How to prevent your smartphone apps from being tracked by others.

by James · March 9, 2023

Imagine if a data broker knows your phone is on the nightstand next to another phone six nights a week and on the town on the seventh night. This data broker also knows where you are going and how long you are there. Creepy.

Do you want a shock? If you have an iPhone, hidden deep within the settings is a feature Apple calls “Notable Places.” Click here to find the exact steps to view your personal map.

The question may arise: “How is this tracking done?” You allowed it. Install an app, and the legalese says that the app developer has the right to share or transmit data collected from users to third parties, including advertisers, marketers or data brokers.

A snooping partner, stalker, or family member may be tracking your location. I’ll help you stop it.

Your place is worth a lot

Apps can use location tracking in a number of ways.

• Location-based services: Many apps use location tracking for GPS navigation, weather updates, local news, or finding nearby restaurants or shops.

• Advertising: Have you ever driven by a Starbucks or Duncan Donuts and received a $5 coupon on your phone? An app may use your location to show you offers from nearby businesses or services.

• Analytics: Application developers collect data to understand how users move around a physical area or to identify trends and patterns.

Some apps offer the option to limit or completely turn off location tracking. These settings are easy to fiddle with, but you need to be thorough. You may have already turned off location tracking on your phone, but you haven’t done the same on your laptop. Knocks off the target.

I’ll walk you through how to change your device and account settings with a number of major players.

Start with Google

Your Google Account is tied to various apps and services, so let’s start there.

Location history

As the name suggests, Location History saves your location wherever you take your phone. It’s off by default, but you might have turned it on and forgotten. No problem. To turn it off:

• Sign in to your account at myaccount.google.com or through the Google app.

• Go Data protection > Location history.

• Tap or click Turn off and confirm your choice.

• While you’re here, make sure Auto Delete is turned on Next.

One last super important thing: open it Tools in this account to see a list of devices that save your location. Select Turn Off to block any devices you don’t want to track you on.

Do you suspect there is a stalker in your life? These are the steps to get them to spy on your texts.

Location sharing

Location Sharing allows you to share your location with the people you choose from your devices. Your loved ones may be using this setting, but it’s worth checking.

• Sign in to your account at myaccount.google.com or through the Google app.

• Go Data protection > Location sharing.

• If you don’t share your location with anyone, there’s nothing to do here.

• People with whom you share your location appear here.

• Tap or click Stop next to the name of anyone you want to stop sharing your location with.

Location tracking on iPhone

Location Services has two parts: A global setting that stops your location from being shared with Apple, and individual settings for apps installed on your iPhone.

Let’s review the service controls:

• Go Settings > Privacy and security > Location services.

• From here you have the option to switch Who Location services in full.

• Alternatively, you can turn off Location Services for individual apps by scrolling down the list and tapping the apps you want to change.

Location sharing

Location Sharing lets you share your location with family and friends in Messages, Find My, and other services.

• Go Settings > Privacy and security > Location services > Share your position.

• If you share your location with anyone, you can see their name here.

• Switch Who Share your position at any time.

Cookies aren’t just used on your computer to track your passwords, shopping carts, and everything else. They’re there on your phone, too. You can delete them.

Location tracking on your Android phone

Choose to turn off location tracking entirely or fine-tune settings for individual apps.

• Go Settings > Location and switch Who Use the Location option.

• If you leave the setting on, scroll down and change the settings for each app by tapping on them.

Location sharing on Google Maps

You may have shared your location with friends and family through Google Maps. Here’s how you can check if you’re doing it without realizing it.

• Tap the Location sharing. Not sharing your location with anyone? There is nothing more to do.

Speaking of privacy, I wrote about a buried Google Maps setting that you should change now.

• Go Start > Settings > Private life > Location.

• Turning off Location on this device also prevents apps from knowing your location.

• When Allow apps to access your location is turned on, scroll down and turn off the setting for each app.
