Staying safe online · Lesson 3 of 5

Your privacy and digital footprint

What you share online can last and travel further than you expect. Think about who might see it, now and years from now.

Free — no account needed to read

Every post, photo, comment and profile adds to your digital footprint: the trail of information about you that others can find. Much of it is harmless. But some of it, such as your address, your daily routine, your children's school, or your date of birth, can be used by people you would never choose to share it with.

Check the privacy settings on the apps you use most, and review what is public. Be careful with location sharing and with photos that show where you live or when you are away. Remember that screenshots mean even private messages can be shared.

It helps to ask a simple question before posting: would I be comfortable with this being seen by a future employer, a stranger, or myself in ten years? This is not about fear, but about choosing on purpose what the world can know about you.

See it happen

Before a family holiday, Rahim posts publicly that the house will be empty for two weeks, with photos of the airport and a tag showing his home neighbourhood.

The first reaction

He is excited about the trip and wants to share it with friends, and the post is just a normal holiday update.

With the idea

He switches the post so only close friends can see it, removes the neighbourhood tag, and shares most of the holiday photos after coming home. His friends still enjoy them, and nobody else learns the house is empty.

What changed

He thought about who could see the post and what it revealed before sharing it.

Easy to take the wrong way

Protecting your privacy does not mean hiding from the internet or never sharing anything personal. It means deciding on purpose who sees what, rather than leaving it to default settings.
