+# Happy Server
+
+Minimal backend for open-source end-to-end encrypted Claude Code clients.
+
+## What is Happy?
+
+Happy Server is the synchronization backbone for secure Claude Code clients. It enables multiple devices to share encrypted conversations while maintaining complete privacy - the server never sees your messages, only encrypted blobs it cannot read.
+
+## Features
+
+- 🔐 **Zero Knowledge** - The server stores encrypted data but has no ability to decrypt it
+- 🎯 **Minimal Surface** - Only essential features for secure sync, nothing more  
+- 🕵️ **Privacy First** - No analytics, no tracking, no data mining
+- 📖 **Open Source** - Transparent implementation you can audit and self-host
+- 🔑 **Cryptographic Auth** - No passwords stored, only public key signatures
+- ⚡ **Real-time Sync** - WebSocket-based synchronization across all your devices
+- 📱 **Multi-device** - Seamless session management across phones, tablets, and computers
+- 🔔 **Push Notifications** - Notify when Claude Code finishes tasks or needs permissions (encrypted, we can't see the content)
+- 🌐 **Distributed Ready** - Built to scale horizontally when needed
+
+## How It Works
+
+Your Claude Code clients generate encryption keys locally and use Happy Server as a secure relay. Messages are end-to-end encrypted before leaving your device. The server's job is simple: store encrypted blobs and sync them between your devices in real-time.
+
+## Hosting
+
+**You don't need to self-host!** Our free cloud Happy Server at `happy-api.slopus.com` is just as secure as running your own. Since all data is end-to-end encrypted before it reaches our servers, we literally cannot read your messages even if we wanted to. The encryption happens on your device, and only you have the keys.
+
+That said, Happy Server is open source and self-hostable if you prefer running your own infrastructure. The security model is identical whether you use our servers or your own.
+
+## License
+
+MIT - Use it, modify it, deploy it anywhere.
