A user device includes a wireless interface to establish a wireless personal area network (WPAN) link with another user device. The user device further includes a notification controller to, in response to a link termination event (306) for the WPAN link, selectively trigger a user alert based on at least one of: an indication (312) of whether the user device is in proximity to a user; and an indication (314) of whether the other user device is identified as a user-portable device. The notification controller may selectively trigger a user alert further based on an indication (308) of whether the first device is connected to a specified wireless local area network (WLAN).
