Thank you for the quick reply.
However, that doesn't make sense logically.
If -- as you say -- no room data is transmitted to HTC, it doesn't matter if I store one room set-up or ten on my PC. Any safety concerns would be entirely my business, how safe or unsafe I keep my computer.
If the data about the environment that is necessary for playing only gets transferred when I actually play in that particular environment, it also makes no difference if I load the relevant map from my PC or create it from scratch every time I play. The exact same data will be transmitted every time.
Is there a way to contact the developers and get things like that added to the "wishlist" for quality of life improvements?
It's a serious pain in the behind to create a new play area three times a day.
It really shouldn't be that difficult to have an option to download room set-ups and save them somewhere on my computer and then load them into the console when I actually want to play in that particular playing area...
