Much of this is possible because people use apps that reveal their location to data brokers, who package the information and resell it to companies like Babel Street. Apple does have an advantage here—Atlas estimated they could locate roughly 80% of Android phones but only 25% of iPhones. That’s due to Apple’s App Tracking Transparency feature, introduced in iOS 14.5, which requires apps to get permission from users before tracking them for third-party advertising purposes. Unfortunately, many people unthinkingly grant such permissions, and location and identification data can also leak out in other ways.

Although it’s difficult to avoid being tracked by data brokers entirely, you can drastically reduce the likelihood and frequency of tracking, which helps ensure that any location information that does become available isn’t sufficient to identify you personally. Your employer may also consider your location to be sensitive information and want you to restrict it to the extent possible. To achieve this, you’ll need to adjust settings in several parts of Settings > Privacy & Security on your iPhone (and iPad, if you regularly use it in multiple locations).

Turn Off Allow Apps to Request to Track

You’ll find the most important setting in Settings > Privacy & Security > Tracking. At the top of the screen is a switch labeled Allow Apps to Request to Track. Make sure that is off! If it has been on in the past, apps that have requested permission will appear below.

By preventing apps from even asking if they can track you, you keep them from sharing a unique identifier associated with your iPhone with other apps and websites. Otherwise, advertisers can follow you from app to app and website to website, gathering information about you—often including your physical location—as you go about your life.

Don’t let apps persuade you to turn this setting on or allow them to track you. Apple’s rules explicitly forbid them from reducing functionality to those who refuse to allow tracking.

Allow Location Access Only for Apps That Need It

While you can turn off Allow Apps to Request to Track with a single switch, preventing apps from seeing your location requires more targeted work. Although Settings > Privacy & Security > Location Services has a big Location Services switch, turning that off will drastically reduce the utility of your iPhone. You won’t be able to get directions from Maps, tag photos with their location, share your location with family members, and much more.

Instead, for each app in the list, determine what level of location access you want to grant based on its function and description of why it needs access. Grant the minimal level of access necessary, which varies by app. Navigation apps need location access to work at all. Camera apps need it to geotag photos. Weather apps use it to provide custom weather reports and extreme weather notifications. But do you want to give a social media app access to your location at all times?

Apple provides five location access levels:

• Never: Choose Never for any app with questionable explanations of why location access is requested.
• Ask Next Time or When I Share: If you’re unsure if you want to allow or deny location access for an app, select this option. The app will prompt you the next time it wants your location, enabling you to make an informed decision based on your actions.
• While Using the App: For most apps you want to allow to see your location, choose While Using the App. It’s entirely reasonable that a location-requiring app be allowed to determine your location while you’re using it.
• While Using the App or Widgets: This option only appears for apps with widgets; choose it only if you use a widget that needs location access.
• Always: Grant Always access only to apps that generate location-related notifications when the app is not open. The most common example is a weather app that provides notifications of incoming storms.

The Precise Location option becomes available if you allow location access for an app. Turn it on only if the app needs to know your location within 15 to 200 feet (5 to 60 meters). An Uber or Lyft driver will need to know where to pick you up, for instance, so those apps should have Precise Location turned on, as should navigation and camera apps. For most others, turn off Precise Location. Your approximate location—a variable radius between 2.5 to 12 miles (4 and 20 kilometers)—is usually sufficient to locate you in the right part of the world.

Block Bluetooth and Local Network Access for Apps That Don’t Need It

Apps can use Bluetooth to infer your general location through interactions with other Bluetooth devices and movement patterns, so Apple requires apps to ask to use Bluetooth. As a result, just as with location, you should go through the apps listed in Settings > Privacy & Security > Bluetooth and revoke permission from any that don’t seem as though they should need it. Most will be legitimate—an app designed to communicate with a Bluetooth-connected device, for instance. Any app that needs access to Bluetooth and doesn’t have it should prompt you when you next open it.

Similarly, Apple now requires apps to request permission to use your local network. For the most part, these requests are reasonable—apps may need to discover network-connected devices like routers, printers, speakers, smart home gadgets, and more. Or games may need to discover other players on the network. However, because your network can reveal information about your location, it’s best to revoke access for any apps that don’t seem as though they should need it. There’s no harm in doing so; they’ll ask again if they need access.

