Black & orange browser on the GeckoView engine (Firefox tech). DuckDuckGo search, uBlock Origin ad blocking, popup blocking. Private use only — not for redistribution.

Toggle it on and off from the big button in the app. On = the phone is told to resolve names through this app, and requests to known ad, tracker and malware domains are answered locally so they never leave the device. Off = the tunnel is torn down and DNS flows exactly as it did before.

It is not a VPN: no traffic is routed, nothing is decrypted, and no browsing is hidden. A browser using its own “Secure DNS” (DoH) resolves names itself and goes around it, and IPv6-only networks are not covered. 74,758 domains on the list.
