What does the app do?
The app will passively collect location data. You can also use the app to view your rewards and access the NetDiary. Your data is encrypted and secured in ISTs Cloud Computing Services . We did our best to optimise the battery background performance of the app because continued use of GPS running in the background can dramatically decrease battery life. If you experience any battery issues running the app please contact us directly so that we help you resolve the issue.



What will researchers do with my data?
Your data will be used solely for research aimed at improving campus transportation services as stated in the Informed Consent Form .
