BD Crash Alerter checks to make sure the Black Desert process is running on your computer. If it's running, it will then check the Windows connection table to see if you are connected to the game servers. If at any point your game crashes or disconnects from the servers, a notification will be sent to you (text message, email, or both)!
There is no reason you would get banned for using this program. It does not inject into the Black Desert process, and exclusively uses Windows system calls to determine if Black Desert is running and connected.
