Don't let this dim your enthusiasm for the app, but due to a rash of apps on this topic (some of which were spreading false information), it looks like Google (& Apple & Amazon) have suspended publishing of new apps related to COVID-19, unless they are from official/trusted organizations/entities.

So... even though you may not be able to get your app into the Play Store, it could still be an excellent individual project, and you'd learn a lot from making it. (Also, some of your family/friends could still install it directly from downloading the APK file if they wanted to -- and set their app install permissions to allow that.)
