If private information appears while your iPhone is locked, first check the app tied to the suggestion: open Settings > Siri (or Apple Intelligence & Siri) > Apps, select the app, and turn off its available suggestion controls. If what you saw was notification text, change Settings > Notifications > Show Previews instead. These are separate settings, so you may need to adjust both.
First identify what appeared
The right fix depends on whether the Lock Screen showed an app or action suggestion, the contents of a notification, or another feature available while locked. Apple’s settings differ by app and software version; the labels below may not appear exactly the same on every iPhone.
- An app or action suggestion: adjust that app’s Siri suggestion controls.
- Message, Mail, or Calendar details: adjust notification previews.
- Information available through another Lock Screen feature: review what is allowed while locked.
Turn off Siri suggestions for the app involved
For an app-derived suggestion, per-app controls are the most targeted place to start. Apple says Siri Suggestions are on by default and can be changed separately for each app. [Apple Support: Change Siri settings]

- Tap Siri or Apple Intelligence & Siri, depending on your software version.
- Tap Apps, then choose the app connected to the information.
- Turn off the suggestion-related switches available for that app. The exact options vary, so review the controls shown on your device.
This changes suggestions associated with that app; it does not necessarily hide text in its notifications. If private notification content is also visible, adjust previews separately.

Hide notification details on the Lock Screen

- Open Settings > Notifications > Show Previews.
- Choose When Unlocked to show details only after the iPhone is unlocked, or Never to suppress previews.

Lock a sensitive app when your iPhone supports it
App locking adds another layer for supported apps. Touch and hold the app icon, choose Require Face ID (or Touch ID or passcode, if offered), then authenticate. The option is not available for every app or every iOS version, so use it only if it appears in the app’s menu.

Review other Lock Screen access
If the information is still reachable through a Lock Screen feature, review Settings > Face ID & Passcode (or Touch ID & Passcode) > Allow Access When Locked. Turn off features you do not want available before unlocking. This can reduce at-a-glance access and convenience for you as well as for someone holding the phone. [Apple Support: Set a passcode on iPhone]
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Check location-based suggestions separately
If the suggestion appears tied to your location, Apple documents a separate control at Settings > Privacy & Security > Location Services > System Services > Suggestions & Search.
