About Sryptos

Sryptos is a modern, secure, and anonymous Progressive Web App (PWA) for chat. It's built to showcase advanced web application features while prioritizing user privacy and data ownership above all else.

Core Principles

Sryptos is designed from the ground up with these key features to protect your identity and communications.

Anonymous-First Authentication

Join instantly with just a username. No email or phone number required. Link a Google account later for permanence, if you choose.

End-to-End Encrypted Chat

Using powerful, modern cryptographic libraries (AES-GCM), all your text and files are encrypted on your device by default.

Selectable Encryption Modes

Choose between maximum E2EE security for single-device usage or the convenience of a synced AES-256 mode for multi-device access.

E2EE Voice & Video Calls

Secure, peer-to-peer calls are established directly between users via WebRTC, ensuring your calls remain completely private and confidential.

Progressive Web App (PWA)

Install Sryptos on your desktop or mobile device for a native-app-like experience, including offline access and better performance.

User-Controlled Data

Your data is yours. All chat content is stored on your device, and you have full control over your storage and data permissions.
