Cost traps on the Internet are often just a click away - even or especially in free apps. These are usually financed by advertising, where subscription traps can be disguised as simple ads. One tap and, in the worst case, you've taken out a subscription without meaning to. In-app purchases also pose a risk. Children and young people in particular can quickly lose track of how much they spend on games apps, for example.
Inga Pöting from mobilsicher shows in the fourth part of our joint video series "mobil & safe" how you can protect yourself and your children from cost traps when using your smartphone.
