7 iPhone Settings You Should Change Right Now for Better Privacy

Apple builds privacy into its devices by design, yet many iPhone owners don’t realize their default settings leave them more exposed than necessary. While Apple’s reputation for protecting user data is well-founded, several out-of-the-box configurations prioritize convenience or data collection over your personal security. By adjusting just a handful of settings, you can dramatically reduce how much information your phone shares without sacrificing functionality.

Limit the Diagnostic Data Apple Collects

Like any hardware manufacturer, Apple gathers diagnostic and usage information from every iPhone to understand how people interact with their devices and improve iOS performance. This data includes crash reports, feature performance metrics, and behavioral patterns. If you’re uncomfortable with your phone automatically transmitting this information to Apple’s servers, disabling it takes just a few taps.

Navigate to Settings, then Privacy & Security, then Analytics & Improvements. You’ll find three toggle options to adjust. Turn off Share iPhone Analytics to stop your device from sending usage data to Apple. While you’re there, disable Improve Siri & Dictation to prevent Apple from storing voice transcripts of your commands. Finally, switch off Share iCloud Analytics to keep your cloud activity more private. These changes won’t degrade your iPhone’s performance in any way.

Enable Mail Privacy Protection to Block Email Tracking

Many emails contain invisible tracking pixels that notify senders when and where you opened their message, a tactic used extensively by both marketers and spammers to gather behavioral data. Apple offers a built-in solution called Mail Privacy Protection that blocks these pixels and hides your location and IP address from email senders.

This feature works by loading email content through Apple’s servers rather than directly on your device. To activate it, open Settings, select Apps, then Mail, then Privacy Protection. Toggle on Protect Mail Activity. Keep in mind this only prevents pixel-based tracking; if you click a link inside an email, that action can still be tracked. When an email looks questionable, trust your instincts and avoid tapping links.

Hide Sensitive Content from Your Lock Screen

Your iPhone displays notifications, messages, and email previews on the lock screen by default, which means anyone glancing at your phone can read sensitive information. Notifications also cause your screen to light up with each alert, drawing attention from nearby people. Preventing this requires only one quick adjustment.

Go to Settings, then Notifications, then Show Previews. Select When Unlocked or Never so message content only appears when you’re actively using the device. If you prefer this privacy level for specific apps only, you can fine-tune notification settings individually for applications like WhatsApp or Messages instead of applying the change globally.

Turn On Automatic Updates for Security Patches

Apple regularly releases iOS updates that patch security vulnerabilities, squash bugs, and sometimes introduce enhanced privacy features without announcing them prominently. Third-party apps operate similarly, with many updates delivering quiet improvements that strengthen data protection. Missing these updates for days or weeks leaves your device exposed to known threats.

Enable automatic updates by going to Settings, then General, then Software Update, then Automatic Updates. Next, return to the main Settings screen, go to Apps, then App Store, then App Updates, and select On. This one-minute adjustment ensures your iPhone always runs the most recent secure and private versions of all your software.

Block App Tracking and Personalized Ads

Many apps track your behavior across other platforms to build detailed profiles and display eerily relevant advertising. Your iPhone gives you the power to shut down this tracking entirely. Start in Settings, then Privacy & Security, then Tracking. Look for Allow Apps to Request to Track; if it’s enabled, apps can ask permission to monitor your activity across third-party apps and websites. Turn this off to reject all such requests automatically.

While still in Privacy & Security, scroll down to Apple Advertising and disable Personalized Ads. Though Apple maintains it doesn’t track users like other companies do, this setting still limits how much of your activity gets used to personalize ads within Apple’s own applications.

Strengthen iCloud Backup Security with Advanced Data Protection

Backing up your iPhone data to iCloud offers incredible convenience, but it’s worth considering how secure that backup truly is and who might access it. Apple’s Advanced Data Protection applies end-to-end encryption to iCloud data, meaning only your trusted devices can decrypt and view the information. Apple itself cannot access the encrypted contents, even if legally compelled.

This feature isn’t activated by default. To enable it, go to Settings, tap your name, then iCloud, then Advanced Data Protection. You’ll set up a recovery method such as a recovery key or trusted contact to prevent permanent lockout if you forget your password.

Activate Two-Factor Authentication for Your Apple Account

Two-factor authentication provides a critical security layer for any account containing sensitive data. Your Apple Account connects to photos, messages, location history, payment information, and health records. If someone compromises your Apple Account, they can access everything connected to it.

Verify 2FA status by going to Settings, then your name, then Sign-In & Security, then Two-Factor Authentication. If it’s disabled, enable it immediately. With 2FA active, a six-digit code sent to a trusted device becomes required for login attempts, even if someone has your password.

Optimize Safari Privacy Settings and Choose a Privacy-Conscious Search Engine

Google pays Apple billions annually to remain the default iPhone search engine. If you’d rather not have every search tracked and converted into targeted ads, switching to a privacy-focused alternative takes moments.

Navigate to Settings, then Safari, then Search Engine, and select DuckDuckGo. This search engine doesn’t track queries or create behavioral profiles. While still in Safari settings, enable Prevent Cross-Site Tracking to stop websites from sharing your activity with other sites. Under Hide IP Address, select Trackers and Websites so both advertisers and websites cannot log your IP to fingerprint your device.

Audit App Permissions for Location, Camera, and Microphone

Apps require permission to access your location, photos, microphone, camera, and contacts. While some requests are legitimate, many apps ask for permissions they don’t genuinely need. Review these permissions regularly by going to Settings, then Privacy & Security, then tapping each category like Location Services, Microphone, or Photos.

You’ll see which apps have requested access and their current permission status. If you spot something odd, like a shopping app asking for microphone access, revoke it. Pay special attention to location permissions; most apps should have While Using the App rather than Always. Spending a few minutes reviewing these settings provides meaningful peace of mind about what data your apps can collect.
