I bought Full Access but it isn’t unlocked

Open Settings (the gear icon on the home screen) and tap Restore purchases. Make sure you’re signed in to the same Apple ID or Google account you used to buy it.

Can I use TideTutor on my iPhone and my iPad?

Yes. Buy once, then use Restore purchases on your other devices signed in to the same Apple ID (or Google account on Android).

How do I get a refund?

Refunds are handled by the store you bought from. For Apple, go to reportaproblem.apple.com. For Google Play, open your order history in the Play Store, or see Google Play’s refund help.

I think an answer is wrong

Please tell us. Every question shows a short question code underneath it (like 222-227A). Email support@tidetutor.com with the code and what you expected, and we’ll check it.

Can I start again from scratch?

Yes: Settings → Reset progress. This clears your progress and revision history on that device. It doesn’t affect your purchase.

Does TideTutor need an internet connection?

No. Everything works offline. The app only talks to the App Store or Google Play when you buy or restore.

What data do you collect?

None. There’s no account, no analytics and no tracking. Your progress stays on your device. See the privacy policy.

Can I use TideTutor for real navigation?

No. TideTutor is a training aid. Every port, chart and tidal figure is invented for practice. At sea, always use official, up-to-date charts and tidal data.
