Just to be clear, this works on App level, not OS, right?
Meaning, this can have different pin codes, each individual to an App?

Yes, that's correct. The PIN code works strictly at the App level. It only locks this specific application and does not affect the device's main OS lock screen. Each app can indeed have its own individual PIN code. Also depend your creation, it's only basic pinlock
