Independent, lightweight and reliable chat

Attention: an alpha version of the project is available. Currently, main testing and debugging are conducted on Android, Windows, and in the browser.
Why InterChat
-
Data Saving
Architecture and small details (like the type of emojis or how video is sent/received during a call) - everything is optimized to save internet data and bandwidth.
-
Security
Your account is your fortress. Enhanced authorization and secure access recovery protect your profile from intruders. Thanks to built-in protection algorithms, your data leaves the device ONLY in encrypted form.
-
Bank-level privacy
Your correspondence is hidden from prying eyes and protected by advanced algorithms. We do not transfer data to advertisers and work in strict compliance with information security legislation.
-
Lightweight
A small, optimizied app that tries to do with minimal third-party libraries and dependencies, resulting in a smaller download size.
-
Speed
Optimization of everything possible - from architecture to the user client.
-
Calls and video connection
Communicate by voice and video in real time.
Important: When starting for the first time, Windows Defender may show a warning about an unknown application.
This is normal: we are independent developers, and while InterChat is in its alpha version, we have not yet issued an expensive digital certificate.

Chat for business and people
InterChat is a secure chat app for personal and corporate communication.
Whilst developing it our 2 primary goals were to
1. Save bandwidth and work in poor internet connections
2. Security
There are only two of us, and we have no third-party investors. Our goal is to create a reliable messenger, resistant to blocking, where your data belongs only to you. InterChat is equally reliable for everyday chats with loved ones as it is for protecting companies' confidential business processes.
We use advanced encryption algorithms. Brute-forcing them is mathematically impossible — decrypting the data would take hundreds of years of calculations. Even if traffic is intercepted, stolen files will be absolutely useless to attackers.
Not only are your text messages protected, but also all transferred media files, archives, and corporate documents. Users' emails and phone numbers are never stored in plain text on our servers.
No data collection. We do not analyze your internet connection, we do not download your phone book, and we do not track which programs you are working with.
Dynamic group protection: As soon as an employee or member leaves a chat group, the system instantly updates the encryption keys, permanently blocking their access to future correspondence and new files.
We use only proven tools: a native Kotlin client and a high-performance Go backend. Start a secure dialogue on your smartphone and continue it on your work computer — the messenger is already available for Android and Windows. Builds for Linux and iOS (iPhone) are already being prepared for release and will be available soon.
