MantisGuard - Ad Blocker

MantisGuard is an all-in-one DNS firewall that blocks ads, trackers, malware, and inappropriate content — all without rooting your device or sending your browsing data to the cloud.
Built on a local, on-device VPN engine, MantisGuard filters DNS requests directly on your phone. Your traffic stays yours.
AD & TRACKER BLOCKING

Strip out ads, analytics trackers, and data-harvesting domains across every app on your device, not just your browser.
THREAT INTELLIGENCE

On-device threat detection flags malicious and phishing domains in real time, using regularly updated blocklists and local geo-IP intelligence to identify risky connections before they load.
PARENTAL CONTROLS

Apply per-app and per-profile filtering to manage what your family can access, with simple toggles instead of complicated router settings.
PRIVACY GUARD

See exactly which domains your apps are contacting, and shut down the ones you don't recognize or trust.
DESIGNED FOR YOUR ROUTINE

• Quick Settings tile to toggle protection without opening the app

• Home screen widget for at-a-glance status

• Tasker integration for automation power users

• Biometric lock to keep your filtering profiles private

• Clean, modern Material You interface that adapts to your device's theme
WHY MantisGuard

Most ad blockers require root access or route your traffic through a third-party server. MantisGuard runs its firewall locally on your device, so your DNS queries never leave your control.
Upgrade to Pro to remove ads entirely and unlock advanced filtering profiles.
Note: MantisGuard works by creating a local VPN connection on your device purely to filter DNS traffic. No data is routed through external servers, and your VPN permission is used solely for on-device content filtering.
