Location tracking works through several different technologies built into your phone. GPS (Global Positioning System) is the most well-known method. Your phone receives signals from satellites orbiting Earth, typically at least four satellites, to calculate your exact position. GPS is highly accurate—often within 5 to 10 meters in ideal conditions, though this can vary based on weather, tall buildings, and other obstacles.

Beyond GPS, your phone also uses cellular network data to determine location. Your device constantly connects to nearby cell towers, and companies can estimate your position based on which towers your phone communicates with. This method is less precise than GPS but works indoors and uses less battery power. A third method involves Wi-Fi positioning. Your phone scans nearby Wi-Fi networks and compares them to databases of known network locations to estimate where you are.
According to a 2023 Pew Research Center survey, approximately 72% of American smartphone users had location services enabled on their devices. Your phone combines data from all these sources—GPS, cellular signals, and Wi-Fi networks—to provide the most accurate location possible at any given moment. This process happens continuously in the background whenever your phone is powered on.
Different apps and services use location data for various purposes. Navigation apps like Google Maps and Apple Maps use GPS to provide turn-by-turn directions. Weather apps use your location to show local forecasts. Social media apps may use location to tag where photos were taken. Ride-sharing services like Uber and Lyft use real-time location to match drivers with passengers.
Practical takeaway: Understanding how location tracking works is the foundation for making informed choices about when to use these features and when to disable them. Recognize that multiple technologies work together to pinpoint your location, and each can be managed separately through your phone's settings.
Finding your location settings differs slightly between iPhone and Android devices, but both operating systems make this information reasonably straightforward to locate. On an iPhone running iOS 16 or later, open the Settings app, tap "Privacy," then select "Location Services." You'll see a toggle at the top to turn location services on or off. Below that, you'll see a list of every app installed on your phone with three options next to each: "Never," "Ask Next Time," or "Always."

On Android devices running version 12 or later, the process is similar. Open Settings, then navigate to "Location" or "Privacy" (the exact path varies by phone manufacturer). Look for "Location Services" or "Location" and tap it. You'll see a toggle to enable or disable location services entirely. Scrolling down will show individual app permissions. Android displays icons next to app names—a solid arrow means the app always has location access, while a hollow arrow means it can request access.
A useful feature on both platforms is the ability to see which apps have recently used your location. On iPhone, look for small arrow icons next to app names in the Location Services list—a purple arrow means the app used location in the last 24 hours, while a purple outlined arrow means it used location in the last few days. On Android, many phones show a location access history in the Privacy settings, detailing which apps requested location data and when.
You can also check what location data third-party services have collected about you. Both Google and Apple allow users to view their location history. To check your Google location history, visit myactivity.google.com and filter by "Location." Apple users can check their location history through the Maps app by viewing their frequent locations in the sidebar.
Practical takeaway: Regularly reviewing your location settings takes just a few minutes and provides valuable insight into which apps are tracking you. Many people discover apps they forgot they had installed and adjust permissions accordingly. Make this a monthly habit to stay informed about what data is being collected.
Most smartphone apps request permission to access your location when you first open them, though you may have missed or dismissed these requests. Rather than granting permission to every app that asks, you can be selective about which apps truly need access to your location data. Consider the app's primary function: a weather app genuinely needs your location to provide accurate forecasts, while a note-taking app typically has no legitimate reason to track where you are.

On iPhone, you have four permission options for each app. "Never" prevents the app from accessing your location entirely. "Ask Next Time" means the app will request permission each time it needs location data, allowing you to decide in the moment. "While Using" allows location access only when the app is actively open on your screen. "Always" permits location access even when the app is running in the background. For most apps, "While Using" provides a reasonable balance between utility and privacy.
Android offers similar controls with slightly different labels. "Don't allow" blocks location access. "Allow only while using the app" restricts access to active use. "Allow all the time" permits background access. On newer Android versions, you can also choose "Allow only this time," which grants a single permission that expires after one use. This setting is particularly useful when you want to share your location momentarily but don't want ongoing access.
Some apps request "approximate" rather than "precise" location. Approximate location provides information at a neighborhood or city level—accurate to within about 3 kilometers—without revealing your exact coordinates. This option provides enough information for many apps to function properly while protecting more detailed location data. If an app offers this choice, granting approximate location access instead of precise access reduces privacy risk with minimal functional loss.
Practical takeaway: Review your app permissions quarterly and remove location access from apps that don't require it for their core functions. Keep a mental note of which apps legitimately need location data versus which ones request it for tracking purposes like targeted advertising. Most users can safely revoke location permissions from at least half their installed apps.
The most direct way to prevent location tracking is to disable location services entirely when you're not using navigation, maps, or other location-dependent services. On iPhone, you can quickly toggle location services off through Control Center. Swipe down from the top-right corner (on newer models) or up from the bottom (on older models), then long-press the location icon and select "Turn Off." This disables all location services system-wide until you re-enable them.

Android users can access a similar toggle through Quick Settings. Swipe down twice from the top of the screen to open Quick Settings fully, then locate and tap the "Location" icon. This disables all location services. Some Android phones also allow you to toggle between "High Accuracy" mode (which uses GPS, cellular, and Wi-Fi) and "Battery Saving" mode (which uses only cellular and Wi-Fi signals). If you need location services but want to reduce battery drain and data collection, Battery Saving mode provides a middle ground.
Beyond system-wide toggles, you can disable location for specific services. On iPhone, go to Settings > Privacy > Location Services and scroll to the bottom. You'll find toggles for system services like "Significant Locations," "Location-Based Suggestions," and "Sharing My Location." Disabling these prevents your phone from recording where you spend time and from sharing location data with other Apple services.
Android provides similar granular controls in the Location settings menu. Look for options labeled "Location Services" or "Location Accuracy." You can disable Google Location Accuracy, which helps Google Maps provide better directions but also allows Google to collect location data. You can also disable emergency location service sharing, though note that emergency services can still locate you through your cellular connection if you call 911.
Practical takeaway: Develop a habit of disabling location services when you leave your home for non-navigation purposes. If you're going to a retail store, restaurant, or social event where you don't need directions, turn off location services and re-enable them when you need navigation again. This simple practice significantly reduces the amount of location data collected about your daily movements.
Beyond the apps on your phone, major technology companies collect location data through various means. Google collects location information from Android devices, Google Maps usage, and through its advertising network. According to Google's own transparency reports, the company receives location queries billions of times per day. This data helps Google provide services like predictive traffic conditions, but it also enables targeted advertising based on where you've been.
