I had this set up the day it was available in my area. Never got an alert. I find it difficult to believe I wasn't "exposed" during the pandemic, so I assume this didn't really provide much value.
I ended up getting a few alerts, and each time I tested negative. Then later during Omicron, I ended up getting Covid and was contacted by a contact tracer for the city. I explained to them if they give me the code for the app, I can signal that I have Covid, and they said it wasn't worth it.
Overall I think it was an interesting idea, and the approach was pretty clever while also maintaining privacy. Really the failure was from the municipalities being out of the loop. I'm not sure if there were studies done, but I do wonder how accurate the exposure determination was, since for me it was always false positives.

How are you determining you got a false positive? The app alerts you if you were exposed to someone with COVID while out and about in your day. Just because you didn't catch COVID from your exposure does not mean the app gave you a false positive. Just that you weren't close to them long enough and/or your immune system, hygiene, or luck fought it off.
Only way you could really say you got a "false positive" was if you got an alert, for a certain day but knew that you had 0 interaction with people (you never left the house and no one came over during your alert).
I guess it depended on how many others did it. I've gotten a few of them here in the Netherlands, though in my case they never provided info that I didn't already have. Nevertheless I did see the value of it, in some cases it could be very useful
I'm originally from Brazil but I've been living in Poland for the past decade so I had the Polish app setup with Android covid notifications. The neat thing is that it doesn't matter as they all talk together due to how the protocol works.
I got a few notifications in Poland, and I also did travel to Brazil, and got notifications there too.
The app only works if enough people are in though, so if nobody uses then it won't work. Depends on the area, people, way of thinking.
I had quite a few notifications from it in the UK during the height of the pandemic, though that might be more of an indication of how much our government fucked it up
It's a long shot, but I hope that they keep the exposure notification framework and work with the CDC/appropriate orgs around the world to make it a generic exposure notification. The technical feature is impressive, and the usefulness (with proper adoption) would be high for the various occasions where other communicable diseases pop up. It seems easy enough to have a generic app to add the various diseases and their incubation/transmission windows to allow others to be notified.
But, because people are whiny fucks, it'll die and we'll be in a rush to reimplement it for the next thing that comes up.
Even if it did exist in an ideal state, people would still not use it, because people suck.
Well people would say you have a grim outlook but they can shove it, you're right. But imagine google having an opportunity to cancel a product, they were walking around with raging hard-ons when somebody mentioned they get to cancel something
Good riddance. It's a totalitarian privacy nightmare that never functioned as advertised.
Similar systems were widely deployed in Singapore, on the premise it would only be used to fight COVID. Then to no one's surprise, law enforcement started it using for criminal investigations.
Once they're built, governments cannot resist abusing such systems.
The Google system allegedly shares hashes of a ID-number salted with a rotating timestamp over BLE. But it's also a closed-source binary. Can you or anyone else actually inspect its implementation? Can you really guarantee it doesn't have even the smallest design flaws?
This technology is exceptionally dangerous. There is very little difference between these two scenarios:
A doctor has identified a COVID patient. Let's notify everyone who's spent time with them recently.
Secret police have identified a "dissident". Let's round up all their close associates.
It's voluntary (for now). It's allegedly secure (for now). But did anyone actually benefit from this complicated system? All I see are downsides.
