Secure DNS is an internet service that provides an extra layer of security for your internet activity. It is one of the best ways to make sure that your information is not viewed or recorded by anyone. It works by encrypting the data that is sent from your device to the server. This way, the data that is transferred is protected from unauthorized access.

DNS Changer is a public domain name server app that lets you change the DNS to a secure domain name. It is designed for use with public Wi-Fi and it works in a similar way to the way that DNS works in a normal browser.
