Common questions
How do I cancel my subscription? iPhone Settings → your name → Subscriptions → Charter Prep → Cancel.
How do I restore a purchase on a new phone? Open the Pro tab and tap "Restore purchases".
Does the app work offline? Yes — the bundled question bank and flashcards work offline; AI generation and the tutor need a connection.
