NetShield is a local DNS resolver, ad/tracker sinkhole, and real-time traffic monitor for Android. Features: * Two operation modes: a device-wide local VPN sinkhole, or a local UDP DNS server on 127.0.0.1 for custom apps/routers. * DNS-over-HTTPS, DNS-over-TLS, and plain UDP upstream resolvers. * Custom and built-in blocklists for ad/tracker sinkholing, with pause controls (5/15 minutes) and per-app split tunneling. * Real-time traffic dashboard, live query logs, and per-domain rules. * Quick Settings tile and a home-screen widget to toggle protection with a single tap. * Import your own OpenVPN/WireGuard server configs to manage alongside the resolver (importing and managing profiles only for now - no bundled server list, and tunneling through them is not yet implemented). No ads, no analytics, no tracking, no non-free dependencies.
