What is the difference between [parental-control] and [children]?

Question

parental-control is self-explaining, from children description:

Programs that are meant to be used when one has children (like adult content blocker etc.)

That is essentially the same.

Answer 1

children covers all software for children and people with children, parental control is only an example. The tag also covers educational software for children (example).

I propose to reserve children for software intended to be used by children, and use parental-control for parental control software, which is intended to be used by parents.
