What Parents Need to Know About Children’s Data

Today’s children are growing up in a world that collects data from the moment they touch a screen, and sometimes even before. From baby monitors and smart toys to school apps and social media, technology companies gather, analyse, and store children’s personal information in ways most adults never experienced growing up.

And yet, many parents still feel unsure about what’s being collected, who sees it, and how to protect their children’s digital footprints.

If you’ve ever wondered:

“What data is my child actually sharing?”
“How do apps and platforms use children’s information?”
“What are my child’s privacy rights?”
“How can I keep my child safe without banning everything?

Then this guide is for you.

What You Need to Know

Children generate more data than ever through apps, games, schools, devices, and even family posts, and that data can shape their opportunities, safety, and future. Protecting children’s privacy isn’t about fear; it’s about simple habits that give them more control and help them grow up confident in a digital world designed to track them.

Children’s data is uniquely sensitive, long‑lasting, and heavily targeted by companies.
Apps, games, schools, smart toys, websites, and home devices collect data everywhere.
Companies use this data to personalise content, target ads, predict behaviour, and build profiles.
The risks include manipulation, oversharing, breaches, identity theft, and long‑term tracking.
Children have strong legal rights: to understand, access, delete, correct, and limit their data.
Parents can make a big difference with simple habits like privacy checks, location controls, and open conversations.

Why Children’s Data Needs Extra Protection

Children aren’t just “small adults.” Their data is more sensitive, more valuable, and far more vulnerable — and the digital world treats it differently for good reason. When a child goes online, every tap, swipe, search, and sign‑up can create a trail of information they don’t fully understand and can’t easily undo. That’s why children’s data needs stronger safeguards, clearer rules, and more mindful handling from the adults and companies around them.

Here’s what makes children’s data uniquely important to protect.

1. Children can’t fully understand what they’re sharing

Kids lack the life experience to understand how data moves, how long it lasts, or how people can use it.

They might share personal details, photos, or preferences without realising:

Who can see it
How it might be stored
How it could be used to target them later

Their decisions are impulsive and present‑focused. Not because they’re careless, but because they’re still developing the ability to think long‑term.

2. Their data lasts a lifetime

A child can’t “start fresh” at 18. Anything collected about them — accounts, posts, search history, behavioural data, can follow them into adulthood.

That means:

Early mistakes can linger
Old accounts can become security risks
Childhood interests can shape future profiling

A digital footprint created at age 7 shouldn’t define someone at age 27.

3. Children are easier to influence

Algorithms don’t just show content, they shape it. And children are especially impressionable.

They’re more likely to:

Internalise what they see
Compare themselves to others
Believe content is “popular” rather than “algorithmically boosted”
Follow recommendations without questioning them

This makes targeted content, extreme videos, and persuasive design far more powerful and potentially harmful.

4. Children are prime targets for scammers

Kids are naturally trusting, curious, and eager to explore. That combination makes them ideal targets for:

Fake giveaways
Phishing attempts
Impersonation scams
Manipulative in‑game purchases

They’re less likely to spot red flags and more likely to click without thinking.

5. Children’s data is legally protected

Laws recognise that children need extra safeguards.

In the UK, frameworks like the UK GDPR and the Age‑Appropriate Design Code require companies to:

Minimise data collection
Avoid manipulative design
Offer high privacy settings by default
Explain things in child‑friendly language
Treat children’s data as high‑risk

These protections exist because children cannot meaningfully consent in the same way adults can.

6. Companies see children as future customers

Children represent long‑term commercial value.

Data collected today can influence:

Future advertising
Brand loyalty
Behavioural profiling
Purchasing habits

This creates powerful incentives for companies to gather as much information as possible unless strict rules stop them. Children’s data isn’t just sensitive; it’s powerful. It can shape their identity, their opportunities, and their future digital experiences. That’s why it deserves careful handling, thoughtful boundaries, and powerful protection from the adults and systems around them.

What Counts as “Children’s Data”? (More Than You Think)

Most parents think of children’s data as the obvious things — names, photos, birthdays, school details.

