Why children’s data gets special attention
Children use the same apps, games, video services and school platforms as adults, but they are less able to judge what they are agreeing to. A young child cannot realistically read a long privacy notice, and even teenagers may not foresee how information shared today could be used years later. For this reason, many legal systems and many companies treat data about children differently from data about adults.
There is also a long-term angle. Data collected in childhood can form the start of a lasting digital record. A profile built from early browsing habits, a photo posted by a relative or a school record can follow a person into adulthood unless it is deleted.
What data children generate
Children leave traces in several places:
- Apps and games. Accounts, usernames, in-game chat, purchase history, device identifiers and play patterns.
- Video and social platforms. Watch history, comments, uploaded photos and videos, and recommendations based on viewing.
- Schools and learning tools. Grades, attendance, messages and activity inside learning platforms.
- Connected toys and gadgets. Some toys use microphones, cameras or companion apps, which can capture voice recordings or photos. Wearable technology aimed at children may also track location or activity.
- Family sharing. Parents often post photos or details about their children, sometimes before the child can have any say.
Much of this is collected for ordinary reasons, such as making a game work. Some of it is collected to personalize content or to support advertising, which is where the concern is greatest.
General protections
Rules vary widely, so the following is a general picture and not legal advice.
Age-based consent rules. In the United States, a federal law known as the Children’s Online Privacy Protection Act applies to online services directed at children under 13, or that knowingly collect data from them. It generally requires notice to parents and verifiable parental consent before personal information is collected, with certain exceptions. In the European Union, the GDPR sets an age for a child’s own consent to certain online services. Member states may choose an age between 13 and 16, so the figure differs by country.
Stronger duties on services. Some jurisdictions have introduced codes or rules asking services likely to be used by minors to apply protective defaults, collect less data and avoid features that push children toward oversharing. The scope and enforcement differ from place to place and change over time.
School and education rules. Many countries have separate rules about how schools and education technology providers may handle pupil records.
Platform policies. Apps stores and platforms often set their own requirements for apps aimed at children, such as limits on certain kinds of tracking. How strictly these are applied can vary.
Age limits in terms of service, such as a minimum age of 13 on many social platforms, are commonly self-declared. A child can enter a false birth date, which means the protections that depend on a stated age may not apply to them.
Where gaps remain
Even with laws, gaps appear. Age checks are hard to do reliably without collecting more data. A service that is not designed for children may still be widely used by them. Information posted by parents or friends is often outside the child’s control. And data collected lawfully today can be used later in ways that were not obvious at the time, for example in profiling.
Practical steps for families
No single step is perfect, but these habits help:
- Check app permissions. Many apps ask for access to the camera, microphone, contacts or location when they do not need it. Review and limit these, as discussed in the article on app permissions.
- Use child or teen account settings. Many platforms offer restricted accounts with more private defaults. Look at the options rather than assuming the default is protective.
- Keep accounts private where possible. Choose settings that limit who can see posts or contact the child.
- Be careful with identifying details. Full names, school names, home addresses and live locations are best kept out of public profiles.
- Think before sharing a child’s photos. Consider who can see them and whether the child would be comfortable with them later.
- Talk about it. Explaining why some information is better kept private is often more effective than rules alone. The broader subject of children online and its effects on wellbeing is a separate conversation, but the privacy habits fit into it.
- Look at privacy notices for the services the child uses most. Look for what is collected, whether it is shared and how deletion works.
- Use deletion options. Many services let you close an account or ask for data to be removed, and under some laws parents can request this on behalf of a child.
Looking ahead
Expectations around children’s data keep changing, and new rules appear regularly. A reasonable approach is to treat a child’s data as something to minimize: collect and share only what is needed, and revisit settings as the child grows and gains the ability to make their own choices.
