I'm happy we are getting track and trace up and running.
I work in software development. I don't agree with the model the NHS has opted for. However I will download the app.
They will be collecting a lot of location data and want to use it to study, however it will be anonymous. They talked about taking the first four letters of your postcode only and I believe that was optional.
When they talk about sanctions I'm pretty sure that will not be for those told to self isolate by the app. Quite simply unless you contact a human track and tracer, they wouldn't know who you are. I think it will be for anyone who has tested positive but who is not self isolating, like back at the start of all this when cruise passengers were brought back and got check up calls from PHE.
The app is an additional layer, but won't be adopted by all. People will have privacy concerns, won't have smart phones, have an older model that can't support it or might have a job which prevents them having it with them all the time etc.
The track and trace team are the ones who would ask for your contacts and notify them. Being behind someone in a supermarket queue is unlikely to spread it. The Conservatives won't want to continue to need to pay for people off work self isolating for no reason, it will hamper getting the economy going again. They are using an algorithm to work out risk, so that scenario would be low but chatting to your friend face to face for an hour would be high. That person would need to self isolate and I'm sure would anyway.
The app I think will act as a heads up. Say pubs open again and unknowingly someone who later tests positive has been there. If everyone they spoke to (who the person wouldn't have known details of so couldn't have been reached by the track and trace team) was notified by the app they have the chance to self isolate. By the time that happens, numbers will be so low that testing capacity could be used for testing in this scenario.
There will be no mandatory download of the app and you will not be forced to use it.
But I totally understand people's concerns. A track and trace app sounds concerning at the best of times, so after the way this has all been handled when trust is at an all time low, I'd imagine uptake won't be great.
South Korea had the app ready I believe from SARS, so will be familiar with it and already know what it is / how it will be used and it's benefits. They will have also had a chance to iron out issues. That will have helped in getting it widely used.
If you don't want to use the app, don't worry. You won't need a burner phone or to turn yours off. Just don't download the app when (if) it launches. They won't use credit card data or phone mast pings to track you if you don't have the app, that kind of investigating is used to find missing persons for example and is time consuming and expensive.
