Works for Daily Life Diary whether or not it has its own passcode. No download needed.
Touch and hold Daily Life Diary's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Daily Life Diary 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 Daily Life Diary with Face ID
- Find Daily Life Diary 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. Daily Life Diary now asks for authentication every time it opens.
To test it, close Daily Life Diary from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Daily Life Diary in App Library
- Touch and hold Daily Life Diary'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 Daily Life Diary?
Daily Life Diary is a journal & diary app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Journals collect your private thoughts, moods and often your location and photos. A lock screen inside the app is not the same as encryption of the synced entries.
Lifestyle apps cover family, home and personal organisation, and often combine location, contacts and photos in one place.
A lock answers one question — who can open the app on this iPhone. It does not change what Daily Life Diary sends to its developer; for that, see Daily Life Diary's full privacy report.
