Block This! is a DNS/VPN based ad blocking & privacy app for Android, that blocks malicious or unwanted internet content by filtering DNS requests and redirecting them to 127.0.0.1 (localhost). It uses a dummy VPN client in order to go around the restrictions in Android and change the DNS settings without having root access. The backend behind the app is a DNS based on PowerDNS - an open source DNS management software working with MySQL as a datasource.
Tracking: The application tracks and reports your activity to somewhere – usually either without your consent, or by default (i.e. you’d have to actively disable it). It’s commonly used for when developers obtain crash logs without the user’s consent, or when an app is useless without some kind of authentication.
