Track without sending?

Is it possible to record a track without sending all the points? I'd like to use my Inreach (SE) to track my route pretty closely but have no particular desire (and don't want to spend the cash) to send all those track points to anyone in particular. I just want to be able to download them at the end of the trip so I can see where I've been, with pretty good resolution. A "regular" GPS can do this, of course, but as long as I've got the InReach along for safety and routine communication, I thought I'd try to save some weight...

My first post; hope I've done everything right...