But in reality, children generate far more data than adults often realise. Modern apps, games, devices, and platforms collect information constantly, often in the background, and often without a child understanding what’s happening.

Children’s data includes anything that can identify them, describe them, track them, or build a picture of who they are and how they behave.

Here’s what that really covers.

Personal information

The basics, but still highly sensitive.

Full name
Age and date of birth
Home address
School or nursery
Medical details
Family information (parents’ names, siblings, household setup)

This is the data most parents expect, but it’s only the starting point.

Digital behaviour

Every tap, scroll, and search creates a behavioural trail.

Browsing history
Search terms
Watch history on YouTube or streaming apps
App usage patterns
Gaming habits and in‑game behaviour

This data reveals interests, routines, and even personality traits.

Location data

One of the most sensitive categories and often collected automatically.

GPS tracking from phones and wearables
Check‑ins
Geotagged photos
Nearby Wi‑Fi networks and Bluetooth devices
Location data can show where a child lives, goes to school, plays, and spends time.

Biometric data

Increasingly common as devices become more advanced.

Fingerprints used to unlock phones or tablets
Facial recognition in photos or login systems
Voice recordings from smart speakers or voice notes

Biometrics are permanent because you can’t change your face or fingerprints.

Educational data

Schools and learning platforms collect huge amounts of information.

Homework submissions
Behaviour logs
Assessment results
Attendance records
Learning patterns and progress data

This can reveal academic strengths, struggles, and personal development.

Social data

Everything that shows how a child interacts with others.

Friends lists
Messages
Comments
Likes and reactions
Group chats
Shared photos or videos

This data maps a child’s social world and relationships.

Device data

Technical information that identifies the device and therefore the child using it.

IP address
Device model
Operating system
Unique device identifiers
App permissions

This data is often used for tracking, profiling, and targeted advertising.

Emotional and behavioural signals

Subtle but powerful and heavily used by algorithms.

What they pause on
What they rewatch
what they click
What they skip
What they avoid
How long they stay on a screen

These signals help platforms predict mood, preferences, and vulnerabilities.

Children generate thousands of data points every week, often without realising it and without the ability to understand what it means. That’s why children’s data needs stronger protection, clearer rules, and more mindful oversight from the adults around them.

Where Children’s Data Gets Collected

Children’s data doesn’t just come from social media. It’s gathered across almost every part of their digital lives — often quietly, automatically, and in ways parents don’t always see. Modern technology collects information in the background, and children interact with far more connected systems than previous generations ever did.

Here’s where children’s data is most commonly collected.

1. Apps and games

Many free apps rely on data collection to make money, especially through advertising and in‑app analytics.

They often gather:

Device information

Gameplay behaviour

In‑app purchases

Location data

Advertising identifiers

Even simple games can contain multiple trackers running behind the scenes.

2. Social media platforms

Even if your child is “too young,” they may still have accounts or appear in other people’s posts.

Platforms collect:

Likes, comments, and shares
Viewing habits
Friend networks
Facial recognition data
Private messages

And even “kid‑friendly” versions of apps still gather behavioural data to personalise content.

3. School platforms

Education technology is now part of everyday learning, and it collects far more than homework.

This can include:

Login details
Attendance
Behaviour logs
Assessment results
Learning patterns
Communication with teachers

Schools must follow strict rules, but the volume of data is still significant.

4. Smart toys and devices

Connected toys and home devices can collect data without a child ever typing a word.

Examples include:

Talking dolls that record audio
Smart speakers that store voice commands
Fitness trackers that log steps and sleep
Tablets that track usage and app activity

These devices often send data back to manufacturers or cloud services.

5. Streaming services

Platforms like YouTube, Netflix, Disney+, and TikTok gather detailed information about what children watch and how they interact.

They track:

Watch history
Replays and pauses
Search terms
Recommended content clicked
Time spent watching

This data feeds algorithms that shape what children see next.

6. Websites

Even simple websites collect data through cookies, trackers, and analytics tools.

