Your software sounds like malware. If I came across it I would probably make a YARA rule against it to purge it from any managed network I control.
Anyway, the "head of the household" should get out of 1920 and find out about talking to your family like a person and using standard parental controls as validation, not weird policing. If you make your home a battle, people will find the stuff they want elsewhere and not talk to you about it if they have questions.
