How to Stop Your Phone from Tracking You through Ultrasonic Audio

Your phone may be listening in on your conversations without your knowledge. This is known as ultrasonic cross-device tracking, which uses inaudible audio beacons to link devices and track your behavior for advertisers. Here’s how to limit or disable it.

To stop this from happening, check your phone’s privacy settings. In the “Privacy” section, you can see which apps have access to your microphone and restrict them if needed. You can also use a secure browser like Brave or Tor, or download a VPN that encrypts your online activity.

While it’s not possible to completely stop ultrasonic beacons, restricting unnecessary permissions granted to apps on your device can reduce the chance of your smartphone listening in. Follow these steps:

1. Open your phone’s settings.
2. Go to the “Privacy” section.
3. Check which apps have access to your microphone.
4. Restrict or revoke permission for any suspicious or unwanted apps.

By taking these steps, you can limit your exposure to ultrasonic cross-device tracking and protect your online privacy.
