On startup/relaunch the app does communicate with this server to check to see if an update is available. To assist in determining which iOS device types are using Simple Pedometer to help me plan for future updates (e.g. now that that Simple Pedometer uses Apple's Metal graphics 3D API, can I drop OpenGL support?), the device type is sent during this check, but no other information is retained.
