SENS

This app mainly works with the air quality sensors produced by our company.

The app is in offline mode. Therefore no data will be collected by us.

This app uses Bluetooth to communicate with devices. Real-time data will be acquired via Bluetooth Broadcasting, and to get historical data. And a Bluetooth Connection is needed for data synchronization.

All data will be saved in the local database in the App. If users want to get the real value of data, he/she can go to "Data" tab and click the "Email" icon. In such a way, a csv file will be sent through email. In the app, all the stored data will be displayed as a chart.

In the meantime, location data is also be queried if the background location permission is allowed. Some of our devices are portable, so combining with location data, more info can be analyzed.

Reasons why background location is required:
There is a tab that shows users' moving paths, combined with the device data. When the app runs in the background, the app will store the current location information. Then when users synchronize the devices' data with the app, the users' moving routines will be shown. Of course, it is possible for users to not allow the background location. Then the "Location" tab will only display the location information got when the app runs in the foreground.
