Password Protect Any Windows App & Folder. Stop Snooping on Shared PCs
PrivaGuard lets you lock sensitive apps like WhatsApp, Chrome, and private folders with a Master Password or PIN. If someone enters the wrong password, it secretly captures their photo using your webcam.
Why Windows Login Security Is Not Enough
Once you log into Windows, every application sits wide open. Leaving your workstation unattended for 30 seconds exposes your private conversations, browser cookies, and confidential documents to anyone nearby.
You step away for coffee.
Your entire digital life is
exposed.
It takes less than 30 seconds for an intruder, co-worker, or snooper to read your private conversations, extract browser session cookies, and copy API tokens from an unlocked PC.
Engineered from the Kernel Up for Absolute Windows Defense
PrivaGuard combines zero-knowledge encryption, silent biometric capture, anti-tamper process shielding, and public hardware sentinels to deliver security no ordinary app locker can match.
Zero-Knowledge AES-256-GCM Encryption
We don't just hide your applications and folders; we mathematically encrypt them. PrivaGuard utilizes the exact cryptographic standard trusted by defense agencies worldwide. Without your master password, decryption would require millions of years even with modern supercomputers.

Catch Snoopers Red-Handed with Silent Intruder Snaps
Ever wondered if someone tried to guess your PIN or snoop on your private chats while you left your laptop unattended? The moment an incorrect password is entered, PrivaGuard silently snaps a high-res photo using your webcam without making a shutter sound.
Unkillable Protection: Auto-Locks Windows Task Manager
Savvy intruders frequently try to bypass security apps by opening Windows Task Manager or Command Prompt to force-kill background processes. PrivaGuard actively monitors the OS process tree—if Task Manager or cmd.exe is summoned, it immediately intercepts and locks the screen before termination can execute.
Public Laptop Safety: Charger Unplug Siren Alarm
Working in a bustling coffee shop, university library, or airport lounge? Arm the PrivaGuard Charger Sentinel. The split-second someone unplugs your laptop cable or detaches your security USB drive, an ear-piercing 105dB siren sounds and your screen locks instantly—preventing grab-and-run physical theft.

Everything you need to know about our cryptographic architecture, anti-tamper security, and local zero-cloud privacy.
Not in the slightest. PrivaGuard is written in highly optimized native C++ utilizing Windows kernel events. In passive sentinel mode, it consumes under 12MB of RAM and virtually 0.02% CPU, making it undetectable to system performance and laptop battery life.
Standard app lockers fail because intruders simply right-click "End Task". PrivaGuard features an active Kernel Process Watchdog. The split second Task Manager, Command Prompt, or PowerShell is spawned to terminate the process, PrivaGuard intercepts the call and immediately locks the display with AES-256 protection.
Never. PrivaGuard operates on a strict zero-telemetry architecture. All encryption keys, salted password hashes, and intruder capture photos remain 100% on your local disk. We operate zero activity tracking servers and internet access is used strictly for license activation, updates, and emergency alert emails.
You can configure automated idle locking from 30 seconds to 5 minutes, or lock everything instantly with a custom global hotkey (default: Ctrl + Shift + Alt + P). The moment you return, unlock with your Master Password or PIN in 0.008s.
