Works for Simple Transfer Pro whether or not it has its own passcode. No download needed.
Touch and hold Simple Transfer Pro's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Simple Transfer Pro 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 Simple Transfer Pro with Face ID
- Find Simple Transfer Pro on your Home Screen or in App Library.
- Touch and hold the icon until the quick-actions menu opens.
- Tap Require Face ID (or Require Touch ID / Require Passcode, depending on your iPhone).
- Tap Require Face ID again to confirm. Simple Transfer Pro now asks for authentication every time it opens.
To test it, close Simple Transfer Pro from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Simple Transfer Pro in App Library
- Touch and hold Simple Transfer Pro's icon and tap Require Face ID.
- Choose Hide and Require Face ID instead of Require Face ID.
- Confirm. The icon leaves your Home Screen and moves to the Hidden folder at the bottom of App Library.
- 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 Simple Transfer Pro?
Simple Transfer Pro is a photo backup app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Photo backup apps upload your library by design, including location metadata embedded in each picture.
Photo and video apps usually request access to your photo library. iOS lets you share only selected photos, which keeps the rest of the library — and its location metadata — away from the app.
A lock answers one question — who can open the app on this iPhone. It does not change what Simple Transfer Pro sends to its developer; for that, see Simple Transfer Pro's full privacy report.
