NoPeek

什么是 NoPeek？

Ever caught someone reading your Mac over your shoulder at a cafe, on a flight, or in a coworking space? NoPeek lives in your menubar and uses your front camera + Apple's Vision framework to spot a second face in frame. When it does, your screen instantly blurs, dims, locks, or keeps only a Focus Zone around your cursor so you can keep working. Walk away? It protects itself until you're back. 100% on-device, no cloud, no account. $9.99 unlocks everything. Free version available on the GumRoad.
