
Each session uses a unique key, so a compromised key can't decrypt past communications.
-
Encrypted local storage
All data residing on your mobile device is encrypted with AES-256 at rest.
-
Auto-wipe settings
Set self-destruct timers for messages and use remote wipe if a device is lost.
-
No contact sync permission
We never ask for or upload your address book. You control your network.

Is Silentum free to use?
Silentum offers core communication features and may introduce premium features depending on future business models.
Do I need a phone number or email to sign up?
No. You can join as a Guest in seconds. Silentum generates a private cryptographic identity on your device, with no phone number, email, or SIM card required.
Can Silentum read my messages?
No. Messages are end-to-end encrypted and your keys never leave your device. We operate the infrastructure with zero knowledge of your keys, messages, or metadata.
How do I find and add contacts?
Share your public key or scan an ephemeral QR code. Silentum never asks for permission to read or upload your address book.
What happens if I lose my phone?
Data on your device is encrypted with AES-256 at rest, and auto-wipe settings let you remove messages remotely or on a timer.
Which encryption does Silentum use?
Messaging runs on the Signal Protocol with perfect forward secrecy. Voice uses WebRTC with onion routing, and a custom engine strips metadata. Pro adds a quantum-resistant layer.
Is Silentum available on iPhone?
Silentum is currently available on Android through Google Play.
How do I delete my account?
Follow the steps on our Delete Account page. Because your identity lives on your device, removing it erases your keys permanently.
