The Problem

Standard Android
leaves you exposed.

Forensic tools can move fast when a phone is unlocked, outdated, or exposes USB/ADB access.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.

Without Sentinel
  •  USB connects — forensic tool launches immediately
  •  ADB exploited — full filesystem dump in minutes
  •  Spyware runs silently in background
  •  GPS coordinates in every photo you share
  •  Unexpected reboots go undetected
With Sentinel
  •  USB/ADB lockdown reduces stable forensic access
  •  ADB can be disabled and trusted computer keys revoked
  •  Known spyware and suspicious indicators are flagged
  •  EXIF tools help remove sensitive photo metadata
  •  Unexpected reboot can trigger lockdown and alerts
Features

12 layers of protection.
One app.

Built for rooted Android with direct access to hardware security chips and OS-level commands no standard app can reach.

★ Flagship

Emergency Power Off

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.

🔌

USB Lockdown

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.

📡

Network Surveillance Indicators

Scans for surveillance indicators such as 2G downgrades, unusual DNS/proxy state, suspicious WiFi conditions, VPN changes, and other network risk signals.

🕵️

Spyware Scanner

Detects stalkerware, suspicious permission combos, hidden apps, and unauthorized accessibility services on your device.

🔐

StrongBox Encryption

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.

📸

EXIF Scrubber

Strips GPS, device serial, timestamps, and all metadata from photos before sharing. One tap. Zero trace left behind.

🗄️

Encrypted Vault

AES-256-GCM vault with 310K-round PBKDF2 derivation. Unreadable to anyone — even with root — without your password.

📍

Location Kill Switch

Revokes location access from every app at once — including persistent background permissions. One tap, total blackout.

📋

Clipboard Guard

Monitors clipboard reads, auto-clears sensitive content, and alerts you to background clipboard access immediately.

✈️

Border Mode Guide

Step-by-step protocol for border crossings, detentions, and high-risk situations. Know exactly what to do under pressure.

🔁

Reboot Guard

Detects unexpected reboots. Automatically locks down USB, ADB, and OEM unlock on next boot before anything can connect.

📊

Live Privacy Score

Real-time posture score across 12 dimensions — bootloader, USB, active threats, and protections. Know your exact risk.

How It Works

Up and running
in 10 minutes.

No advanced technical skill required after initial setup. Your seller walks you through the included guide.

1

Purchase your license

You receive a device-bound license cryptographically tied to your specific hardware. Cannot be copied, shared, or transferred without seller authorization.

2

Install via Magisk

Sentinel installs as a system app through the Magisk module. Survives user-data resets and cannot be removed through standard Android settings.

3

Activate protections

Set your password on first launch. All 12 protections activate automatically. Your posture score updates in real time from that point on.

⚠️

Rooted Android device required

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.

FAQ

Common questions.

Does my phone need to be rooted?
Yes. Sentinel requires root access via Magisk to enforce hardware-level protections standard apps cannot reach — USB kill at the OS level, hardware key generation, ADB lockdown, and bootloader detection. The included buyer guide walks you through everything.
What Android devices does it support?
Any Android device running Android 9 or newer with Magisk root — OnePlus, Samsung, Google Pixel, Xiaomi, Redmi, POCO, Motorola, and many more. Sentinel auto-detects your manufacturer and shows device-specific security guidance tailored to your hardware.
Does it actually stop Cellebrite?
Sentinel is designed to reduce common logical-extraction paths by disabling ADB, revoking trusted computer keys, and forcing USB no-data modes where supported. Emergency Power Off returns the phone to before-first-unlock encryption state, which is the strongest normal Android storage posture. No app can guarantee protection against every exploit, forensic lab, carrier-level process, or physical attack.
Can I transfer my license to a new phone?
Licenses are cryptographically bound to your device's hardware identifiers for security. If you get a new device, contact your seller for a reissue.
Will it drain my battery?
Minimal impact. Sentinel batches all root commands into single sessions, caches the privacy score for 30 seconds, and uses a lightweight background service. Most users report no noticeable change in battery life.
Is this legal to use?
Yes. Sentinel is purely defensive — it hardens your own device against unauthorized access to your own data. Encrypting your own storage and protecting your own device is legal in virtually all jurisdictions worldwide.
What happens if someone forces a reboot?
Sentinel's Reboot Guard detects unexpected reboots. On next boot it automatically locks down USB, disables ADB, hardens OEM unlock, and sends a persistent alert — all before any forensic tool can establish a connection.
