Simplified explanation of data security ( Free toggl )

So, planning a quick evaluation of the Toggl Time Tracker - specifically the background “Automatic” activity logger feature.

Can someone direct me to a concise explanation of precisely what data is collected, and the format of the logs, (etc)? It’s for a law enforcement agency so I need to have a clear understanding of exactly what data is being collected and potentially exposed in the supporting infrastructure. Is it CONFIGURABLE??

If its just something like

App name - Start Time - Stop Time - total time that would be ideal.

BUT, If the data collected is more like

Chrome Browser - URL abc@xyz.com - Start Time - Stop Time - total time

MS Word - Filename.ext - Start Time - Stop Time - total time

then that would not be suitable for our potential applications…

TIA
