Areas for Improvement

  • Data storage protection needs significant strengthening. Sensitive information stored on the device is at elevated risk if the device is accessed by others.
  • Consistent communication security could be applied more broadly throughout the app to reduce the chance of data traveling with less protection than expected.
  • User controls over data collection could be expanded to give users more visibility and choice over what information is gathered and sent to third parties.
