Time needed
4 taps
Needs iOS 18 or later

Works for Life - Period Tracker Calendar whether or not it has its own passcode. No download needed.

Short answer

Touch and hold Life - Period Tracker Calendar's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Life - Period Tracker Calendar 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 Life - Period Tracker Calendar with Face ID

  1. Find Life - Period Tracker Calendar 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. Life - Period Tracker Calendar now asks for authentication every time it opens.

To test it, close Life - Period Tracker Calendar from the App Switcher and open it again. You should see the Face ID prompt before any content appears.

Hide Life - Period Tracker Calendar in App Library

  1. Touch and hold Life - Period Tracker Calendar'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 Life - Period Tracker Calendar?

Life - Period Tracker Calendar's privacy label lists location — the kind of data you would not want on screen if someone borrows your unlocked phone. Health trackers collect symptoms, vitals and habits. In the US, most consumer health apps are not covered by HIPAA, so the privacy policy is your main protection.

Health and fitness apps can read Apple Health data only for categories you approve, one by one. What they collect themselves is shown on the label.

A lock answers one question — who can open the app on this iPhone. It does not change what Life - Period Tracker Calendar sends to its developer; for that, see Life - Period Tracker Calendar's full privacy report.