This can include:

Browsing behaviour
IP address
Device type
Location estimates
Interaction patterns

Many sites run dozens of trackers, even on pages aimed at children.

7. Family devices

Children often use shared devices, and those devices collect data too.

Examples:

Your phone or tablet
Your smart TV
Home assistants like Alexa or Google Home
Shared laptops

These devices may store voice recordings, app activity, and search history linked to your household.

8. Photos and videos

Children appear in photos and videos shared by:

Parents
Relatives
Friends
Schools
Clubs and activities

Once shared, these images can be analysed for facial recognition, location, and context, even if posted privately.

Companies collect children’s data everywhere — across apps, devices, schools, entertainment, and even family routines. Much of it happens automatically, and often in places parents don’t expect. Understanding where data comes from is the first step in protecting it.

How Companies Use Children’s Data

Companies don’t collect children’s data “just because.” Every piece of information serves a purpose — some of those purposes are harmless and genuinely useful, while others raise genuine concerns about influence, profiling, and long‑term tracking. Understanding why companies want this data helps parents see the bigger picture behind the apps, games, and platforms their children use.

Here’s how children’s data is typically used.

1. Personalisation

Platforms use data to tailor what a child sees.

2. Advertising

Even when advertisers call ads “child‑friendly,” they can still target them based on behaviour.

Companies may use:

Viewing habits
Interests
Device data
In‑app activity

This allows advertisers to reach children with products they’re more likely to click on or ask for.

3. Behaviour prediction

Platforms analyse what keeps children watching, playing, or scrolling.

They look at:

What they pause on
What they rewatch
How quickly they scroll
Which characters or themes they prefer

This helps companies predict what will hold a child’s attention and design content that keeps them engaged.

4. Product development

Data helps companies improve features and build new ones.

For example:

Which levels do children get stuck on
Which tools do they use most in learning apps
Which features they ignore
How long they spend on certain tasks

This can lead to better products, but it also means children are effectively unpaid testers.

5. Profiling

Over time, companies build a long‑term picture of a child’s preferences and habits.

Profiles can include:

Interests
Personality traits
Learning style
Social behaviour
Emotional responses

These profiles can follow a child across devices and into adulthood.

6. Data sharing

Some companies pass information to third parties — sometimes legally, sometimes in ways that push the boundaries.

This may include:

Advertisers
Analytics companies
Cloud services
partner apps
Data brokers (in some regions)

Even when personal data isn’t shared directly, insights about behaviour often are.

7. Engagement optimisation

Platforms use data to design experiences that keep children online longer.

This can involve:

Autoplay
Infinite scroll
Streaks and rewards
Push notifications
“Just one more” game mechanics

These features are built using behavioural data to maximise time spent on the platform.

8. Monetisation

Companies don’t always sell personal data, but they often sell insights.

For example:

“Children aged 7–9 love this type of content”
“Kids who watch X are more likely to buy Y”
“This game mechanic increases engagement by 40%”
These insights are valuable to advertisers, investors, and product teams.

Children’s data is valuable, and companies know it. The more they understand about how children think, behave, and react, the more they can shape products, advertising, and experiences around them. That’s why children’s data needs careful handling, strong protections, and informed oversight from parents.

The Risks of Children’s Data Being Collected

Not all data collection is harmful. Some of it is necessary for learning platforms, safety tools, or basic app functionality. However, the widespread and often invisible gathering of children’s data creates risks that parents deserve to understand. These risks aren’t about panic; they’re about awareness, boundaries, and informed choices.

Here are the key concerns.

1. Over sharing and exposure

Children often share personal details without realising the consequences.

This can include:

Their full name
Their school
Their location
Photos of themselves or their homes
Personal interests or routines

Once shared, this information can spread far beyond the original app or audience.

2. Targeted advertising

Even “child‑friendly” ads can shape how children see themselves and what they think they need.

Risks include:

Pressure to buy certain products
Unrealistic body image expectations
Feeling left out if they don’t have what others do
Subtle nudges toward certain brands or behaviours

Children are more impressionable, so targeted ads hit harder.

