LocDemo demonstrates the functionality of libwlocate. After startup, it evaluates the current geographic position of the user and displays it within a map. This solution offers geographic localization that works without the use of GPS and without submitting tracking or position data to commercial providers of such services.
libwlocate and the LocDemo application were ported to Android, allowing the default Android geolocation services to be replaced by a variant with better privacy.
