About this app

VaultSeal is an offline-first, zero-knowledge encrypted vault designed to give you complete control and uncompromising privacy over your personal media, documents, and notes.

Protect your private photos, sensitive videos, confidential PDF documents, audio recordings, and private notes with authenticated AES-256-GCM encryption. VaultSeal operates 100% offline directly on your device. There are no cloud servers, no account logins, no tracking, and no external data collection.

Your secrets stay in your hands — fully encrypted, private, and secure.


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.

🛡️ Built-in Privacy & Defense-in-Depth
- Screenshot & Recents Protection: Blocks unauthorized screen grabs and blanks the app preview in Android's app switcher.
- Metadata Purifier: Strip sensitive EXIF data, GPS coordinates, and camera timestamps before exporting images.
- Clipboard Sentinel: Securely ingest clipboard text into vault notes with automated clipboard clearing.
- In-App Secure Camera: Snap photos and videos directly into your vault without leaving unencrypted copies in your public gallery.
- Auto-Seal Timer: Automatically locks and purges memory keys after 1, 2, 5, or 10 minutes of inactivity.

💾 Full Storage Access Framework (SAF) Control
Choose exactly where your encrypted container lives on your device or external SD card. Your encrypted container file survives app uninstalls, making backups and migrations easy.
