Black Vault

Mission: Private Storage

"In an era of pervasive surveillance and data harvesting, Black Vault is built on one principle: Your data is your property, and no one—not even us—should have the key."

100% Local Storage Architecture (Zero Cloud reliance)
Absolute Privacy: Zero data upload to any server
Completely Ad-Free experience provided by the developer
Multi-layer Anti-Tamper & Brute-force protection

System Monitor

E2EE Status: ACTIVE

Cipher: AES-256-GCM / XChaCha20

Ads/Trackers: BLOCKING ALL

Initializing Quantum-Resistant Handshake...

Post-Quantum Cryptography

Future-proofing your data against quantum computing threats with Kyber-768 and Dilithium implementations.

Stealth Mode

Allow the app to masquerade as a system utility, requiring a specific secret gesture or PIN on the 'Dummy UI' to access the real vault.

Biometric Binding

Encryption keys are cryptographically bound to hardware-backed Keystore and Biometric prompts, ensuring physical presence.

Vault Lifecycle

01

Isolation

App creates an encrypted container within the internal storage, inaccessible to other apps even with root permission.

02

Key Derivation

Users provide a master passphrase which is hashed using Argon2id to create the high-entropy encryption keys.

03

Encryption

Data is encrypted on-the-fly as it flows into the vault. Keys never touch the persistent storage in plain text.

04

Auditing

Every access attempt is logged with biometric verification. Any tampering triggers an immediate secure lock.
