We do not collect any data, neither here on this website nor in our app.
The iOS-app uses your devices sensors, including the camera system, to orient itself in space and in relation to the interviewees. All processing of this data is done in real time on your device, none of is saved, none of it is sent anywhere.
The only value that is saved locally on the iOS device is the playhead position so that the audio can resume from the spot where it was last left off at.
