If you're on Android, you may enjoy the new "Archive" functionality, which uninstalls the app but retains its local data directory so when you tap the icon it re-downloads the apk on top of its existing data directory, so no more first-user experience https://support.google.com/googleplay/answer/15523443?hl=en

I believe it's primary use case is storage efficiency but it works perfectly fine in your use case of preventing the code from running while you're not actively using it
