Time needed
4 taps
Needs iOS 18 or later

Works for Smart Cleaner - Pro Security whether or not it has its own passcode. No download needed.

Short answer

Touch and hold Smart Cleaner - Pro Security's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Smart Cleaner - Pro Security 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 Smart Cleaner - Pro Security with Face ID

  1. Find Smart Cleaner - Pro Security 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. Smart Cleaner - Pro Security now asks for authentication every time it opens.

To test it, close Smart Cleaner - Pro Security from the App Switcher and open it again. You should see the Face ID prompt before any content appears.

Hide Smart Cleaner - Pro Security in App Library

  1. Touch and hold Smart Cleaner - Pro Security'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 Smart Cleaner - Pro Security?

Smart Cleaner - Pro Security is a secure email app, the kind of app that tends to hold personal information you would not want on screen if someone borrows your unlocked phone. Email apps see every message and contact. Third-party mail clients may route mail through their own servers to offer features like push or AI summaries.

Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.

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

FAQ

Does Smart Cleaner - Pro Security 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 Smart Cleaner - Pro Security does; the iOS 18 lock works regardless.
What happens to Smart Cleaner - Pro Security'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 Smart Cleaner - Pro Security 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 Smart Cleaner - Pro Security 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.
