Location tracking is a double-edged sword. While it can be helpful to keep tabs on friends and family, it's a privacy nightmare when your phone carrier is involved. Many major phone carriers have already been fined by the FCC for selling location data, so it's crucial to take extra steps to secure your privacy. If you have an iPhone, iOS 26.3 introduced a precise location feature that puts some space between you and your carrier. Here's how to check who has access to your location data and customize your settings, but remember, it's not just about the apps you use; it's also about the backend location-tracking features within iOS System Services.
Managing Location Tracking on Your iPhone
To manage who has access to your location data, go to Settings > Privacy & Security > Location Services, and choose the app you want to manage. Since iOS 14, there have been four options:
- Never: Ensures that location services will never be tracked while using this app.
- Ask Next Time or When I Share: Asks how you want to proceed each time you open the app: Allow once, Allow while using, or Don't allow.
- While Using the App: Tells the app to only utilize location tracking while it is actively in use on the screen, either in the app or via the on-screen widgets that iOS now supports. Some apps, such as Google Maps and Apple Maps, will also have While Using the App or Widgets as an option.
- Always: Permits the app to always track an iOS device's location, even when the app is not actively being used. Not all apps will have this option available.
If you want to know which apps have been requesting location data the most, look for the arrow icon next to its entry. A purple arrow means the app has used your location recently, while a gray arrow says that your data has been accessed in the last 24 hours. Depending on how often you use a specific app, this icon can help you determine if you need to rein in its data requests.
Controlling Access to Precise Location
If you're okay with apps using location data but feel uneasy about them knowing exactly where you are, turn off Precise Location, and the app will only know your approximate location. This should be sufficient for most apps and services, but you might want to leave it on for things like Uber or Google Maps, where an exact location is needed.
New in iOS 26.3 is Limit Precise Location, which restricts how much information is shared with your cellular provider. "With this setting turned on, some information made available to cellular networks is limited," Apple says. "As a result, they might be able to determine only a less precise location—for example, the neighborhood where your device is located, rather than a more precise location (such as a street address)." Apple says this won't affect signal quality, sharing your location with first responders, or tracking on apps like Find My. However, it's currently limited to devices that have Apple's C1 or C1X modem, which include the iPhone Air, iPhone 16e, and the cellular version of the iPad Pro M5. It also requires carrier support, which only includes Boost Mobile in the US right now.
Disabling Backend Location-Tracking Features
You can also disable certain backend location-tracking features within iOS System Services. Go to Settings > Privacy & Security > Location Services, scroll to the bottom of the list, and select System Services. You're presented with a list of items you can toggle on and off. Here's how they use location tracking:
- Apple Pay Merchant Identification: Uses your current location to help provide more accurate merchant names when you use your physical AppleCard.
- Cell Network Search: Tracks cell tower usage and sends data to Apple.
- Compass Calibration: Uses location tracking to help calibrate the electronic compass.
- Device Management: Allows you to wirelessly configure devices, like an app for gig workers or a VPN for a school or business.
- Emergency Calls & SOS: Allows users to discreetly call 911 and uses location data to help assist in the event of an emergency.
- Find My iPhone: A service provided by Apple that will enable you to track an iOS device remotely.
- HomeKit: Helps make smart homes smarter by using location tracking to do things like opening your garage door or turning on lights automatically.
- Location-Based Alerts: Permits Apple to use your location to give geographically related alerts or news, like Amber Alerts or severe weather warnings.
- Motion Calibration & Distance: Used by fitness or activity apps to track activity accurately.
- Networking & Wireless: Tracks Wi-Fi usage and sends data to Apple.
- Setting Time Zone: Uses location tracking to automatically adjust the time when changing time zones.
- Share My Location: Lets you share your current location with individuals through iMessage or other apps like Find My.
- Suggestions & Search: Enable location-specific suggestions for Safari and Spotlight.
- System Customization: Changes system appearance, behaviors, and settings using location data.
- Significant Locations: Tracks and remembers the places that you are at most often and sends alerts based on calendar events or map directions.
- iPhone Analytics: Helps Apple by occasionally providing the company with information about how a specific iOS device is used.
- Routing & Traffic: Shares current traffic patterns and speed with Apple to improve Maps.
- Improve Maps: Allows Apple to use current location to alert iOS users to the estimated time to get to their frequent locations.
Many of the items on this list are safe to disable. Features like Cell Network Search and Networking & Wireless are not necessary for everyday usage. Others, like HomeKit or Motion Calibration & Distance, are only useful if you use home automation or fitness tracking. If you don't want to share unnecessary data with Apple, you can disable iPhone Analytics.
If you're worried about when your phone is using location data, turn on Status Bar Icon under System Services. This will show a black arrow icon in the status bar any time system services access your location.
In my opinion, the key to managing location tracking on your iPhone is to be aware of the options available and to customize them to your needs. While it's important to protect your privacy, it's also important to consider the trade-offs. For example, turning off Precise Location might be sufficient for most apps, but it might not be for services like Uber or Google Maps, where an exact location is needed. It's up to you to decide what's right for you.
