Want to Lock Down Your iPhone? Here Are the Settings to Change

Apple’s iPhone is known for its robust privacy features, offering users more control over their personal data than many other devices. However, many of these privacy settings are not enabled by default, meaning that to maximize your privacy, you need to actively adjust them. With the release of iOS 26, which accompanies the iPhone 17, users have access to a comprehensive suite of privacy options that can help you lock down your data, control app permissions, and secure your device. While these settings provide significant protection, it is essential to understand that no device connected to the internet can guarantee complete anonymity.

### Managing App Tracking and Location Services

One of the most common privacy concerns is app tracking—when apps follow your activity across other apps and websites to build a profile for targeted advertising. iPhones allow you to deny any app’s request to track you entirely. To do this, open the Settings app, scroll to Privacy & Security, and select Tracking. Here, you can disable “Allow Apps to Request to Track,” which automatically blocks all new tracking requests. You can also review and revoke tracking permissions previously granted to apps.

Location sharing is another area where privacy can be tightened. Some apps genuinely need location access, like navigation apps, but others might request it unnecessarily. Within Privacy & Security, under Location Services, you can see which apps have location access and adjust their permissions individually. For apps that don’t require precise GPS data, you can turn off Precise Location, limiting the app to approximate location information. Additionally, under System Services within Location Services, you can disable settings that contribute to location tracking without affecting essential functions—for example, turning off Product Improvement and Significant Locations & Routes settings can limit how much your iPhone tracks your movements, like your home address or commute routes.

### Controlling App Sharing and Data Permissions

Apps often share information with each other, which can sometimes lead to unnecessary data exposure. In the Privacy & Security menu, you’ll find a list of apps and the permissions they have to share data. For instance, the Photos app may be fully shared with Google Drive by default, but if you don’t use Google Drive for photo backups, you can restrict the access to limited or block it outright. This prevents metadata like the date or location of your photos from being shared unnecessarily.

### Turning Off Analytics and Personalized Advertising

By default, iPhones collect some analytics data to help Apple improve its products, and personalized ads are enabled. To enhance privacy, scroll to the bottom of the Privacy & Security section to find Analytics & Improvements and Apple Advertising. Disabling “Share iPhone Analytics” and “Share With App Developers” stops your device from sending usage data to Apple and app developers. Turning off Personalized Ads means that the ads you see won’t be targeted based on your activity but will be generic instead. Apple’s advertising system still protects privacy better than many other platforms by blocking cross-site tracking, but disabling personalized ads adds an extra layer of privacy.

### Exploring Privacy Reporting Tools

iOS 26 introduces privacy reporting tools that give you insight into how apps use your data. The App Privacy Report shows which domains an app contacts, giving you visibility into its network activity. The Apple Intelligence Report reveals requests made through Apple’s on-device intelligence features. These reports are technical and don’t directly enhance privacy but serve as valuable tools for users who want to understand what their apps are doing behind the scenes.

### Securing Your Notes and Hiding Sensitive Content

Apple automatically synchronizes your Notes app via iCloud, which means your notes are stored on Apple’s servers. If you prefer to keep your notes completely private and local to your device, you can enable the “On My iPhone” account in the Notes app settings. This prevents your notes from syncing across devices. Additionally, you can secure sensitive notes by setting a password or encrypting them, though this means those notes won’t be accessible on other Apple devices and could be lost if your phone is lost without a backup.

You can also hide apps and photos to protect your privacy. By holding down an app icon and selecting “Edit Home Screen,” you can hide apps from your home screen while keeping them installed on your device. You can also require Face ID to open specific apps, adding a biometric layer of security. Photos have a “Hidden” album that is locked behind Face ID or a password, allowing you to hide sensitive images from casual viewers.
