The permissions snippet they show also doesn't include location, and you can't request location at runtime at all without declaring it there.

I'd verify all this stuff for myself, but Play won't install it in my phone so I can't really get the APK. Maybe because I use Graphene...? but I don't know all the ways they can restrict it, maybe it's something else (though for a pixel 9a it's rather strange if it's hardware based).

--- EDIT ---

To be specific / add what I can check, this is what my Play Store "about -> permissions" is showing:

    Version 47.0.1 may request access to
    Other: 
      run at startup
      Google Play license check
      view network connections
      prevent phone from sleeping
      show notifications
      com.google.android.c2dm.permission.RECEIVE
      control vibration
      have full network access

which appears fairly normal, and does not include location, and I think Play includes runtime location requests there. Maybe there's a version-rollout happening, or device-type targeting?
