The "Location Demo Project" Android App collects location data (longitude, latitude, start time of a journey) to allow a user to keep a record of the locations that the android phone travels. It collects location data even when the app is not in use. Your location data is sent to https://locationcore.azurewebsites.net/ - which is open for public testing. You can visit this portal (https://locationcore.azurewebsites.net/) to learn about pairing and instructions on using this app.
This app doesn't collect ANY data that identifies you as an individual. Neither your phone number, nor your advertisement id, and nor your IMEI is collected or stored or transmitted by this app.
You can delete your location data after testing this app.
