> The app allows people who are required to isolate to opt to do their isolation at home, rather than stay at a quarantine facility. Nobody is being forced to use the app

Weird. In Canada we're allowed to isolate at home without a wildly intrusive app, or police visits or anything like that.

We get a fine if we are caught out when we are required to isolate, that's all.

Personally if my government was proposing this kind of quarantine tracking, I'd be looking to move somewhere sane.
