What parental controls can and cannot do
Parental controls are filters and limits: they block categories of websites, restrict app installs, cap screen time, and report usage. They are good at removing the obvious and the accidental. They are far weaker against the things that actually hurt children, because harm usually arrives inside apps a family has already approved — a direct message in a game, a comment under a video, a group chat with classmates.
- Strong at: blocking adult sites, limiting purchases, enforcing bedtime, restricting app installs.
- Weak at: grooming inside approved apps, bullying in group chats, scams sent by a friend's hacked account, self-harm content shared privately.
- Blind by design: encrypted messaging, disappearing content, and anything on a friend's device.
