App Support

Support for iPhone, iPad, and Mac apps published by Internet Group Limited.

Restore a purchase

Open the app and select Restore Purchases while signed in to the same Apple Account used for the original purchase. Make sure the device has an internet connection. If access does not update, close and reopen the app, then try Restore Purchases again.

Manage or cancel a subscription

On iPhone or iPad, open Settings → your name → Subscriptions. On Mac, open the App Store → your name → Account Settings → Subscriptions → Manage. Select the app to view or cancel its subscription. Deleting an app does not cancel a subscription, and access continues until the current paid period ends.

Request a refund

Apple processes App Store payments and refund requests. Visit reportaproblem.apple.com, sign in with the purchasing Apple Account, and follow Apple's instructions.

Troubleshooting

Install the latest available version of the app and update iOS, iPadOS, or macOS when possible. Restart the app after an update. Progress and bookmarks in our study apps are generally stored on the device, so they may not transfer after deleting the app or moving to another device.
