Karoo 3 User Settings - saved?

General query: are the settings on my new / karoo 3 saved on the app? Just wondering if i need to take photos in case the unit ever crashes? I know workouts ans routes are synched into the app, so fine. Was thinking of profiles, data fields / pages / settings per profile and external sensors?

I'm hoping if i ever need to reset the unit, it will recognise the reset device from before and give me the option to synch everything so it's just like before? I have everything set up just how i like it but I won't remember every setting.

Thanks

Simon
