Contact support
Email hello@rocketdigital.ai. Include your device model, operating system, app version and the screen where the problem occurred. A screenshot is helpful when the issue is visual.
If pronunciation is unavailable
Japanese uses the text-to-speech voice installed on your device. Check that a Japanese voice is enabled in the device language or accessibility settings, then reopen the exercise. More detail is available on the Japanese listening practice page.
Protecting your learning progress
Course progress is stored locally on your device. Before replacing, resetting or removing the app, check your device backup settings so local data is not lost unexpectedly. See what remains available on the offline Japanese learning app page.
Managing a purchase
Apple or Google securely handles subscriptions and billing. You can manage or cancel a subscription in your app-store account and restore an existing purchase from the Premium screen inside Japanese.
Questions about course content
If a grammar explanation, answer or dictionary entry seems unclear, send the exact Japanese text and the lesson or entry where you found it. Specific reports help us review the correct content quickly. Dictionary details and attribution are explained on the Japanese dictionary page.
