That's odd, since the NZ Covid Tracer app definitely has this feature, it's part of the standard process when someone tests positive.
As far as I know it only includes the manually scanned codes though, not the bluetooth proximity tracing data. Perhaps the NHS app was trying to gather this?
Perhaps there's some details missing from the article, because it sounds just like how the NZ app operates. All data stays on your phone unless you choose to share it:
"The information you choose to record with NZ COVID Tracer is stored on your phone where only you can see it. This includes the QR codes you scan, your manual diary entries, your Bluetooth ‘keys’, and your NHI number."
If you're identified as a potential case, then you can choose whether or not you want to share your history:
"If you are identified as a confirmed or probable case of COVID-19, it is entirely your choice whether to share your digital diary with the Ministry or upload your Bluetooth keys. You are in control of your data."
> the terms and conditions in more detail says that "a contact tracing app may not use location-based APIs... and may not collect any device information to identify the precise location of users".
I also wondered about this. The NZ app doesn't as far as I know log or transmit GPS coordinates. Some organisations have different codes at every door and in each elevator.
It works the same in HK, once you test positive, you input your case number, and upload your check in history to some government servers. I assumed this is how every country does it.
