Keeping Your Location Private: How Your Apps Can Give You Away
Your Cape service protects you from those attempting to track you via the cell phone network. This protection is critical, but your apps and the permissions you give them can still share your location and other information with advertisers who sell that data. This guide explains how apps learn your location and what you can do to stop them.
How apps figure out where you are
- They ask, and we say yes. When an app asks to use your location and you tap “Allow,” it can see exactly where you are, sometimes all day, even when the app is closed. Weather, shopping, game, and social media apps often ask for far more than they need.
- They follow your phone’s “ad ID.” Every phone has a hidden ID number that advertisers use to tailor ads so you will be more likely to click them. Apps attach your location and activities to this number, and companies buy and sell those records. Anyone who buys them, including bad actors, can track the phone.
- They listen for Wi-Fi and Bluetooth. Even when you are not connected, your phone quietly calls out to nearby Wi-Fi networks and Bluetooth devices. Sensors in stores and on streets track your phone as it passes.
- They share what they collect. One app’s data rarely stays with that app. It flows to advertising companies that combine it with data from other apps to build a full picture of your daily routine.
Rules to Live By
- Be stingy with location. Only maps and a few trusted apps should ever get your location, and only “While Using the App,” never “Always.” Everything else gets “Never.”
- Say no to tracking. If an app asks to “track your activity,” always say no. In settings, choose the option that disables tracking so apps have nothing to attach your movements to.
- Turn off what you’re not using. Switch off Wi-Fi and Bluetooth when you leave home, and turn off Location Services completely if you don’t need directions. You can always turn them back on.
- Think before you install. Free apps make their money by selling your location. If you don’t know and trust the company, don’t install the app.
- Ignore calls, messages, and links from strangers. Malicious actors often try to trick you into providing personal information or installing trackers on your phone.
- Keep the phone updated and power it off and on again daily. Updates fix the holes that eavesdroppers use to sneak in. A daily restart clears out many kinds of malicious software.
