Android contact tracing apps leak location data

When Google and Apple announced their joint platform for contact tracing, the companies said the system would not track users’ locations. By mid-July, the resulting apps had been downloaded more than 20 million times in companies such as Germany and Switzerland. However, in order for Bluetooth, which the app requires, to work on Android phones, users must enable location services, with the result that Google may be able to track their location. Governments and health officials in Germany, Switzerland, Latvia, and Denmark have all raised concerns about how Google uses location data.
