Your Face is the Key.
Your Vault Stays On Your Phone.
FaceLock Vault locks your private photos, videos, confidential documents, and encrypted notes behind front-camera face recognition and military-grade AES-256-GCM encryption. No accounts, no servers, no ads.
Engineered For Zero Data Leakage
Unlike cloud-based vaults that upload your private files and face biometric data to remote servers, FaceLock Vault strips network permissions directly from release builds. What happens on your phone stays on your phone.
-
✓Local Biometric Inference: Powered by TensorFlow Lite and Google ML Kit entirely in memory. Raw camera frames never touch disk unencrypted.
-
✓Hardware-Backed Cryptography: Master encryption keys reside inside the Android Keystore / Trusted Execution Environment (TEE).
-
✓Silent Intruder Selfies: Automatically snapshots unauthorized unlock attempts after 3 consecutive failures.
-
✓Anti-Spoofing Challenges: Interactive liveness challenges (blink, head rotation, smile) defeat static printed photo attacks.
Designed for Complete Sovereignty
Six layers of privacy and security safeguarding your personal assets.
AES-256-GCM Vault
Every photo, video, PDF, document, and text note is encrypted with a unique random 96-bit initialization vector (IV) and verified with a 128-bit authentication tag.
100% Offline Promise
No internet permission in production builds. Zero cloud synchronization, zero third-party analytics, and zero ad networks. Your secrets cannot leave your phone.
Real-Time Liveness Engine
Anti-spoofing challenge state machine randomizes blink, turn, and smile tests to prevent unauthorized unlock using printed photos or stationary digital displays.
Intruder Selfie Catcher
Failed authentication attempts trigger an escalating lockout timer. After 3 repeated failures, a silent front-camera selfie is recorded to local encrypted logs.
24-Word Offline Recovery
A standard cryptographically secure offline recovery phrase allows you to reset your master PIN offline even if biometric hardware changes, without backdoors.
Instant Secure Purge
Wipe all biometric templates, encrypted vault items, intruder snapshots, and cryptographic keys in seconds with our verified in-app "Delete All Data" feature.
Common Questions & Answers
Clear, direct answers regarding encryption, permissions, and app behavior.
What data is stored by FaceLock Vault?
FaceLock Vault stores your imported photos, videos, confidential documents, encrypted notes, and local biometric face embeddings. All data is encrypted on your device using hardware-backed AES-256-GCM. Personal data or raw camera photos are never stored unencrypted.
Is any data uploaded to the cloud or remote servers?
No. FaceLock Vault operates 100% offline. There are zero cloud servers, zero analytics SDKs, zero ads, and zero telemetry. In production release builds, internet permissions are permanently stripped from the app manifest.
What permissions does the app request and why?
• Camera: Used strictly on-device to capture your face for biometric authentication and optional intruder selfies upon failed attempts.
• Vibrate: Used for tactile haptic feedback during PIN keypad entry.
• Photo Picker / Media: Used solely when you choose to import media or export files to your device Gallery. The app never scans other private folders and does not request broad storage permissions like MANAGE_EXTERNAL_STORAGE.
How do I export files out of the vault to my phone?
Go to the Vault tab, tap "Export", and select the items you wish to save. When exported, photos and videos are saved directly to your phone's Gallery or Photos app, and documents are saved to your chosen folder. Exported files are safely removed from the encrypted vault.
How do I permanently delete all data and reset the app?
Go to Settings > Delete All Data. You will be prompted to type "DELETE" to confirm. This completely purges all encrypted vault files, intruder photos, hardware keystore keys, and database settings. You can also review our detailed Data Deletion Policy online.
What happens if I forget my Master PIN?
During initial setup, an offline recovery phrase was generated. You can use this recovery key on the lock screen to reset your PIN offline. Because the app has no cloud sync, nobody else can recover your PIN.
Does this app unlock my entire mobile phone?
No. FaceLock Vault is a private encrypted container for files and notes inside this application. It does not replace your Android system lock screen or system-level security.
