Communication, made familiar
An everyday messenger.
A considered approach to privacy.
No new way of chatting to learn. Keep the complexity in the encryption, and the conversation where it belongs.
01 / 03
Even a simple hello deserves protection.
Clear conversations and familiar message bubbles. Share text, photos, voice messages and files in one natural flow.
02 / 03
More ways to say what matters.
Hold to record, choose a photo or send a file. Attachments download and decrypt when opened. Save them to a location you choose.
03 / 03
Give messages the right amount of time.
Set retention for new messages, or choose a local timer after viewing. Manage the timeline on your current device with clear controls.
Illustrative interface previews. Each platform uses native controls; final screens may differ in the approved test release.
Security starts at the endpoints
Carry the message.
Protect the conversation.
Built on Matrix end-to-end encryption. Messages and attachments encrypt and decrypt on the clients, while the server carries ciphertext.
Privacy controls you can see
Encryption status and retention settings sit inside the conversation, with important choices close at hand.

Device identity verification is still in development. Encryption does not hide all communication metadata. Use test content in this preview.
Infrastructure on your terms
Your server.
Your space to communicate.
One client, different deployments. Run the backend on your LAN or in your own cloud, and choose where your communication infrastructure lives.
Connect across the distance.
A trusted HTTPS endpoint connects your cloud deployment to test devices in different locations.
Keep the infrastructure in your network.
Run the backend on your LAN with HTTPS trusted by the clients. Phone registration needs an online SMS service; administrators can create LianChat IDs.
Self-hosted serverHTTPS
One client. Your server address.

Conversations have their own rhythm
A moment, on your terms.
Choose how long new messages stay on the local timeline. Keep local visibility, explicit exports and server retention policies distinct.
Local clearing does not erase copies on the peer, server or exported files. Cross-device timers and per-message remote destruction are still in development.

A few things before you begin
Can one client connect to different servers?+
Yes. The welcome screen keeps a manual server API address setting. Use the same client with different cloud or LAN deployments, without rebuilding it for each server.
What can I share today?+
The current preview supports end-to-end encrypted text, photos, voice messages and files in one-to-one chats, with a 20MB attachment limit. Live calls and platform push are in development.
Does local clearing erase every copy?+
No. Current timers affect the local timeline and its previews. They do not guarantee erasure on peer devices, servers, runtime copies, system backups or exported files. Cross-device timers and per-message remote destruction are not implemented yet.
How do I get started?+
Downloads will open after release approval. Install the build supported by your platform and signing profile, then enter your server on the welcome screen. A bare host such as im.lianchat.app defaults to HTTPS. Registration uses an account name, an SMS code and password confirmation.
