Great question!

In most cases, your phone picks up the system resolver when it connects to a cellular or a WiFi network.

The system resolver collects data about what websites you are visiting by looking at the DNS queries your phone is making. This can lead to targeted advertising by your ISP.

1.1.1.1 is a privacy-first resolver, it does not collect any private information.
