Advanced privacy hardening for rooted Android. Hardware-backed encryption, USB/ADB lockdown, surveillance indicator scans, and emergency power-off tools for high-risk travel.
Forensic tools can move fast when a phone is unlocked, outdated, or exposes USB/ADB access. Sentinel reduces that attack surface and helps you keep evidence of device changes.
Built for rooted Android with direct access to hardware security chips and OS-level commands no standard app can reach.
One tap powers your device off. Powering off returns Android storage to its strongest before-first-unlock (BFU) encryption posture. Results still depend on device model, patch level, lock strength, and exploit availability.
Sentinel can disable ADB, revoke trusted computer keys, and force USB into no-data modes where supported. This disrupts tools that depend on stable USB or ADB access while protections are active.
Scans for surveillance indicators such as 2G downgrades, unusual DNS/proxy state, suspicious WiFi conditions, VPN changes, and other network risk signals.
Detects stalkerware, suspicious permission combos, hidden apps, and unauthorized accessibility services on your device.
Keys live inside the hardware security chip where supported, with clear reporting when the device falls back to TEE or software keys. Class A protection — keys clear from memory when the screen locks.
Strips GPS, device serial, timestamps, and all metadata from photos before sharing. One tap. Zero trace left behind.
AES-256-GCM vault with 310K-round PBKDF2 derivation. Unreadable to anyone — even with root — without your password.
Revokes location access from every app at once — including persistent background permissions. One tap, total blackout.
Monitors clipboard reads, auto-clears sensitive content, and alerts you to background clipboard access immediately.
Step-by-step protocol for border crossings, detentions, and high-risk situations. Know exactly what to do under pressure.
Detects unexpected reboots. Automatically locks down USB, ADB, and OEM unlock on next boot before anything can connect.
Real-time posture score across 12 dimensions — bootloader, USB, active threats, and protections. Know your exact risk.
No advanced technical skill required after initial setup. Your seller walks you through the included guide.
You receive a device-bound license cryptographically tied to your specific hardware. Cannot be copied, shared, or transferred without seller authorization.
Sentinel installs as a system app through the Magisk module. Survives user-data resets and cannot be removed through standard Android settings.
Set your password on first launch. All 12 protections activate automatically. Your posture score updates in real time from that point on.
Sentinel uses root via Magisk for hardware-level protections standard apps cannot reach — USB kill, ADB lockdown, StrongBox key generation, bootloader detection. Supports OnePlus, Samsung, Google Pixel, Xiaomi, Motorola, and most other brands.
An honest, item-by-item look at how Sentinel compares to the tools high-risk users actually try first — consumer VPNs, custom ROMs, Magisk privacy modules, and iOS-style spyware scanners.

How to read this: ✓ means first-class, supported feature. Amber text means partial coverage — usually behind manual configuration, a specific device, or third-party setup. We don't claim Sentinel replaces GrapheneOS-grade isolation or a trusted VPN — it sits next to them and covers the surveillance, forensic, and spyware surface those tools were never designed to handle.
Operators, journalists, and security-conscious professionals who use Sentinel daily.
"I've tested every hardening tool on the market. Sentinel is the only one that actually disables ADB and revokes trusted keys at the system level. The Emergency Power Off button alone is worth the price."
"Crossed three borders in two weeks with my source material on this phone. Border Mode + USB lockdown gave me genuine peace of mind that no other app has. Setup was 8 minutes."
"The spyware scanner caught a hidden accessibility service my client's ex had installed during a custody battle. Six months other tools missed it. Sentinel flagged it in 4 seconds."

Sentinel is built by a small independent team with backgrounds in mobile forensics, Android internals, and operational security. We've spent years watching standard hardening tools fail under real adversarial pressure — so we built one that doesn't.
No investors. No data deals. No analytics SDK. Just a tool we'd put on our own phones — and do.
