Opaque

Opaque is a uniquely strong file vault that stores almost any file with multiple layers of security.
Highlight the Core Features:
🔒 Zero-Knowledge Architecture: Stored files are mathematically scrambled using AES-256 GCM encryption.
🛑 No Internet Required: Store your files entirely offline. Opaque does not use or require internet access, and your files will never go anywhere but your vault.
🎭 Plausible Deniability: Forced to unlock your phone? Create a "Duress PIN" to open a fake vault which you can populate with decoy files.
📸 Secure Camera & Notepad: Take photos and write notes directly into encrypted memory. Files never touch your public gallery and will not be shared to other folders. Opaque automatically scrubs all GPS and tracking metadata from your photos before saving them.
⚠️ Emergency Shredder: A panic PIN that instantly overwrites and silently shreds all files in your primary vault while leaving the vault's infrastructure intact, dropping you into the "duress" decoy vault. Shredded files are overwritten with random data, re-encrypted, and then destroyed.
🔑 Seed Phrase Recovery: Forget your PIN? Recover your vault using an offline, 24-word cryptographic seed phrase.
