I'm trying to decide whether or not to use the Your Phone app on Windows, and not finding much information on it.
It requires a Microsoft account, but I don't really see why that should be necessary for a local connection between my phone and my computer. It makes me wonder about the privacy implications.
This page claims the following, but I find it unsatisfactory:
Your Phone relies on local connections through Wi-Fi (the iPhone also needs Bluetooth), but the system never takes your data and stores it on Microsoft's servers. When disconnected there is no maintained data, but rather a local cache on the user's PC for some items.
In particular, "relying" on local connections and not "storing" it on Microsoft's servers is not the same thing as "never sending data over the internet" to begin with. What I want to know is if they transmit any of my phone (or PC's...) data over the internet in the first place, or whether all data stays local to my network. If they send some of my data over the internet but promise not to look at it, that is not the same thing to me as not sending it in the first place.
So: does the app send any kind of data from my phone over the internet (except my login credentials, obviously)?
Is there a way to ensure it keeps all my data within the LAN (whether it's app data, SMS, call, whatever)?
