For today's children, the online world is often just as familiar as the offline one. They use educational websites, chat with friends, play online games, watch videos and explore social media from a young age. While these digital experiences can be fun and beneficial, they also require an understanding of online safety.
Many children do not realise that information shared online can sometimes be viewed, copied or misused by people they have never met. Something that seems harmless to a child may provide enough information for someone else to identify them, locate them or gain access to personal details.
Teaching children what information should remain private is one of the most effective ways to help keep them safe online. These conversations should begin early and evolve as children grow and use more digital platforms.
Why Online Privacy Matters
Children often view the internet as a place to connect, learn and have fun. They may not fully understand that information shared online can remain there for years or reach people far beyond their intended audience.
Protecting personal information helps reduce risks such as identity theft, scams, cyberbullying, unwanted contact and privacy breaches. It also teaches children to think carefully before sharing information in any online environment.
Developing strong privacy habits early can help children make safer decisions throughout their lives.
Full Name
While first names are often acceptable in certain settings, children should avoid sharing their full names publicly unless a parent or trusted adult has approved it.
A full name can be used alongside other information to identify a child, locate social media profiles or gather additional personal details.
Parents can explain that not everyone online needs to know exactly who they are.
Home Address
A child's home address should never be shared online.
This includes posting it in chat rooms, gaming platforms, social media profiles or online forms that have not been approved by a parent.
Even seemingly innocent conversations can become risky if personal location information is revealed.
Children should understand that their address is private information that should only be shared with trusted adults when necessary.
Phone Numbers
Phone numbers can provide direct access to a child or family members.
Children should know that they should never share their mobile number or home phone number online without parental permission. This applies to social media, messaging platforms, gaming communities and online competitions.
Once a phone number is shared publicly, it can be difficult to control who has access to it.
School Name and Location
Many children are proud of their school and enjoy talking about it. However, sharing school names, uniforms, timetables or locations can reveal more information than intended.
Photos taken in school uniforms or posts mentioning specific schools may make it easier for strangers to identify where a child spends their time.
Parents can encourage children to avoid sharing details that reveal their daily routines or regular locations.
Passwords
Passwords should never be shared with friends, classmates or people met online.
Children often view password sharing as a sign of friendship, particularly in gaming communities. However, passwords protect personal information and accounts.
Teaching children that passwords are private helps prevent unauthorised access and reduces the risk of online scams or account theft.
Parents may keep copies of passwords for younger children, but children should understand that passwords are not for sharing with peers.
Birth Dates
A birth date may seem harmless, but it is often used as a security verification tool.
When combined with a name and other information, a birth date can help someone build a profile of a child or attempt identity-related fraud.
Children should avoid sharing full birth dates publicly unless absolutely necessary and approved by a parent.
Photos That Reveal Too Much
Photos can unintentionally share a great deal of information.
Images that show school uniforms, house numbers, street signs, location tags, identification documents or daily routines may expose more than parents or children realise.
Before posting photos, it is worth checking the background for information that could identify a child's location or personal details.
Financial Information
Children should never share banking information, card details or payment information online.
They should also understand that no legitimate company, game or website should request sensitive financial information directly from them.
Teaching children to involve a parent whenever money is involved online can help prevent scams and fraud.
Information About Family Members
Children may not realise that information about parents, siblings or relatives can also create privacy risks.
Family members' names, workplaces, travel plans or personal details should be treated with the same care as the child's own information.
Online safety often involves protecting the entire family.
Teaching Children to Pause Before Sharing
One of the simplest online safety habits is teaching children to pause before posting or responding.
Encourage them to ask:
- Would I share this with a stranger in person?
- Does this reveal where I live, learn or spend time?
- Could this information identify me or my family?
- Would I be comfortable if anyone could see this?
These questions help children develop critical thinking skills that support safer online behaviour.
Building Safe Digital Habits
The internet is likely to remain an important part of children's lives for many years to come. Rather than focusing only on dangers, parents can help children develop the confidence and knowledge needed to navigate the digital world responsibly.
Open conversations, clear guidelines and regular reminders help children understand that protecting personal information is simply another part of staying safe.
The goal is not to make children fearful of technology. It is to help them become smart, confident and responsible digital citizens who know how to protect themselves and their privacy online.
