The German "Corona Warn App" (CWA) is pretty good from a privacy POV. It works along the same lines as the Google/Apple ones I think (trading tokens over Bluetooth, then publishing a list of "infected" tokens when you submit a positive test result, risk severity being based on how many tokens you match, i.e. how long you were in the same space). The difference is that it isn't tied to any American corporation.
Of course we also had another app called Luca, which tried to do a lot more direct contact tracing and turned out to be extremely insecure and leak user data, so there's that. And of course there were some plausible corruption allegations relating to its public funding.

Exposure Notifications is not an app, but a framework and a protocol, and CWA was an implementation of it, hooking in the features developed by Apple and Google for iOs and Android [0]: https://github.com/corona-warn-app/cwa-documentation/blob/main/solution_architecture.md#mobile-applications https://github.com/corona-warn-app/cwa-documentation/blob/ma...
- hnbad 3y agoAh, I was under the impression Google and Apple had created their own separate apps and these third-party apps merely worked on the same principle. It's interesting that the document you linked indicates the interoperability between different countries' apps was down to an EU-wide standard. I guess this meant the apps of different EU countries were compatible but only with each other.
