Progressive Web App

CipherChat on Any Device

Install CipherChat directly to your home screen or desktop. No app store, no tracking, just pure secure communication.

Zero Store Overhead

Install instantly without visiting Google Play or the App Store. No large downloads or update delays.

Enhanced Privacy

PWAs run in a secure sandbox. We don't have access to your contacts, location, or private files.

Full Screen Experience

Removes browser UI for a dedicated, immersive interface that feels like a native system application.

How to Install

PC & Mac (Chrome/Edge/Brave)

Open cipherchat.local in your desktop browser.

Look for the Install Icon (a computer monitor with an arrow) in the right side of the URL address bar.

Click Install. CipherChat will launch in its own dedicated window and add a shortcut to your desktop/launcher.

Alternatively, open the browser menu (three dots) and select "Save and Share" > "Install CipherChat".

The Science of Silence

Progressive Web Apps (PWAs) are a modern standard in application delivery. Unlike traditional apps, they don't require an intermediary (like an App Store) to be installed. This is critical for CipherChat because it ensures that your communication software hasn't been tampered with by third-party reviewers.

Service Workers

These background scripts allow CipherChat to load instantly and manage secure caching of your interface even when network conditions are unstable.

App Manifest

A JSON blueprint that tells your OS how to present CipherChat, defining the splash screens, theme colors, and the secure, borderless window experience.

Secure Context (HTTPS)

PWAs require end-to-end TLS encryption to function, ensuring that the connection between your device and our servers is never intercepted.

Web Crypto API

Because we use standard browser-level encryption (AES-GCM), installing as a PWA ensures your device hardware handles the heavy lifting of security.
