Your smartphone knows where you sleep, work, shop, and travel. That convenience can become a serious privacy risk when location sharing, Bluetooth tracking, or forgotten app permissions fall into the wrong hands. In recent years, security experts and consumer privacy groups have warned about the rise of digital stalking through smartphones and connected devices. The good news is that improving smartphone safety does not require advanced technical skills. Both iPhone and Android devices include built-in settings that can help block unwanted tracking if you know where to look.
