These apps are helpful for tracing but aren't this app also is causing a possible repercussion on the users' end?
You are on point however the app asks about let's say your personal info so until then the user will decide if and when to share their data.
It is a requirement as it's a tracing app. I've seen also some posts on the web that it's already integrated to our phones, I haven't checked mine if it has the app already.
But if it will quicken the tracing for the active cases and separate them across the people that are not infected, it will help and hoping that the data won't be used and exploited.
