In this chapter we’ll talk about description strings, the alerts shown by the system — not you, the developer —, the possibility a user has to revoke an allowance she previously gave you, and where this all happens in the Settings app.
We’ll finish by speaking about the App Store review process, since this is a common subject for the different topics — especially if you’re developing for iOS where there’s barely another alternative.
