FAQ

Do you need my card?

No. Free doesn't even need an account; an account is only for saving, versions and sharing.

What happens when I run out of credits?

You keep generating prompts — only the AI buttons pause. Free credits renew daily, Pro credits monthly.

Can I cancel?

Anytime. Pro stays active until the end of the period, then you move to Free; your projects are kept.

Is there a refund?

Yes: a full refund within 14 days of your first purchase, no questions asked. See the Refund Policy.

Invoices and VAT?

Lemon Squeezy collects the payment as merchant of record and emails you a VAT invoice automatically.

I have a discount code — how do I use it?

If you came through a link with the code it's applied automatically; otherwise enter it under 'Add discount' at checkout.
