How do I unlock the full course?

Open any locked module, or go to Me and tap Unlock the full course. It’s a one-time purchase through the App Store or Google Play. There’s no subscription.

I bought the unlock but it’s still locked.

Go to Me and tap Restore a purchase, signed in to the same Apple or Google account you bought it with. If a parent approved it through Ask to Buy, it opens once the approval goes through.

Can I use it on more than one device?

Yes, on devices signed in to the same Apple or Google account. Use Restore a purchase on the second one. Progress stays on each device, because nothing is stored online.

How do I start over?

Me, then Start over. It wipes your progress, cards and story on that device. There’s no undo.

Do I need internet?

No. The app works entirely offline. You only need a connection to buy or restore the unlock.

I found a mistake in a lesson.
