Apple’s iPhone includes privacy and security features that can help protect personal data if a phone is lost, stolen or handled by someone else. The article outlines five settings users can review, including controls for what is accessible from the Lock Screen, app permissions and access to selected apps.

Notifications can be set to show previews only when the phone is unlocked, and Lock Screen access to tools such as Control Centre and Siri can be restricted. Safety Check lets users review sharing and app permissions; location access can be limited to when an app is in use, with precise location disabled where appropriate. App Privacy Report tracks access to sensitive data, while apps can be locked or hidden using features available in iOS 18; the article also points to Find My, Safari privacy controls and Lockdown Mode.
