Advertisements on apps and websites can have a negative effect on a child. Especially in educational apps. When children are concentrated on learning something, advertisements disturb the learning process. In addition, they are often misled and seduced when watching advertisements. Also, it is often determined by algorithms which advertisements are shown. If there is a tablet in the house or at school that is used by several family members, students or teachers, there is a big chance that children will see adverts that are aimed at adults. This is why ScreenTrust allows you to disable ads.
