How to Lock Secretly on iPhone

iOS 18 Face ID lock and Hidden folder · Secretly SIA · checked November 2026

Time needed
4 taps
Needs iOS 18 or later

Works for Secretly whether or not it has its own passcode. No download needed.

Short answer

Touch and hold Secretly's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Secretly 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 Secretly with Face ID

  1. Find Secretly 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. Secretly now asks for authentication every time it opens.

To test it, close Secretly from the App Switcher and open it again. You should see the Face ID prompt before any content appears.

Hide Secretly in App Library

  1. Touch and hold Secretly'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 Secretly?

Secretly's privacy label lists user content — the kind of data you would not want on screen if someone borrows your unlocked phone. Messengers see who you talk to as well as what you say. Even with end-to-end encrypted content, contact lists and metadata can be collected and linked to you.

Social apps are built around identity and contacts, so data linked to you is nearly universal. Tracking and contact upload are the settings worth checking.

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

What the lock does and does not do

It does

  • Ask for Face ID, Touch ID or passcode every time Secretly opens
  • Hide message previews in notifications
  • Keep Secretly'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 Secretly stores data
  • Sync to your iPad or other devices
  • Remove Secretly from purchase history or Screen Time reports

Don't see Require Face ID?

  • Update to iOS 18 or later in Settings › General › Software Update.
  • Make sure a passcode is set in Settings › Face ID & Passcode; the lock needs one.
  • Some Apple apps (Settings, Calculator, Camera, Maps, Find My, Clock) cannot be locked or hidden.
  • If your iPhone is managed by work or school, the option may be restricted.

Other settings worth checking for Secretly

  1. Tracking

    Settings › Privacy & Security › Tracking. If “Allow Apps to Request to Track” is off, apps cannot ask, and they are told to treat you as having declined. You can also turn it off for this app alone.

  2. Photos

    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. Contacts

    Settings › Privacy & Security › Contacts. Limited Access shares only the people you select instead of your whole address book.

  4. Microphone & camera

    Settings › Privacy & Security › Microphone and Camera. The orange and green dots in the status bar show when either is in use.

  5. Sign-in

    When creating an account, Sign in with Apple can give the app a relay address from Hide My Email instead of your real one.

FAQ

Does Secretly 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 Secretly does; the iOS 18 lock works regardless.
What happens to Secretly'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 Secretly 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 Secretly 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.
