Unlock with your voice

Say your secret phrase and the vault opens. Recognition runs on your iPhone when your language supports it.

🔐

Encrypted on device

Photos and notes are sealed with AES-256-GCM. The key lives in your iPhone's Keychain and never leaves it.

🖼️

Private photo vault

Move photos out of your library into the vault, then remove the originals from Photos if you like.

📝

Secret notes

Keep passwords, ideas and anything personal in notes only you can open.

Face ID and PIN backup

Can't speak out loud? Use Face ID or your 6-digit PIN. Forgot the PIN? Reset it with your iPhone passcode.

👀

Hidden when you switch

The vault locks when you leave and stays covered in the app switcher.

How it works

  1. Create a backup PIN. Six digits you'll use if voice or Face ID can't unlock.
  2. Pick a secret phrase. Two or more words that are easy for you to say and hard to guess. Say it once so the app knows your iPhone hears it.
  3. Add photos and notes. Everything you add is encrypted before it's saved.
  4. Open it by voice. Next time, just say your phrase on the lock screen.
Good to know: Voice Unlock protects what's inside this app. It doesn't replace or change your iPhone's own lock screen. A spoken phrase is convenient, not unbreakable — anyone who hears it can repeat it, so use Face ID or your PIN when others are around.
