Children now grow up with the internet woven into schoolwork, friendships and play, and regulators have decided that the largely hands-off approach of the platform era is over. In country after country, new rules are arriving that restrict how services collect children’s data, what they may recommend to young users, how advertising can target them, and how old someone must be to hold an account at all.
The direction of travel is consistent even where the details differ. Lawmakers cite research on attention, sleep, body image and exploitation, while child development specialists urge care about unintended consequences. Organisations such as UNICEF have long argued that children deserve both protection online and participation in digital life, a balance that new legislation is attempting, imperfectly, to strike.
What the New Rules Require
Most frameworks start with data. Services likely to be used by children must collect as little personal information as possible, switch off profiling and location tracking by default, and avoid design tricks that press children into sharing more or staying longer. Targeted advertising to minors is restricted or banned in several jurisdictions, and recommender systems face duties to avoid pushing harmful material toward young accounts.
Duties of care are the second pillar. Platforms may be required to assess risks to children on their services, act on illegal and harmful content quickly, and provide reporting tools a child can actually use. Age-appropriate design codes translate these ideas into specifics: plain-language privacy notices, default private accounts for teenagers, breaks and prompts around late-night use, and parental controls that are easy to find rather than buried in settings menus.
Age Checks and Their Discontents
Almost every rule depends on knowing who is a child, and that is the hardest problem in the field. Self-declared birth dates are trivially easy to falsify. Document checks work better but create new risks: databases of identity documents are attractive targets for criminals, and adults reasonably object to showing identification to read the news or use a messaging app. Estimation technology, which guesses age from a face or from behaviour, raises its own questions about accuracy and bias.
Critics also warn of exclusion. Children without documents, supportive parents or stable homes may be locked out of services that are genuinely valuable to them, while determined teenagers migrate to less regulated corners of the internet. None of this makes age assurance pointless, but it does mean the technology deserves the same scrutiny as the platforms it polices. A badly designed check can create a privacy problem in the name of solving one.
What Parents Can Do Now
While legislation grinds forward, families are not powerless. The measures with the strongest support are unglamorous: talking regularly about what children encounter online, agreeing shared rules about devices at night, using the privacy and reporting settings that already exist, and keeping accounts private by default. Parents who show curiosity rather than only alarm are more likely to hear about problems early, when they are still small.
Schools and platforms share the remaining work: teaching digital literacy as a basic skill, and designing services that respect young users without constant parental supervision. The tightening of rules worldwide reflects a broad social verdict that children’s data and attention are not simply raw material for business models. Getting the details right will take years of adjustment, argument and evidence, but the underlying principle now commands support well beyond any single country’s politics.
Parents should also remember that no rule replaces conversation. Children who feel comfortable raising problems early are far better protected than those who fear losing their devices if they speak up. Agreements work best when they are mutual: parents explain what worries them, children explain what matters to them, and both revisit the rules as the child grows. Technology, law and parenting each have a role, and none succeeds alone. The tightening of rules is best understood not as an end point but as society catching up with a childhood that has already moved online.
