Quad9 Connect

Android application for Quad9 recursive DNS cybersecurity and privacy services
New in version 1.1.0
- Trusted Networks: Fixed a bug when trying to add a Trusted Network while on Mobile data would add a null entry to the list. Now an error message will display that the device must be connected to WiFi to add a Trusted Network.

Quad9 Connect is an Android and ChromeOS app that sends your DNS queries to Quad9's secure, private, open recursive DNS service.

Quad9 Connect adds additional functionality and features compared to using Android's Private DNS feature to utilize encrypted DNS or configured Quad9 in Chrome on ChromeOS.

The application creates a split VPN tunnel with Android API "VpnService" to configure an alternate DNS server on Android and ChromeOS.

## Features
- DNS over TLS or DNS over UDP
- DNS Query Log
- Trusted Networks
- Blocked Query Notifications
- Local Domains
- Excluded Applications
