Works for Sync.me whether or not it has its own passcode. No download needed.
Touch and hold Sync.me's icon, tap Require Face ID, then confirm. On iOS 18 and later that puts Sync.me 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 Sync.me with Face ID
- Find Sync.me 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. Sync.me now asks for authentication every time it opens.
To test it, close Sync.me from the App Switcher and open it again. You should see the Face ID prompt before any content appears.
Hide Sync.me in App Library
- Touch and hold Sync.me'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 Sync.me?
Sync.me's privacy label lists contacts and user content — the kind of data you would not want on screen if someone borrows your unlocked phone. Contacts backup apps upload your whole address book — other people's names, numbers and addresses, not just yours.
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 Sync.me sends to its developer; for that, see Sync.me's full privacy report.
What the lock does and does not do
It does
- Ask for Face ID, Touch ID or passcode every time Sync.me opens
- Hide message previews in notifications
- Keep Sync.me'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 Sync.me stores data
- Sync to your iPad or other devices
- Remove Sync.me 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 Sync.me
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.
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.
Contacts
Settings › Privacy & Security › Contacts. Limited Access shares only the people you select instead of your whole address book.
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.
Notifications
Settings › Notifications › Sync.me › Show Previews: When Unlocked keeps message and account details off the Lock Screen.
