Is Sprint/TeleNav tracking your destinations?

I was playing around with my new Windows Phone 7 device (HTC Arrive) yesterday and decided to launch TeleNav to check it out.  Well, truthfully, I was lost and needed to find my way home:).  Anyway, I accidentally clicked on “recent places”, and to my surprise, I found addresses I had mapped going back several months – on my previous phone – an Android phone.  I purchased the HTC Arrive less than a week ago and this was the first time I was mapping an address with TeleNav. I remember that I had to enter my mobile number the first time I ran the application, but I thought it was just to register the device.  It appears that was also linking it to a store of my previous destinations – and who knows what else.  I don’t mind caching previous destinations on the device itself, but storing it on some Sprint/TeleNav server bothers me.  Feels like a privacy violation if that information can be used to track where I’ve been.

BTW, I am really liking WP7 and the HTC Arrive.  I am at the evening of my second day without charging the battery.  I have used voice, data (3G and WiFi) and navigation both days, and the battery is still going. My previous phone – Epic 4G (Samsung Galaxy S – Android) could barely run 12 hours with the same sync settings.