3. Manipulation through algorithms

Algorithms don’t just show content — they influence what children think, feel, and believe.

They can push:

Extreme trends
Unhealthy challenges
Beauty filters
Diet culture
Intense fandoms
Content that encourages comparison or insecurity

Children may not realise they’re being steered in a particular direction.

4. Data breaches

If hackers breach a company, they can leak children’s data, and recovering leaked data is almost impossible.

This can expose:

Personal details
Photos
School information
Behavioural data
Login credentials

Children can’t control where this information ends up.

5. Identity theft

Children’s clean credit histories are extremely valuable to criminals.

Stolen data can be used to:

Open bank accounts
Apply for loans
Create fake identities
Commit fraud

Most families don’t discover the problem until years later.

6. Long‑term profiling

Data collected in childhood can shape how companies treat them in the future.

This might influence:

What content they’re shown
What ads they receive
How they’re categorised as consumers
What opportunities or recommendations they see
A profile built at age 8 shouldn’t define someone at age 18, but it often does.

7. Loss of privacy

Children growing up today may never experience a truly private life.

Constant tracking means:

They monitor their habits
They record their preferences
They analyse their behaviour
Their digital footprint grows before they understand it

Privacy becomes something they never had, rather than something they lost.

8. Safety risks

When personal details fall into the wrong hands, the risks become real.

This includes:

Location data revealing where a child lives or goes to school
Photos that can be misused or re-shared
Personal details that make grooming or impersonation easier
Combining even small pieces of data creates a detailed picture of a child’s life.

Children deserve a childhood that isn’t quietly tracked, analysed, and monetised. Understanding the risks doesn’t mean avoiding technology — it means using it wisely, setting boundaries, and making sure children grow up with safety and dignity at the centre of their digital lives.

Children’s Privacy Rights

Children have some of the strongest privacy protections in the world — especially in the UK and EU, where the law recognises that children are more vulnerable, less informed, and more easily influenced. These rights exist to ensure children can explore, learn, and play online without being exploited, tracked, or manipulated.

1. We must treat children’s data with extra care

Companies must collect the minimum amount of data needed to provide a service. No unnecessary tracking, no “just in case” data gathering, no hidden extras. This principle is at the heart of the UK GDPR and the Age‑Appropriate Design Code.

2. Children must be able to understand what’s happening

You must write privacy information in clear, child-friendly language — not legal jargon.

That means:

Simple explanations
Visual cues
Age‑appropriate examples
No confusing or misleading wording

If a child can’t understand it, the company hasn’t met its legal duty.

3. Children’s data cannot be used in manipulative ways

Companies must avoid:

Dark patterns
Nudges
Pressure tactics
Design tricks that push children to share more data

No one should manipulate children into surrendering their privacy.

4. Children may access their data

A child, or their parent acting on their behalf, can ask any company:

What data they hold
How they got it
What they’re doing with it
Who they’ve shared it with

And the company must provide it.

5. Children may delete their data

Children (and parents) can request deletion, especially when:

Data collected when they were younger
An account is no longer used
Content is embarrassing or outdated
The child didn’t understand what they were agreeing to

This is sometimes called the “right to be forgotten.”

6. Children may have inaccurate data corrected

If a school, app, or platform holds incorrect information, they must fix it.

This includes:

Wrong grades
Incorrect behaviour notes
Outdated personal details
Mislabelled accounts

Accuracy is a legal requirement.

7. Children have the right to privacy from profiling

Companies must limit behavioural tracking and cannot use profiling to:

Target children with ads
Shape their behaviour
Influence their decisions
Predict their vulnerabilities

Profiling children is high‑risk and heavily restricted.

8. Children have the right to safety by design

Developers must build apps and platforms with children’s well-being in mind from the start.

This includes:

High privacy settings by default
Safe search options
Limits on data sharing
Protections against harmful content

Safety cannot be an optional extra.

9. Children may switch off location tracking

Location tracking must be off by default for children.

If it’s on, it must be:

Clearly explained
Easy to turn off
Used only when absolutely necessary

Location data is one of the most sensitive forms of personal information.

