Choose apps to lock and ctrlhq keeps them hidden until you unlock them with Touch ID or your Mac password. Once you've been away from an app for a while, it locks again.

Questions
Can notifications from a locked app still show up?
Yes. App Lock hides the app's windows, not macOS notifications, so a banner can show its text. To hide that, set the app's notification previews to Never in System Settings → Notifications.
Is this full security?
It's a privacy screen for shared or presented Macs, not a replacement for a separate user account.
