Frequently asked questions

How's it better than using “Hide app”?: “Hide app” wasn't designed for privacy. For example: if all other apps are hidden, it won't hide the visible app. Boss Key is made for privacy: to hide all apps, mute all sounds, and open a safe app.
Can it hide all apps and websites?: Yep! Boss Key can hide all types of apps and websites, including games, social media, videos, emails, and more. Just make sure the app you're using is not in full-screen mode.
What is full-screen mode?: Full-screen mode is when an app takes up the entire screen, including the menu bar and dock. Most apps that can be run in this mode can also be run in a windowed (non-full-screen) mode too.
What is a “safe app”?: It's an app that runs when you trigger Boss Key. For example, you can get Boss Key to hide the YouTube video your watching and open a spreadsheet app instead, so it looks like you're working.
Does it work across multiple screens?: Yes, Boss Key hides all app windows across multiple screens. So if you extend your MacBook's or iMac's display with an external monitor, Boss Key will hide everything on that screen too.
