KEY FEATURES 🔒 Zero-Knowledge Cryptography Every item placed into VaultSeal is protected with authenticated AES-256-GCM encryption. Your master encryption key is derived from your passphrase and lives in volatile memory only while actively browsing. The moment your vault seals or times out, the decryption keys are wiped from memory. ⚡ Dual-State Operations (Sealed & Unsealed) - SEALED INGEST: Seamlessly import photos, videos, clipboard text, and shared files from other apps directly into your encrypted vault without ever unlocking or decrypting existing data. - UNSEALED BROWSING: Unlock with your passphrase or biometric credentials to explore, preview, organize, and export your files. 📁 Flexible Folder Navigation & View Modes Organize your encrypted files with nested folders, favorites, and categorized filters. Browse your content your way with three customizable display modes: - List View: Clean, high-density file listing with metadata details. - Icons View: Compact desktop-style grid layout. - Large Icons View: Rich gallery preview cards with thumbnail previews. 💻 PC Pairing, Sync & Desktop Compatibility (Windows & Linux) - Direct LAN Pairing & Sync: Effortlessly sync your encrypted vaults between your Android device and the VaultSeal PC app over your local Wi-Fi / LAN with zero cloud servers or third-party exposure. - Cross-Platform Binary Compatibility: Transfer `.vseal` containers between Android, Windows, and Linux seamlessly.