Ultimately, all we can do is stay vigilant about what we’re allowing on our devices, encourage Apple to add even more privacy protections, and lobby our elected representatives for legal protection. It’s unconscionable that private companies can gather extensive location data on hundreds of millions of citizens.

The key to the system is Apple’s Find My network of hundreds of millions of Apple devices, which detect nearby AirTags and report their location to Apple’s servers. It’s all completely private and secure, so only the owner of an AirTag can see where it is. All the devices in the Find My network are anonymous, and location data is encrypted at every step of the way. Not even Apple can locate an AirTag or determine the identity of the device that helps find it.

Plus, if you have an iPhone 11 or iPhone 12 with support for Ultra Wideband, the Find My app can use Precision Finding to give you the direction and distance of your nearby items. (“You’re getting warmer!”) If you need more help to locate an AirTag that’s out of sight, you can make it play a sound.

At $29 for one or $99 for a pack of four, AirTags are an inexpensive way to keep track of keys, purses, suitcases, kids’ backpacks, and more. You could even attach one to your dog’s collar, but it would likely be helpful only in urban areas where people with iPhones would come close enough to your rambling pet.

With great power comes great responsibility, though. There are always those who will attempt to use AirTags to track other people’s movements surreptitiously, perhaps a jealous spouse, a vindictive ex, or someone with a creepy crush. It wouldn’t be hard to hide an AirTag in someone’s car, in a seldom-used purse pocket, or in the lining of a coat.

Apple is fully aware of these possibilities and has built three safeguards into the AirTags and the Find My network. Given the potential for abuse, it’s essential that everyone knows what an AirTag is (done!) and how to determine if someone may be using one to track another person (read on!).

• Safety Alerts: If you get an “AirTag Found Moving With You” alert on your iPhone, you know that there’s an AirTag separated from its owner that’s traveling with you. Most likely, it’s in something you’re borrowing or attached to an item that someone left in your car. If you can’t easily find the AirTag, you may be able to make it play a sound. (That won’t work if the owner is in range or if it has been with you overnight such that its identifier has changed since the alert.) If you know why it’s there, you can pause the safety alerts for a day or disable them permanently for those in your Family Sharing group. If the owner has marked it as lost, you can tap Learn About This AirTag to discover its serial number and contact information for the owner. If there’s no good explanation for why the AirTag is with you, you can remove its battery to prevent it from reporting your location.
  
• Safety Sounds: If an AirTag is separated from its owner for 3 days, it will make a sound the next time it moves. There is some concern that 3 days may be too long and that the sound starts only after the AirTag moves. Apple has said it may change the time or tweak the system if the sound isn’t achieving its goal of tattling on maliciously placed AirTags.
• NFC identification: Let’s say you find an AirTag after a safety alert or sound. Hold an iPhone or other NFC-capable smartphone to the white side of the AirTag and tap the notification to load a website with the AirTag’s serial number and the last four digits of the owner’s phone number (which may help you or the police identify them). If the owner has marked it as lost, you’ll also see their phone number or email address.

The safety alerts appear only on iPhones, of course, but there are two other requirements that must be true as well. First, the iPhone must be running iOS 14.5 or later to display the alerts, so make sure you update. Second, in Settings > YourName > Find My > Find My iPhone, the Find My network option must be enabled. If you don’t want your iPhone to participate in the Find My network, you can turn that option off, but doing so means you’ll never receive a safety alert either.

(A quick aside: the Find My iPhone option in that screen is necessary to locate your iPhone if it’s lost or stolen. It also enables Activation Lock, which prevents a thief from erasing and reactivating your iPhone unless they can find your Apple ID password. Always leave Find My iPhone enabled. The Find My network can also help locate iPhones, iPads, Macs, and Apple Watches that are offline and can’t report their location to Find My on their own.)

The ultimate takeaway is that if you ever get a safety alert, hear an AirTag making a sound, or find an unexpected AirTag, hold your iPhone or an NFC-capable Android phone to the white side of the AirTag to load a Web page with more information. If you have reason to believe you’re being stalked, contact local law enforcement and give them the AirTag’s serial number, which they can use, with Apple’s help, to identify the AirTag’s owner.
