As others have pointed out, you explicitly have to turn it on and install a local exposure notification app for the feature to even be enabled. But I would also suggest you learn how this feature works in the first place, it's an interesting design that makes clever use of Bluetooth and cryptography. It's likely much more private than the way you have your device set up right now. The complete specs, including what is being broadcast over Bluetooth and the cryptography used to preserve privacy, are available here (the Google and Apple system are one and the same): https://www.google.com/covid19/exposurenotifications/#exposure-notifications-and-privacy https://www.google.com/covid19/exposurenotifications/#exposu... These are pretty technical, but this is a good high-level overview: https://www.google.com/covid19/exposurenotifications/#grid-homepage-how-it-works https://www.google.com/covid19/exposurenotifications/#grid-h...
