My work fleet Volvo V90 hybrid also has it, the remote start is useful, also alerts when left unlocked etc, the Volvo app is much improved with lots of useful functionality / info.My Volvo has it. The subscription lasts 3 years from memory then you pay 49 a year or something. It does get used - messages us if you’ve left it unlocked (we do that a lot for some reason) and the remote start in winter is useful.
It's a 2021 as I'm still ignoring all the messages to change the car to a full EV, I don't know how the subscription works but it is still working with no alerts to resubscribe etc.
As for where the data is stored / gets used etc. I could care less..
