Abstract: Systems, devices, and methods including a computing device with a processor configured to: send a keep-alive signal to a user at a predefined interval; determine an active status of the user if a reply to the keep-alive signal is received prior to an expiration of the predefined interval; determine a non-active status of the user if a reply to the keep-alive signal is not received prior to an expiration of the predefined interval; send a first level transition notification to a first contact list if the determined status of the user is non-active; send a second level transition notification to a second contact list after a first time period has expired and the reply to the keep-alive signal is not received; and send a third level transition notification to a third contact list after a second time period has expired and the reply to the keep-alive signal is not received.
