SonderShield

Ad, tracker and malware blocker for Android, Windows and Linux. DNS filtering, HTTPS filtering, WireGuard, firewall. No account, nothing leaves your device.

Features Blocks everywhere Every app on the phone, through a DNS-only VPN. No speed or battery cost from routing. Good lists, ready StevenBlack, AdGuard (DNS, Base, Mobile, Tracking, Social), EasyList, uBlock Origin, HaGeZi, OISD, URLhaus, Phishing Army, plus regional lists switched on for your language. Add any list by URL (hosts, AdBlock or plain domains). Your rules win Block or allow any domain, subdomains included. Test a domain to see which list or rule decides. HTTPS filtering Hides ads inside pages in the browsers you pick, with element hiding and scriptlets from the lists. Uses a certificate made on your phone. Banks, payments and government sites are never touched. Encrypted DNS DNS over HTTPS with Cloudflare, Quad9, Google, AdGuard, or your own server. WireGuard Import a .conf and your traffic leaves through your own server or VPN provider, still filtered. Root mode On rooted phones, blocks without a VPN so another VPN can run alongside. Live log Every lookup, with the app that asked. Search, filter, and block or allow from a tap. Per-app control Let an app that breaks skip SonderShield, or cut an app off the internet entirely (firewall). Profiles Default, Strict, Family, Gaming or your own set of lists, switched by hand or on a schedule. Data monitor Mobile and Wi-Fi use today and this week, your data plan with what's left per day, and how much each app used.
