No, BitsaboutMe is not a contact tracing app. BitsaboutMe receives the anonymous identifiers (EphID) sent out by other contact tracing apps, anonymizes them and makes the encounters transparent to you. But BitsaboutMe does not send any EphID itself and does not receive warnings about possible infections. These functionalities are reserved to official contact tracing apps. We complement such apps by making BLE data transparent and thus also usable for you.
