Join the independent project
Chat for business and people
InterChat is a secure domestic platform for personal and corporate communication.
There are only two of us—an independent team of developers with no outside investors or corporate constraints. Our goal is to create a reliable messaging platform resilient to external blocks, where your data belongs exclusively to you. InterChat is equally dependable for everyday conversations with loved ones and for safeguarding confidential corporate workflows.
Security and Privacy by Default
Robust End-to-End Encryption: We rely on modern cryptographic algorithms. Brute-forcing them is mathematically impossible—decrypting the data would take hundreds of years of computation. Even if traffic is intercepted, your data remains completely inaccessible to attackers.
Full File Protection: We secure not just text messages, but also media files, archives, and corporate documents. User email addresses and phone numbers are never stored on our servers in plain text.
Zero Data Collection: We do not analyze your internet connection, upload your contacts, or monitor the applications you use.
Dynamic Group Security: As soon as an employee or participant leaves a group chat, the system immediately rotates the encryption keys, revoking their access to future messages and incoming files.
Availability Across All Devices
We build with proven, lightweight technologies: native clients powered by Kotlin Multiplatform and a high-performance backend written in Go. Start a conversation on your smartphone and pick it right back up on your work computer:
Mobile Devices: Available on Google Play (for Android) and the App Store (for iPhone and iPad).
Desktops and Laptops: Dedicated clients for Windows, macOS (Apple Mac), and Linux can be downloaded directly from our website.
