FAQ

How do I cancel my subscription?

Open the iPhone Settings app → your name at the top → Subscriptions → GrandDesigner Lite. You can keep using it until the end of the period.

My purchase isn't showing after changing devices or reinstalling

Sign in with the same Apple ID, then tap Settings → Restore purchases in the app.

How do I delete my account?

Go to Settings → Delete account in the app. All data, including projects and deliverables, is permanently deleted. Your subscription isn't canceled automatically, so cancel it as described above.

How many AI runs can I use?

The monthly limit is shown in Settings in the app. The count resets on the 1st of each month (Japan time). Failed or canceled runs don't count.

How is my input handled?

It is sent to Anthropic's API for AI processing but is not used to train AI. See the Privacy Policy for details.

Which language are deliverables created in?

You choose Japanese or English for each project in the project settings. The app's screens follow your device language.

How do I use deliverables in PowerPoint, Excel or Word?

Use Open / Share on the deliverable screen to open each format, then send it by email, Files, Teams and more with the Share button.

I'd like a refund
