Secure Messaging App:
Private Chat without central servers
Secure messaging with end-to-end encryption based on Signal Protocol. You choose the server. You control the metadata.
WhatsApp depends on Meta. Telegram doesn't encrypt everything. Signal is centralized. TilliT is decentralized: each server is independent, messages stay yours.
No third-party cloud. No mandatory phone number for private servers. Private chat for family, teams, businesses.
What is TilliT and how it works
Unlike traditional apps, TilliT is designed for decentralization: you choose the server you trust with your connection.
Even when switching servers, protection remains: message content is covered by end‑to‑end encryption.
Result: more control over infrastructure and context, without sacrificing content security.

End-to-End Encryption with Signal Protocol
End‑to‑end encryption protects messages: the server transports but cannot read.
Chat Security: Real End-to-End Encryption
Every message in TilliT is protected with Signal Protocol, a recognized standard for secure messaging.
This means the server transports but cannot read the content of conversations.
Simple model: transport ≠reading
The server is a routing point, not a trust point for content: confidentiality is guaranteed end‑to‑end.
Signal Protocol for Encrypted Messages
Only participants' devices can decrypt messages: end‑to‑end means the content stays between you.
Private cryptographic keys remain on the device with native protected storage: iOS Keychain and Android Keystore.
Private Keys on iOS and Android Devices
Real-time chat, message replies, image and file sharing, audio, video, and location messages.
All protected by the same end‑to‑end encryption.
Private rooms with invitations
Create rooms and invite through unique codes. Controlled sharing and simple onboarding.
Automatic cryptographic sessions
When a new participant joins, TilliT automatically establishes secure sessions to protect from the first message.
Delivery statuses
Clear indicators: sending, sent, received, delivered, read. Useful without invading privacy.
Private Chat for Businesses, Teams, and Families
TilliT is for those who want to communicate simply, but with real control over their infrastructure.
It's a suitable choice when privacy isn't "an option" but a requirement.
Family Chat Without Tracking
A server managed by someone you trust, to stay in touch without going through platforms that monetize data.
Secure Messaging for Businesses
Internal communications under control: you can choose where metadata resides and who administers the infrastructure.
Private Server for Communities
An independent and self-managed space, with invitations and private rooms. The network grows by adding servers, not by centralization.
Get Started: choose your server
You can use an existing server (for example the official one) or rely on a trusted server managed by a person or group you know.
If you want maximum control, you can also create your own private server.
