Terms of service

kdpbookai is a web app that helps you make print-ready books for Amazon KDP, with AI tools for text, pictures and files.

Independent product. Not affiliated with Amazon. KDP and Kindle are trademarks of Amazon.com, Inc.

• You sign in with Google. One account is for one person.
• Keep your Google account secure. You are responsible for what happens under your account.
• We may suspend or close an account that breaks these terms or our content policy.
• We run checks to stop people opening many free accounts, as described on the privacy page.

• There is a Free plan, subscriptions (monthly or yearly), a one-time Single book plan and credit packs. Credit packs can be bought only by subscribers. Prices and what each plan includes are on the pricing page.
• Credits pay for AI steps. Credits do not expire while your account is open.
• Payments, taxes and invoices are handled by Lemon Squeezy, who sells to you as the merchant of record. We never see your card number.
• When you change to a bigger plan, you pay the difference for the rest of the period. When you change to a smaller plan, the credits you already have stay.
• You can cancel a subscription at any time. It stops renewing and your plan stays until the end of the period you paid for.
• Refunds are explained on the refund policy.

• You own the books you make: the text, pictures and files made from your prompts. This applies as far as the law allows ownership of work made with AI. We claim no ownership.
• The Free plan is for trying the app, not for selling. To sell your books on KDP or elsewhere, use a paid plan.
• You are responsible for what you publish: that it does not infringe the rights of others, that it follows the rules of the store you sell on, and that you tell KDP when a book was made with AI, as its rules ask.

You give us a limited licence to store and process your content and to send it to the companies that help us run the service (listed on the privacy page). We use it only to run the service for you.

On the Free plan, a book whose print files you download is shared in the community library. You give us the licence we need to show it there. The book is checked automatically and by a moderator before it is listed, and once shared it cannot be made private on the Free plan. Readers can read the book, like it, report it and, if you allow it, start their own book from its recipe (its settings, not its text or pictures). Your print files are never shared. Paid plans keep books private unless you choose to share.

• Text and pictures are made by third-party AI models. They can be wrong or look like existing works.
• Read and check everything before you publish it.
• Our KDP checks lower the chance of a rejection but do not promise that Amazon will accept a book.

Follow the content policy. If a shared book copies your work, use the copyright complaint form and we will look at it.

• We may change, pause or stop parts of the service. We will try to give notice of big changes.
• You can stop using the service at any time. To delete your account, go to Settings, Account, Delete account. Your data is removed as the privacy page describes.
• We may end access for accounts that break these terms.

The service is provided as is, without promises that it will always work or be free of errors.

As far as the law allows, we are not liable for lost profits, lost sales or indirect damage, and our total liability is limited to what you paid us in the 12 months before the claim. Nothing here limits rights that the law gives you and cannot be waived.

We may update these terms. The date at the top shows the latest version. If you keep using the service after a change, you accept it.
