How it works
Open it
Launch Karas in your browser or install the app.
Create an account
In a couple of seconds, with no phone number required.
Chat securely
Private chats are encrypted automatically.
We do not read your messages. And we can’t.
Encryption keys are stored only on your device. The server sees nothing but an encrypted string of characters. That means no one — not the provider, not an attacker, not the service owner — can access the content of your private chats.
