Capabilities

Nothing leaves.
Nothing leaks.

Every feature engineered around a single principle — your data stays yours, always.

🔐

AES-256-GCM Per-File Encryption

Each file gets its own unique 256-bit key, generated inside the Android Keystore. Keys never leave secure hardware. Streaming encryption means even 4GB files never sit in plaintext RAM.

🔑

Two-Factor Auth

Biometric + mandatory 6-digit PIN. PBKDF2-SHA256 at 100,000 iterations with a 256-bit salt unique per installation.

💣

Panic Wipe

Shake the phone. Every key is destroyed in ~200ms. All files become irrecoverable — permanently and instantly.

🎭

Stealth Mode

Disguise as Calculator, Notes, or System Utilities. Switch icons instantly — the real app stays hidden in plain sight.

🌐

Tor Private Browser

Every browse session routed through Tor. No cookies, no history, no fingerprinting. Starts fresh every time.

📡

Local HTTPS Server

Share vault files to any browser on the same Wi-Fi. Zero cloud. Self-signed HTTPS. QR code pairing.

📷

Direct-to-Vault Camera

Photos and videos captured directly to the encrypted vault. The original never exists in your gallery.

🕵️

Intruder Capture

Silently photographs failed unlock attempts. Stored in vault. They'll never know they were caught.

Security Design

Paranoid
by design.

Every architectural decision starts from a threat model. No plaintext on disk. No key outside hardware. No telemetry, anywhere.

  • No disk image cache — Coil configured memory-only. Decrypted frames never touch storage.
  • FLAG_SECURE global — Screenshots, screen recorders, and recent-app thumbnails blocked everywhere.
  • Zero cloud backupallowBackup=false. All Android extraction rules blocked. No Google Drive sync possible.
  • HTTPS-only networking — Cleartext globally disabled. System CAs only. OS-level enforcement.
  • Zero logcat in release — All logs stripped by R8 + BuildConfig. Zero metadata leaks in prod builds.
  • Auto-lock on background — Vault locks instantly when app leaves foreground. No timeout grace period.
