I think It would depend on whether the data is meaningfully anonymized.
It would be hard to know for sure if it wasn't without knowing more, but if it really is anonymized before it gets sent back they would just know that user A and user B had been at the same place at the same time last week and user B got the virus and they were together at the same time same place so they just send a notice to user A warning them about the contact with user B. The way I look at it though, is how anonymous can you really be when you sleep at the same place every night with GPS tracking.
