It’s just that: They’re always listening. Nearly all voice-activated technology uses microphones that listen for “wake words.” It also means companies like Apple, Facebook and Google hear all your commands and can pick up conversations if your device thinks it hears the wake word. And these devices are accidentally activated far more often than you might feel. We don’t blame you if you’re uncomfortable with how much your smart devices can hear in your home. Your smartphone alone contains cameras, a microphone and plenty of other tools that can be misused against you. If you want to take control of your privacy and keep conversations “behind closed doors,” here’s how to stop your smart devices from listening.

Blocking stalkerware

A common way your devices can spy on you has nothing to do with the companies who made them. Instead, this method involves tampering with your tech so it can spy on what you do and say. It’s called “stalkerware,” and if one of these dangerous apps is installed on your computer or smartphone, the person behind it may already know quite a bit about you. Stalkerware apps are often marketed for “parental control” purposes, but these apps can be abused in the wrong hands. They generally collect your web browsing history, text messages and phone calls. Some can even capture what you’re doing on-screen. So how can you spot them? A surge in data usage, odd charges on your bill and other red flags are clues that something is wrong. Tap or click to see the top 6 signs and what you can do.

Foiling Facebook

Facebook sometimes requests access to the microphone for video chatting and text-to-speech purposes. But if you’re uncomfortable giving Facebook control of your mic, here’s how you can stop it.

Stopping voice assistants

Untangling ultrasonic technology

Are you familiar with ultrasonic tech? Most people aren’t, but your smart devices are aware of it. “Ultrasonic” refers to radio waves that humans can’t hear. They’re perfect for stealthily issuing commands to smart devices. Why would anyone want to collect these inaudible sounds? It comes down to money. Apps that use ultrasonic tech are constantly looking for “beacons,” which are audio clues that suggest where you shop and what you like to buy. These apps then pair browser cookies to your device to track you. Thankfully, in 2017, Google announced that 234 Android apps using ultrasonic tracking would be banned or suspended. In 2021, the company banned cross-platform tracking as part of its ad policy. But if you’re still unsure whether an Android or iOS app uses ultrasonic tech for other reasons, you can always disable the microphone using the exact steps you used for Facebook.

For iOS

Open the Settings app. Then, scroll down and tap Privacy & Security.Locate the menu labeled Microphone and tap it. Find the app you want to turn the mic off for in the list of apps and toggle the green switch to the off position.

For Android

Open the Settings app. Then, scroll down and tap Personal.Tap Privacy and safety, followed by App Permissions.Tap Microphone and locate the app you want to turn the mic off for.Toggle the slider to the off position.

With your devices no longer listening, you can relax and feel less paranoid about using your tech. And the best part: You can always turn the microphones back on again if you want to use them. Just make sure you’re careful about what you say when they’re on — and don’t forget to turn them off when you’re finished.
