What is NoteVault?

NoteVault is an Android privacy app built by ZeengoCorp Innovations. It looks like a Material 3 notepad — and conceals an encrypted vault for photos, videos, and documents behind a secret trigger word that only you know. NoteVault runs 100% offline, requires no account, uses SHA-256 password hashing with Android Keystore-backed encryption, and is available free on the Google Play Store.

What makes NoteVault different.

100% Offline

No accounts. No cloud. No internet required. Your vault never leaves your phone.

Disguised as a Notepad

Looks and behaves like a real notes app. The vault only appears when you type your secret trigger word into the search bar.

Password-Only

No biometric data collected. Password and trigger word are SHA-256 hashed. You stay in control of access.

Encrypted at Rest

Files are stored in Android's encrypted storage with hardware-backed Keystore where available. Vault thumbnails are encrypted previews.

How it works

Six steps from notepad to vault.

  1. 01

    Open NoteVault — it looks like a notes app.

  2. 02

    Set up your password, trigger word, and recovery code.

  3. 03

    Use it normally as a notepad — take real notes.

  4. 04

    When you need the vault, type your trigger word in the search bar.

  5. 05

    The vault unlocks — hide photos, videos, anything private.

  6. 06

    Type "lock" or leave the screen — the vault disappears.

Inside the product

A real notepad. A serious vault.

A Real, Usable Notepad

Rich-text formatting, labels, pinning, archive, full-text search, color-coded notes, reminders, trash with undo. The disguise isn't a trick — it's a notepad you'd actually use.

The Hidden Vault

Type your secret word into the search bar and the notepad transforms. Hide unlimited photos, videos, audio, PDFs, and documents. Files vanish from your gallery — completely. Export back any time.

Built for Real Privacy

Mandatory recovery code so you never lose access. Intruder log captures every failed unlock attempt with timestamps. No telemetry of your content. No email, no phone number, no sync.

Built on Flutter

Native Android performance. SQLite vault index, encrypted local file store, Play Integrity API for tamper protection, anonymous Crashlytics for stability only. Minimal scoped Android 13+ permissions.
