I don't know LUCA app, but the CoronaWarnApp[1] is not a "tracking application". > The architecture follows a decentralized approach – based on the DP-3T and TCN protocols, as well as the Privacy-Preserving Contact Tracing specifications by Apple and Google. Many, if not most, Corona "tracers" (note, the missing K) at least in Europe, work similar, if only because both Apple's iOS and Googles Android require such an architecture in order for those tracing apps to stay online and stay tracing.