10. Children may have age‑appropriate experiences

Children should not be exposed to:

Adult content
Adult‑level data collection
Adult‑focused features
Unsafe or unsuitable communities

Platforms must tailor experiences to a child’s developmental stage.

These rights exist to protect children from exploitation, manipulation, and long‑term harm. They ensure children can grow up with dignity, safety, and autonomy, and that companies treat their data with the seriousness it deserves.

What Parents Can Do to Protect Their Child’s Data

Protecting your child’s data doesn’t require specialist knowledge or advanced tech skills — it starts with small, everyday habits that build up. Children move through a digital world that collects information constantly, often without them realising it, and parents play a crucial role in shaping how they navigate that world. With a few simple routines, you can give your child more privacy, more safety, and more confidence online.

1. Review privacy settings together

Sit with your child and go through their apps, games, and accounts side by side. This turns privacy into a shared routine rather than a lecture.

Check:

Who can see their posts
Who can message them
What data the app collects
whether location is on
Whether their profile is public or private
What permissions the app has (camera, microphone, contacts, photos)

Doing this together helps children understand why settings matter and builds confidence in managing their own privacy.

2. Turn off location tracking

For children, location data is one of the biggest risks, and most apps don’t need it.

Turn off:

Real‑time location
Location tagging in photos
Location history
“Nearby friends,” features
Background location access

If an app genuinely needs location (e.g., maps), turn it on only when using it.

3. Use child‑friendly versions of apps

Platforms like YouTube Kids, supervised accounts, and age‑appropriate modes offer:

Safer defaults
Limited data collection
stronger content filters
Fewer ads
Clearer parental controls

The designers created these versions with children’s rights and safety in mind.

4. Teach children the “three questions” rule

Before posting or sharing anything, encourage your child to pause and ask:

Is it true?
Is it kind?
Is it safe?

This simple habit builds digital judgement, reduces oversharing, and helps children think before they tap.

5. Avoid posting identifying details

Minor details add up and can reveal more than you expect.

Be cautious with:

School uniforms
Street signs
House numbers
Birthdays
Full names
Daily routines
Photos taken outside your home

If you share family photos, consider cropping backgrounds or using close‑ups.

6. Use strong passwords and 2FA

Children’s accounts get hacked too, especially gaming accounts, which often hold valuable items or payment details.

Use:

Long, unique passwords
A password manager (family‑friendly ones exist)
Two‑factor authentication (text, app, or hardware key)

This protects both your child’s data and your family’s devices.

7. Talk openly about scams

Make scam‑spotting a normal part of digital life. Children should feel comfortable asking for help without fear of getting into trouble.

Teach them to watch for:

Fake friend requests
Phishing messages
“Free Robux/V‑Bucks,” offers
Suspicious links
Requests for personal info
Pressure to act quickly

Reassure them that pausing and checking is always the right choice.

8. Check school apps and platforms

Schools often use third‑party tools for homework, communication, and behaviour tracking.

You can (and should) ask:

What data is collected?
Who has access to it?
How long is it stored?
Is it shared with anyone?
What happens if we want it deleted?

Schools must be transparent, and you’re entitled to clear answers.

9. Limit smart toys and devices

Some smart toys collect far more data than parents realise.

They may record:

Voice
Location
Conversations
Usage patterns
Sleep or movement data

Choose toys that don’t connect to the internet unless absolutely necessary and turn off features you don’t use.

10. Model healthy digital behaviour

Children copy what they see, and your habits will become their habits.

If you:

Over share
Post everything
Leave location on
Accept every permission
Never check privacy settings

Then your child will learn to do the same.

Show them what thoughtful, balanced digital behaviour looks like, and they’ll follow your lead.

How to Talk to Children About Their Data (Without Scaring Them)

Talking about data shouldn’t feel scary or technical. When you keep the tone calm, curious, and collaborative, children learn that privacy is simply part of being confident and capable online.

1. Use simple language

Kids don’t need jargon, they need metaphors they can picture.

