NoteVault: a real notepad app hiding an encrypted vault behind a secret word

We built NoteVault because private photos, videos, and documents should not be obvious on your phone.

Most “hide” apps just move files into a hidden folder or use a fake calculator disguise. NoteVault is different: it looks and works like a genuine Material 3 notes app, and only reveals the encrypted vault when you type your secret trigger word in the search bar.

What makes it different:

• 100% offline, zero cloud, zero accounts

• AES-256-GCM encrypted vault

• Real notes app on the outside, private vault on the inside

• Fingerprint, PIN, pattern, and password unlock

• Multiple isolated vaults

We are on Google Play and would love feedback from the Product Hunt community on the UX, positioning, and what would make this more useful or trustworthy.

Happy to answer any questions and share what we learned while building it.
