🔐 Screen Recording Permission

Pin requires Screen Recording permission to function.

On first launch, you'll see the dialog above. Click "Open System Settings" and enable Pin in the Privacy & Security settings.

💡 Why is Screen Recording permission required?

Pin uses macOS's ScreenCaptureKit API to keep windows on top:

1. SCStream captures the target window's content in real-time
2. The captured frames are displayed using AVSampleBufferDisplayLayer
3. This layer is placed in a floating window set to NSWindow.Level.floating

This creates a "mirror window" that stays on top even when the original window is behind other windows. Since ScreenCaptureKit is used to capture window content, macOS requires Screen Recording permission.

🚀 Usage

1. Click the 📌 icon in the menu bar
2. Select "Pin Window..." and choose the window you want to pin
3. To unpin, click the pin icon on the top-left of the mirror window, or select "Unpin" from the menu
