Works for Scanner Vault PDF & OCR Scan whether or not it has its own passcode. No download needed.

Short answer

Touch and hold Scanner Vault PDF & OCR Scan's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Scanner Vault PDF & OCR Scan behind Face ID, Touch ID or your passcode; choose Hide and Require Face ID instead to move it into App Library's Hidden folder as well.

Lock Scanner Vault PDF & OCR Scan with Face ID

  1. Find Scanner Vault PDF & OCR Scan on your Home Screen or in App Library.
  2. Touch and hold the icon until the quick-actions menu opens.
  3. Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
  4. Tap Require Face ID again to confirm. Scanner Vault PDF & OCR Scan now asks for authentication every time it opens.

To test it, close Scanner Vault PDF & OCR Scan from the App Switcher and open it again. You should see the Face ID prompt before any content appears.

Hide Scanner Vault PDF & OCR Scan in App Library

  1. Touch and hold Scanner Vault PDF & OCR Scan's icon and tap Require Face ID.
  2. Choose Hide and Require Face ID instead of Require Face ID.
  3. Confirm. The icon leaves your Home Screen and moves to the Hidden folder at the bottom of App Library.
  4. To open it later, swipe to App Library, tap Hidden and authenticate.

Hiding also locks the app. To undo either, touch and hold the icon again and choose Don't Require Face ID.

Why lock Scanner Vault PDF & OCR Scan?

Scanner Vault PDF & OCR Scan is a photo vault, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. A photo vault holds the pictures you least want seen, so the questions that matter are where the files live, whether they are encrypted, and what happens if you forget the PIN or change phones.

Business apps often handle other people's data — clients, colleagues and customers — so what they collect can affect more than you.

A lock answers one question — who can open the app on this iPhone. It does not change what Scanner Vault PDF & OCR Scan sends to its developer; for that, see Scanner Vault PDF & OCR Scan's full privacy report.

What the lock does and does not do

It does

  • Ask for Face ID, Touch ID or passcode every time Scanner Vault PDF & OCR Scan opens
  • Hide message previews in notifications
  • Keep Scanner Vault PDF & OCR Scan's content out of Spotlight and Siri suggestions
  • With Hide, remove the icon from the Home Screen

It does not

  • Stop someone who knows your passcode
  • Encrypt or change how Scanner Vault PDF & OCR Scan stores data

Don't see Require Face ID?

  • If your iPhone is managed by work or school, the option may be restricted.

Other settings worth checking for Scanner Vault PDF & OCR Scan

    Settings › Privacy & Security › Photos. Limited Access lets you pick exactly which pictures the app can see; Add Photos Only lets it save without reading your library.

  3. Notifications

    Settings › Notifications › Scanner Vault PDF & OCR Scan › Show Previews: When Unlocked keeps message and account details off the Lock Screen.

FAQ

Does Scanner Vault PDF & OCR Scan have its own passcode?
Some apps offer an in-app PIN or biometric lock in their settings. The App Store privacy label does not say whether Scanner Vault PDF & OCR Scan does; the iOS 18 lock works regardless.
What happens to Scanner Vault PDF & OCR Scan's notifications when it is locked?
Locked and hidden apps do not show message previews or content in notifications, and their content does not appear in Spotlight search or Siri suggestions.
Can someone who knows my passcode open a locked app?
Yes. If Face ID fails, the lock falls back to your device passcode. Keep the passcode private if the lock matters to you.
Is a locked Scanner Vault PDF & OCR Scan encrypted?
The lock controls who can open the app on this iPhone. It does not change how the app stores or syncs data. Encryption depends on the developer and on your device passcode.
Why can't I see the Require Face ID option?
You need iOS 18 or later. Some Apple apps such as Settings, Calculator, Maps and Camera cannot be locked or hidden.
Does hiding Scanner Vault PDF & OCR Scan remove it from my purchase history?
No. Hidden apps still appear in App Store purchases and in Settings › Apps, and Screen Time reports still include them.
