Am I misunderstanding this? My phone would broadcast a daily unique key that could theoretically be used to track my location?

  No, the daily key is not broadcast; instead it's used to generate a series of rolling identifiers to broadcast. The rolling identifiers change much more frequently. The daily keys don't leave the device until/unless filing a positive diagnosis report.

    As we know from the Bitcoin wallet problems, generating random private key and verifying that it's random is an extremely hard problem. For this reason I wouldn't use any contact tracing app that is not open source.

      You should be happy to know that it's opt in

  Yes, you are. The system would track "I was close enough to persons X, Y, Z phone somewhere at some point in time".
