How to Send Encrypted Messages Without an App?
Quick Answer
Use zkChat — it runs entirely in your web browser with AES-256-GCM encryption. No app to download, no account to create. Just open the website and go.
Detailed Explanation
Most encrypted messaging requires installing an app: Signal, Telegram, WhatsApp all need downloads and accounts. This creates problems: the app's presence on your device reveals you use it, app stores track downloads, and installation may not be possible on managed devices. zkChat solves this by running entirely in the browser. Open zkchat.org, create a room or one-time message, and communicate with full AES-256-GCM encryption. The Web Crypto API provides browser-native encryption without any third-party code. When you close the tab, there's no app, no history, and no evidence on the device. This makes zkChat ideal for situations where installing privacy apps could raise suspicion.
