Closing requires proof
Quitting the application stops keyboard and mouse protection: authentication is required before closing is authorized.
Trust centre
Safe Exit
Closing ScreenShield21 requires authentication, and no commercial state should trap a legitimate user.
Leaving must stay possible, and controlled
The password stays available
Whatever the configuration, the password remains the mandatory fallback method.
No commercial lockout
A subscription or licensing state must not, by itself, trap a legitimate user out of their own computer or erase valid recovery methods.
This commitment describes a design intent. It does not guarantee access in every scenario and never bypasses authentication.
