The Coalition Against Stalkerware defines stalkerware as software, made available directly to individuals, that enables a remote user to monitor the activities on another user's device without consent and without "explicit, persistent notification to that user in a manner that may facilitate intimate partner surveillance, harassment, abuse, stalking, and/or violence."

Mobile applications and PC monitoring software come straight to mind. Unlike spyware, which may be employed to monitor indiscriminately or by government agencies and law enforcement investigations, stalkerware is generally used by individuals.

My fiancee and I have Google Maps Location Sharing turned on for each other. I get periodic emails from Google reminding me that it's turned on. I like that. We both have Android phones, and after reading this article I went to Settings > Privacy > Permission manager and checked to see which apps were given which permissions. I think this is good information, and I hope it's helpful.
