Airlib offers several apps for data collection purposes. They can only be used with an Airlib sensor on-board your car.
The apps will not collect ANY data unless they connect to an Airlib sensor via Bluetooth.
AirlibDCA collects location data in the background even when the app is closed or not in use for the sole purpose of matching the air quality data with locations. This data is used for mapping purposes together with a multitude of similar data from other users. Once used for mapping, the data is not traceable to users and is therefore anonymous.
The map data that is shared with other parties does not therefore carry any information that may link it to a specific app user.
No other data is shared with any other party.
