NoteVault — Notes & Hidden Vault
"Looks like Notes. Protects like a vault."
A genuine Material 3 notepad app that conceals an isolated AES-256-GCM encrypted vault. Triggered only by your secret word in the search bar. 100% offline, zero cloud, zero trace.
Anyone with your phone can view your private photos
Standard gallery "hide" options simply move files to a visible hidden album. Ordinary vault apps use obvious disguised icons like fake calculators — making friends, family, or strangers immediately suspicious.
Hidden in Plain Sight behind a Real Notepad
NoteVault looks, feels, and functions as a genuine rich-text notes app. When you type your custom secret trigger word into the search bar, your AES-256-GCM encrypted vault appears instantly.
- 100% Offline — Zero Cloud Servers
- Real AES-256 Cryptography (Not a file rename trick)
- Zero Sign-up & Zero Accounts Required
Complete Architecture & Feature Specifications
Engineered with zero-knowledge cryptographic principles and Material 3 stationery design.
The Disguise — Real Notepad
- Rich-Text Note Editor: Bold, italic, underline, headings, custom fonts, lists, and color themes.
- Checklist Notes & Widgets: Interactive task checklists for daily to-dos and pinned home-screen widgets.
- Organize & Search: Pin notes, archive, labels/tags, instant search filter, grid and list layout.
- Export & Trash Restore: Export notes to PDF or TXT. 30-day trash recovery window for accidental deletions.
The Vault — Security
- AES-256 File Encryption: Streamed file encryption so 1GB+ HD videos encrypt smoothly without lag or memory leaks.
- PBKDF2 Key Derivation: PBKDF2-HMAC-SHA256 with 100,000 iterations to withstand brute-force attacks.
- SQLCipher Encrypted Database: Entire internal database encrypted — even file names, sizes, and metadata are scrambled.
- Hardware-Backed Android Keystore: Master keys generated and protected directly inside hardware security modules (HSM).
- Auto-Lock & Temp Previews Wiped: Decrypted image previews are instantly wiped from RAM upon lock or backgrounding.
Unlock Your Way
- Biometrics & Custom Passwords: Unlock with Fingerprint, PIN, Pattern, or Password. Separate opt-in lock on notepad itself.
- Mandatory Recovery Code: Reset a forgotten password safely without losing a single encrypted file.
- Try-All Recovery Engine: Single recovery master key recovers any forgotten vault password cleanly.
Multiple Isolated Vaults
- Multiple Isolated Vaults: Create separate vaults with independent passwords and cryptographic keys.
- Zero Trace & Separation: Opening Vault A will never reveal or decrypt files in Vault B — perfect for multi-user sharing.
Intruder Protection
- Intruder Attempt Log: Detailed logs with date, time, and failed unlock attempt counts.
- Opt-In Intruder Photo Capture: Captures a photo of unauthorized unlock attempts (off by default, disclosed).
- Lockout Protection: Automatic exponential delays after repeated wrong password entries.
Backup & 13 Languages
- Encrypted .nvbak Backup: Export entire vault to a single passphrase-encrypted .nvbak file to restore on any phone.
- Tamper-Evident HMAC: Streamed backup verification prevents corrupted or manipulated backups from importing.
- 13 Languages: System auto-detect + full Arabic RTL support.
