The internet offers you great opportunities: You can share pictures or videos, chat with friends or even study for school together with your classmates. Networks such as Facebook and WhatsApp make it possible. Millions of people maintain their friendships on social networks via the internet. And what so many people are doing is surely a good thing - right?

However, you should think carefully about what information you put online about yourself or others. After all, a photo or text cannot simply be deleted. Imagine how embarrassing it can be if people can still see things from several years ago in your profile today. You never know who will find the data later. Your friends? Teachers? Parents?

Most of you who already have a mobile phone also use WhatsApp. But maybe you've already experienced unpleasant things on WhatsApp? For example, you or your friends have been insulted? The lecture will also give you tips on how you can make security settings to protect yourself better.