“Your data is like your backpack. You don’t hand it to strangers, and you choose what you keep inside.”

Simple comparisons help them understand that data is theirs, and they have a right to protect it.

2. Focus on safety, not danger

Fear shuts down learning. Safety opens it up.

Instead of “Bad people might steal your information,” try:

“These settings help keep you safe online, just like wearing a seatbelt keeps you safe in the car.”

The message becomes: You’re capable, and we’re preparing you, not scaring you.

3. Encourage questions

Children learn best when they feel free to explore ideas.

Ask open questions like:

“What do you think this app knows about you?”

“Why do you think it asks for your birthday?”

“What would you choose to share?”

This turns privacy into a conversation, not a lecture.

4. Make it a team effort

Kids feel more confident when they know adults are learning too.

“We’re figuring this out together. Even grown‑ups have to check their settings.”

This removes pressure and shows them that privacy isn’t about perfection, it’s about paying attention.

5. Avoid shame

If they overshare or click something they shouldn’t, stay calm.

“It’s okay, everyone makes mistakes online. Let’s look at what happened and fix it together.”

Shame shuts down honesty. Calm curiosity keeps them coming back to you when something feels wrong.

6. Explain why companies collect data

Kids are smart. They want to know why things happen.

“Apps collect information to show you videos you like, but we get to choose what we share.”

This helps them understand the trade‑off: convenience vs. privacy. It also teaches them that they have agency, even in digital spaces designed to pull them in.

7. Keep the conversation ongoing

Privacy isn’t a one‑time talk, it’s a life skill that grows with them.

Bring it up naturally:

When downloading a new game
When a website asks for permission
When they get a new device
When they start using social features

Short, regular conversations build confidence far more effectively than one big “privacy talk.”

The Future of Children’s Data (And Why It Matters Now)

Children today are growing up in a world where data isn’t just a by‑product of life — it shapes life. The information they generate now will influence the opportunities they see, the choices available to them, and even how they’re understood by the systems around them. This isn’t science fiction; it’s the direction society is already moving in.

Children will grow up in a world where:

Algorithms shape opportunities, from what they learn to what they’re recommended
Digital footprints influence decisions, from school admissions to job screening
Data is used in education, healthcare, and employment, often automatically, behind the scenes
Online identity becomes part of real identity, merging who they are offline with who they appear to be online

Therefore the habits children build now matter so much. The way they share, protect, and understand their data will echo into adulthood, affecting everything from their privacy to their confidence to their future choices.

Teaching children about data isn’t about fear or restriction.

It’s about equipping them with the tools, awareness, and judgement they’ll need to navigate a data‑driven world with confidence. It’s about helping them grow into adults who understand their rights, value their privacy, and feel empowered, not overwhelmed, by technology.

If You Only Remember One Thing…

Your child’s data shapes their future. Protecting it today protects their choices, their confidence, and the person they’ll grow into tomorrow, giving them the freedom to explore, learn, and thrive without being quietly tracked or defined by their digital past.

What to Remember

Children are growing up in a world that constantly collects their data. Often quietly, automatically, and long before they understand what it means. Protecting their privacy isn’t about fear or perfection; it’s about small, steady habits that give them more safety, more control, and more confidence as they explore the digital world. Understanding how children’s data is collected, used, and protected empowers parents to make choices that genuinely shape their child’s future.

Here are the key things to keep in mind:

Children’s data is more sensitive, more valuable, and more vulnerable than adults often realise.
Data comes from everywhere, including apps, games, schools, devices, toys, websites, and even family posts.
Companies use children’s data to personalise content, predict behaviour, target ads, and build long‑term profiles.
The risks include over sharing, manipulation, data breaches, identity theft, and long‑term tracking.
Children possess significant legal rights that permit them to understand, get, remove, change, and control how others use their information.
Privacy settings, location controls, and safer app versions make a huge difference.
Teaching children simple habits — like thinking before posting — builds lifelong digital judgement.
Parents can ask schools and companies about their methods for collecting, storing, and sharing data.
Your own digital habits set the tone; children learn privacy by watching what adults do.
