Wylas Timing does not export any user data to any external site except when reporting a fault in the application. At which point it only reports information necessary to identifying and resolving the bug and supplies that to our account at https://mint.splunk.com/ WT Starter and WT Timekeeper require Record Audio permission so they can intercept the audio jack signal from the electronic starting pistol or touchpad and determine when a race has been started and stopped. The audio is not used for any other purpose and never leaves the device. None of our apps upload *any* data to https://app-measurement.com, but Google’s app checking algorithm seems to be generating a false positive saying that we do. We believe the Google Firebase Analytics libraries are capable of uploading to app-measurement.com in the background. See https://stackoverflow.com/questions/54461349/how-to-decrypt-firebase-requests-to-app-measurement-com/54463682 We're not using any of the Google Firebase Analytics libraries, but apparently one of the other Google libraries is. If you have concerns about this then you should contact Google. We've tried to, they won’t respond.
