This page lists Privacy Policies for the HRM Fan&Led mobiles apps
Application does not collect any user data.
Application stores the device’s (HRM Fan or HRM Led) configuration locally on the phone.
Most operations are done locally on your device. There is only one call to an external server, at each start of the application, to see if there is an update for a ROM on your device. The external server is a google drive repository. If there is an update – it is downloaded to your phone and installed on HRM Fan / HRM Led.
