Your iPhone ships with dozens of settings that quietly expose your location, behavior, and identity to apps, advertisers, and Apple itself. Here are five you should change today.
1. Location Services Set to Always
Go to Settings, then Privacy and Security, then Location Services. You will likely find multiple apps set to Always. This means they track your exact GPS coordinates around the clock even when you are not actively using them. Change every app to Never or While Using the App. The only exceptions should be navigation apps you actively choose to use.
2. Cross-App Tracking Enabled
Go to Settings, then Privacy and Security, then Tracking. Toggle off Allow Apps to Request to Track. This setting controls whether advertisers can follow you from app to app using your unique device identifier. With it on, every ad network you encounter can build a behavioral profile tied to your device.
3. Sharing Data With App Developers
Inside Safari, under Privacy and Security, there is an option called Share With App Developers. When enabled, this sends your browsing crashes and behavior data directly to developers. Turn it off unless you have a specific reason to keep it on.
4. Siri and Dictation Sending Audio
Go to Settings, then Siri and Search, then Siri and Dictation History. You can delete your Siri history from Apple servers here. Additionally, under Settings, Privacy and Security, Analytics and Improvements, turn off Improve Siri and Dictation. This stops your voice recordings from being used to train Apple AI models.
5. Personalized Ads From Apple
Go to Settings, then Privacy and Security, then Apple Advertising, then toggle off Personalized Ads. This stops Apple from using your app usage, purchases, and search behavior to target ads at you in the App Store and Apple News. It does not reduce the number of ads you see, only whether they are targeted.
There are 22 more settings like these.
