If there’s a community spread, we’re able to notify the people who were in the same place, but again, the state knows nothing. If there is no community spread, then everything is deleted after a couple of weeks. So my point is that if you design the data-sharing algorithms right, you can have the public benefit of notifying people when they have been exposed, but you do not have to let anybody else know about the private details—the whereabouts—that they do not know in the first place. So it is a matter of “privacy first” design. It is not a matter of a trade-off.
