Why should you protect your data?
Imagine walking around every day with your passport, keys, phone and all your bank statements in your hands – and often putting them down in public without a thought. Most people would call that careless.
Yet that's exactly what many people do digitally without realising it.
Every time we click “accept”, log in, share photos or send a message, we leave traces – digital data that reveal who we are and what we do. And those are the data we need to protect.
What is "data" anyway?
Many people think, “I have nothing to hide.” But it's not about hiding anything – it's about keeping control of your own information. Your data isn't just technology. It's you. It's your life.
- Your name and address
- Your social security number
- Your email and phone number
- Your photos and videos
- Health information
- Conversations and messages
- Your searches and clicks online
- Where you are and who you're with
When we say data is valuable, it's not just to scare you. Your details can be misused for identity theft, financial fraud, extortion, and even manipulation. For example, a hacker might use your name and photo to create a fake profile. Or they can get into your email and reset your passwords elsewhere – getting access to even more of your information.

Information is valuable
Sometimes it's not about money, but about power. Companies and networks collect and analyse people's digital habits to influence what we buy, vote for or believe. Your data can be used to draw a very precise picture of you – without you ever being asked.
It's also important to understand that you're not only protecting yourself. If your information leaks, it can also affect your friends, family or colleagues. A single innocent contact list, photo or message can be enough for others to be harmed.

What can you do yourself?
Fortunately, protecting your data doesn't have to be hard. It's mostly about being aware and adopting some good digital habits. For example:
- Use strong, unique passwords – preferably with a password manager
- Enable two-step verification (2-factor login) wherever possible
- Think before clicking on links or attachments in emails
- Be critical when installing apps or signing up for new services
- Don't share more on social media than you'd put on a postcard
- Keep your phone and computer updated with the latest security patches
In short
- Taking care of your data is a bit like locking the door when you leave home.
- It doesn't mean you expect a break-in – it simply means you're protecting what belongs to you.
- We shouldn't be afraid of technology. We just need to use it thoughtfully.
And when we learn to protect our data, we learn to protect ourselves – and each other.
