Features

• Privacy overlay — blurs or blacks out your screen, with a clear "peek" circle following your mouse
• Three overlay styles — Light Blur, Dark Blur, or Blackout
• Adjustable circle size — from 100px to 1200px diameter
• Smooth tracking — GPU-accelerated mask follows your cursor with zero lag
• Click-through — all mouse clicks pass through to apps underneath
• Multi-monitor support — covers all connected displays
• Menu bar app — no Dock icon, stays out of your way
• Configurable keyboard shortcut — set your own global hotkey in Settings (default: ⌥⌘P)
• Remembers your preferences — circle size, overlay style, and keyboard shortcut persist between sessions

2. Left-click the menu bar icon to toggle the privacy overlay on/off
