I DO NOT STORE ANY OF YOUR DATA. EVER. I physically can't. I have nowhere to store it.
I don’t even have a server any of the apps could connect to, or even a database to store it. So if the FBI asked to see your data, I wouldn’t have anything to show them.
For the SmoothTrack app, this of course also includes any information collected by the camera or TrueDepth API...this data is ONLY sent to your own PC.
