_{It's true. Your phone really can listen and watch in ways you don't expect. Apps often ask for permission to use your camera, microphone, and location and many people just tap "Allow" without thinking. Once given, that permission can stay on in the background. Some apps use this to collect data about your habits and sell it to advertisers.
 
Others store it without telling you clearly. This is not a rumor it has happened many times, and companies have been caught doing it. So, the next time an ad feels too accurate, it's not magic. It's data.}
