+## 🚧 Project Update: Transition to Desktop & Mobile Versions
+
+The **web version of SecureBit.chat** will remain available and stable,  
+but **no major updates** are planned in the near future.
+
+We are now focusing on developing **next-generation desktop and mobile applications** powered by **Tauri v2**,  
+bringing new features that will be **fully backward-compatible** with the current web version:
+
+- **Offline communication** via LoRa & mesh networking  
+- **Improved encryption performance** with native crypto modules  
+- **Cross-platform synchronization** between devices  
+- **Local secure storage & hardware key integration**
+
+These new builds will enable true **serverless communication** even under restricted or offline conditions.
+
+If you appreciate our mission to build **decentralized, censorship-resistant communication**,  
+please **support the project by starring it on GitHub** — your support helps development and visibility!
