โšก Full Feature Breakdown

Built to protect.
Designed to deceive.

Every feature has been engineered with one goal: your privacy is absolute, and no one will even suspect a vault exists.

๐Ÿงฎ Feature 01

The Perfect Decoy Calculator

  • Memory functions: MC, MR, M+, Mโˆ’
  • Swipe left/right on display to delete last digit
  • Double-tap display to copy result to clipboard
  • Calculation history panel accessible via clock icon
  • Haptic feedback on every keypress
  • Secret unlock: type your PIN โ†’ press = โ†’ vault opens silently

AES-256-GCM Hardware Encryption

Every file entering the vault is encrypted immediately using AES-256-GCM โ€” the same standard used by governments and financial institutions. Your encryption keys never leave the device's secure hardware.

  • AES-256 bit keys with Galois/Counter Mode (authenticated encryption)
  • Keys generated and stored inside Android KeyStore (Hardware Security Module)
  • Keys are never exposed to app memory โ€” decryption happens at hardware level
  • Files stripped from Android Gallery the moment they enter the vault
  • Hidden in the app's private directory โ€” inaccessible without root
  • Room DB metadata protected with SQLCipher database encryption

App Locker with Fake Crash

Lock any installed app โ€” WhatsApp, Instagram, your gallery, email. When an intruder tries to open it, they see a convincing Android crash dialog. They assume the app crashed. You bypass it with your secret gesture.

  • Runs as an Accessibility Service (background monitor)
  • Detects foreground app changes in real-time
  • Replaces screen with a fake "App has stopped" dialog
  • Intruder sees: "Close App" or "Open App Again" โ€” both go nowhere
  • You bypass the overlay with a hidden gesture only you know
  • Works on most Android apps including social media, banking, gallery

Active Anti-Intruder Protocols

Stealth Vault doesn't just protect passively โ€” it fights back. Every failed access attempt is silently logged, photographed, and counted. Persistent attackers trigger a complete data wipe.

  • Intruder Selfie: CameraX silently takes a front-facing photo on every wrong PIN
  • Decoy PIN: Secondary PIN opens a clean, empty dummy vault
  • Emergency Wipe: 5 failed attempts โ†’ permanent deletion of all vault data
  • Timestamp and attempt count logged locally for each intrusion
  • Decoy vault looks identical to the real vault โ€” just empty
  • Wipe erases encryption keys, database, and all encrypted files
