What is Stalkerware and How Does It Spy on Your Phone?

Direct Answer

Stalkerware is a type of software that allows someone to secretly monitor your phone activity, including messages, calls, and location, without your knowledge. It is often installed by someone with physical access to your device and runs silently in the background. While sometimes marketed as monitoring tools, stalkerware is commonly misused for surveillance and control.
