First launch
The very first time you open Play Guess and Reveal, it walks you through the permissions it needs, one at a time, explaining what each one is for. You know why you are saying yes before the system asks the question.
Local network — required
This is the only mandatory permission. The app connects the devices around you without going through the internet: without it, no game is possible, neither hosting nor joining. This screen therefore cannot be skipped.
Apple Music — for hosting
The host draws the excerpts from their Apple Music library. Players don't need it: if you only intend to join games, you can put this one off without losing anything. It will be offered again the day you want to host.
Notifications — to be told
They let you know that a player has joined, or has buzzed in while you were looking away. Optional as well: without them the app works normally, but stays silent while it is in the background.
Under the Later button, each optional screen states exactly what you give up by putting it off.
If you declined
The system only asks once. Once a permission has been declined, the app can no longer ask again itself: the screen switches to Open Settings, which takes you straight to the right place. As soon as you come back, the change is picked up without restarting the app.
The help bubbles
Once the assistant is done, the home screen opens with four short explanations, one per card: host, join, your profile and settings. Step through them with Next, or dismiss them all with Skip. They do not come back afterwards.
Does the assistant come back?
Only for what is still missing. If you remove a permission from your device settings, its screen returns on the next launch. What you deliberately put off, however, is not asked again every time you open the app.
