Tamper-Proof Content Blocker & Device Protection App

System-Level Mobile Threat Protection & Local Network Filtering

The Challenge

Standard Android content filters are easy for users to bypass, disable, or uninstall, while third-party remote VPNs introduce severe latency and data privacy risks.

The Solution & Impact

Built a Kotlin-native Android application that enforces device-level content filtering and anti-tampering protection locally without sending user traffic to external servers.

Local VPN & DNS Filtering: Intercepts system-wide DNS packets via a local VpnService TUN interface to block prohibited domains locally with zero latency.

System-Level Security Hooks: Utilized Android Accessibility Services and Device Admin APIs to prevent unauthorized uninstallation, force-stopping, or setting bypasses.

Tamper-Proof Lock: Enforced settings locking via an encrypted, randomized password generator to ensure non-bypassable enforcement.

Tech Stack: Kotlin | Android SDK | VpnService | Accessibility APIs | DeviceAdminReceiver | Jetpack Compose

Doing the DNS filtering locally through VpnService instead of routing traffic out is the right call. Curious how the Accessibility Services and Device Admin combo went with Play review, that pairing usually draws a lot of policy questions on anti-uninstall apps.
