The particular considerations when the user might be a child. Age-appropriate content is the obvious one.

Technical view
Regulatory hooks include children’s data codes requiring high-privacy defaults and age-appropriate design, plus specific provisions in online safety legislation. Practical measures include age assurance proportionate to risk, restricted content and memory settings for minors, crisis escalation routes, and parental transparency. Educational evidence suggests assistance can support or substitute for learning depending on task design, with unstructured use tending towards substitution.
