Common Questions
Q. Where do I cancel a subscription?
A. App Store subscriptions are managed by your Apple Account. Deleting the JPEDLAB app account or deleting the app does not cancel the subscription. Manage it from iOS Settings or the App Store subscription management screen.
Q. What should I do if a purchase is not reflected?
A. First try Restore Purchases in the app purchase screen. If it still does not work, contact us with the user ID shown in the app, the approximate purchase time, and the App Store state you see.
Q. Can I delete my study history or account?
A. You can delete your JPEDLAB iOS account from the app settings screen. App Store subscriptions still need to be managed separately in your Apple Account.
