WinShell-Bhanu/Clipsync ? reverse-engineered prompt

Build me a simple app that keeps my clipboard in sync between my Mac and my Android phone over the internet.

I want it to feel instant, so when I copy text on one device, it shows up on the other without me having to tap send or open anything extra. Please make it secure too, with encryption before anything leaves the device and decryption on the other side. I’d like a clean, modern interface on both platforms, something that feels native and easy to use.

On Android, it should work quietly in the background and use the needed permissions to detect copy events. On Mac, it should just run smoothly and sync automatically. If you need to look up current docs online while building it, go ahead.

Please set it up so both apps are included in one project and can be run and tested easily.
