I bought the full course but it’s locked
Open Today, tap the gear at the top right, then Full course → Restore purchases. Use the same Apple Account you bought or subscribed with. The purchase or subscription works on all your iPhones, iPads and Macs.
What happens when the 7-day trial ends?
Nothing is charged and nothing renews. The free lessons stay open, and the rest waits for a monthly subscription or the one-time purchase. Your progress is kept.
How do I cancel the monthly subscription?
In the app: Settings → Full course → Manage subscription. Or in your Apple Account’s subscriptions (on iPhone: Settings → your name → Subscriptions). Cancel at least 24 hours before the next renewal; the course stays open until the paid month ends. If you buy the full course for good, cancel the subscription too, so it stops renewing.
My progress doesn’t appear on my other device
Both devices need the same Apple Account, with iCloud allowed for NavCraft (Settings → your name → iCloud). Settings → iCloud in the app shows the sync state. The first sync can take a few minutes.
I can’t answer questions in the notification
Long-press the notification, or pull it down, to see the A–D buttons. Settings → Reminders & quick questions → Send me a question now sends a test one.
Can I change the lesson language or the colours?
Yes. Settings → Lesson language: Auto, English, Ukrainian or Russian; the essence of each rule is shown and read aloud in that language. Settings → Appearance: Night, Day or Auto.
