How is my privacy protected?
ShutterMinder never records, saves, or transmits video. It performs a brief in-memory shutter check on your Mac and keeps the result local.
Why does it need camera permission?
macOS requires camera access so the app can run a local hardware verification of your physical shutter state. All checks happen in-memory and instantly.
Will it work with my external webcam?
Yes. It is built for MacBook cameras, external webcams, and desk setups that use more than one camera.
Is there a cloud service behind it?
No. The app works on your Mac without any cloud account or sync service to keep your data safe.
