Store listing
By Crystal Digital Labs, from Google Play“AES-256 encrypted file vault with icon disguise. Persistent offline protection.”
Description by Crystal Digital Labs Written by the developer, not by AppBrain. Click to read.
Built on a Zero-Knowledge architecture, File Encryption locks files with AES-256-GCM encryption in the proprietary .armor format. Because your vault resides in persistent local storage, your encrypted files stay safe and recoverable even if the app is accidentally uninstalled.
💡 WHAT MAKES THIS APP UNIQUE?
• Survives App Uninstall: Unlike standard vault apps that delete your data upon uninstall, your .armor files remain safe in your local storage. Reinstall anytime, enter your master PIN, and your data is restored instantly.
• Corrupt & Junk to the Outside World: Encrypted .armor files become completely unintelligible. To file managers, OS scanners, and external apps, the file appears as unreadable, corrupted junk code that cannot be opened.
• All-in-One Professional Sandbox: Open and preview Excel spreadsheets, JSON code, and top 10 document formats natively—eliminating the need to install risky third-party viewers.
• 100% Offline & Zero-Knowledge: No user accounts, no cloud sync, and no tracking servers. Your encryption keys stay strictly on your device.
KEY FEATURES:
🛡️ Military-Grade AES-256-GCM Encryption
• Exclusive .armor Lock: Files can only be opened and reconstructed by this app. To all other software, the file appears as corrupt data.
• Batch Processing Engine: Encrypt hundreds of documents or media files simultaneously with zero system lag.
🎭 Functional Premium Disguises
• Hide in Plain Sight: Disguise the vault as a fully operational World Clock, Compass, Crystal Notes, Speedometer, or Network Speed Test.
• Travel & Utility Ready: Premium disguised interfaces function as real utility tools while keeping your private files hidden behind a secret trigger.
🔒 Isolated Professional Sandbox Viewer
• Universal Format Support: Preview Excel (.xlsx, .xls), JSON, PDFs, and top 10 professional documents directly inside the app.
• No Third-Party Viewers Needed: Eliminate data leaks caused by external document viewers or cloud caching.
• Zero Cache Leaks: Strictly isolated sandbox prevents OS thumbnails, clipboard caching, and data indexing.
📁 Persistent Offline Storage
• Accidental Deletion Protection: Encrypted .armor files stay safe even through app deletions and system cleanups.
• 100% Local Control: Your encrypted files remain on your device until you choose to delete them.
📲 Encrypted P2P Offline Transfer
• Air-Gapped File Sharing: Send encrypted files directly between devices without internet connection or cloud servers.
🚫 Zero-Knowledge Security
• No Accounts, No Tracking: No signups, no remote servers, and no telemetry.
• Complete Privacy: Your master keys and passwords never leave your device.
