What is stalkerware?

The Coalition Against Stalkerware defines ‘Stalkerware’ as tools – software programs, apps and devices – that enable someone to secretly spy on another person’s private life via their mobile device. The abuser can remotely monitor the whole device including web searches, geolocation, text messages, photos, voice calls and much more. Such programs are easy to buy and install. They run hidden in the background, without the affected person knowing or giving their consent. Regardless of stalkerware’s availability, the abuser is accountable for using it as a tool and hence for committing this crime.
