Salfeld Child Control is a parental control app that provides safe and filtered internet access to children. This app runs on Android phones and tablets and can be tuned from any PC with any OS connected to the internet. It comes with a 30-day free trial, and after that, a license is required. The app uses the Device Administrator permission to prevent a user from uninstalling Salfeld Child Control without parental knowledge. Additionally, it uses AccessibilityService API to collect data about websites viewed through browsers on the child's device and prevent the child from removing permissions without parental authentication.

The app provides a safe internet experience for children by allowing parents to filter content and limit access to specific websites. The app also provides a time management feature that enables parents to set limits on how long their children can use the internet. With Salfeld Child Control, parents can ensure their children's online activities are safe and secure.
