Terms of service

The rules for using kdpbook.io, written to be read. By creating an account you agree to them.

Last updated

1. Who we are and the service

kdpbook.io (“kdpbook”, “we”, “us”) is operated by THE VIBECODING AGENCY, a French société à responsabilité limitée (SARL) registered in the RCS Paris trade register under number 108 800 616, with its head office at 5 rue de la Moselle, 75019 Paris, France. EU VAT number: FR61108800616. More in our legal notice.

kdpbook is an online studio that uses AI to write, illustrate and lay out books, and exports files formatted for Amazon Kindle Direct Publishing (KDP). kdpbook is independent and not affiliated with, endorsed by or sponsored by Amazon. Kindle Direct Publishing and KDP are trademarks of Amazon.com, Inc.

2. Your account

  • You must be old enough to enter into a contract where you live, and give accurate information when you sign up.
  • One person, one free account. Creating several accounts to collect free credits isn’t allowed and may lead to the accounts being closed.
  • You are responsible for what happens under your account; keep your login secure.

3. Credits

  • Generating books uses credits. New accounts receive 2,000 free credits once. Plans add credits every billing period, and subscribers can buy one-off credit packs. What each step costs is shown on the pricing page.
  • Before a generation starts you see its credit estimate. At launch we hold that estimate (up to 5% more), charge the work actually produced, and release the rest. If a generation fails, what wasn’t produced is not charged.
  • Credits are a prepaid right to use the service: they have no cash value, can’t be transferred or exchanged for money, and are not refundable once used.
  • Credits stay on your balance when a subscription ends. Unused credits are lost when an account is deleted or closed for abuse.

4. Prices and payments

  • Prices are shown on the pricing page and at checkout, in US dollars, excluding tax. VAT or sales tax is added at checkout where it applies, based on your billing address.
  • Payments are processed by Stripe, our payment provider; we never see your full card number. Plans and credit packs are sold by THE VIBECODING AGENCY: every payment comes with a receipt and an invoice, sent by email.
  • Credit packs are paid once, and their credits are added to your balance as soon as the payment is confirmed.

5. Subscriptions

  • Plans are billed monthly or yearly, in advance, and renew automatically at the end of each period until you cancel. Each paid period adds the plan’s credits to your balance (a yearly plan adds the twelve months of credits at once).
  • You can cancel or change plan at any time from the billing portal on your Credits page. When you cancel, you keep your plan until the end of the period already paid, and it is not renewed. The books you made stay in your account.
  • If a renewal payment fails, Stripe retries it for a while; if it still fails, the subscription ends and your account returns to the free plan.
  • If we change the price of a plan, we tell you before it applies to your next renewal, so you can cancel beforehand.

6. Refunds and right of withdrawal

  • Consumers in the European Union and the United Kingdom can withdraw within 14 days of subscribing to a plan (your first payment) or of buying a credit pack, without giving a reason, by writing to contact@thevibecodingagency.fr. Credits are available as soon as you pay, so if you have already used some of them, we refund the payment minus the value of the credits used, in proportion to the price paid. Refunds are made within 14 days, with the payment method you used.
  • Otherwise, payments for periods that have started and for used credits are not refundable, except for a billing error, a failure of the service on our side, or where the law requires it. Write to us: we look at every request.
  • When a payment is refunded, in full or in part, the credits it added are removed from your balance in the same proportion.

7. Your books

  • You keep the rights you have in what you bring to kdpbook: your ideas, prompts, manuscripts and images.
  • On a paid plan, you may use, publish and sell the books you make with kdpbook, including their text and illustrations, without paying us royalties.
  • On the free plan, books are for personal use and evaluation: exports are watermarked and may not be sold. Upgrade and export again to get clean files you can sell.
  • AI-generated content may not be protected by copyright in some countries, and similar prompts can produce similar results for other users. We don’t promise exclusivity over generated content.
  • You are responsible for the books you publish, including declaring AI-generated content to Amazon KDP. See our AI content policy.
  • Free tools (no account): Puzzles you make with the free puzzle makers are yours to use for any purpose, including books you sell on Amazon KDP or elsewhere, and no credit to kdpbook.io is needed. This is about single puzzles made with the free puzzle makers on kdpbook.io/kdp; books made in the studio follow the plan rules above.

8. What you allow us to do

To run the service, you allow us to store, process and display your content, and to send it to our AI and infrastructure providers to generate your book. For books published in the community (all free-plan books, and paid-plan books you make public), you also allow us to show them publicly on kdpbook.io, with their cover, pages and title, including in search results and previews, until you delete them.

9. Acceptable use

Don’t use kdpbook to create content that infringes other people’s rights, imitates real people without permission, sexualizes minors, promotes hate or violence, or breaks the law. Don’t try to break, overload, scrape or resell the service, or get around credit limits. The full list is in our AI content policy. We may remove content and suspend accounts that break these rules.

10. Amazon KDP

We build files to follow KDP’s published specifications and check them before export, but Amazon decides what it publishes. We don’t guarantee that KDP will accept a book, and we are not responsible for KDP’s decisions, rules, prices or royalties, which can change at any time.

11. Availability and changes

We work to keep kdpbook available and your books safe, but the service is provided as it is, and features may change. We may update these terms; if a change matters, we will tell you before it applies. Continuing to use kdpbook after that means you accept the new terms; if you don’t, you can cancel your subscription and delete your account.

12. Liability

To the extent the law allows, kdpbook is not liable for indirect losses such as lost sales or royalties, and our total liability is limited to the amount you paid us in the twelve months before the claim. Nothing in these terms limits rights you have under consumer protection law, or our liability for gross negligence or intentional misconduct.

13. Closing your account

You can stop using kdpbook, delete your books and delete your account from your settings at any time; deleting the account cancels an active subscription. We may close accounts that break these terms. Unused credits are lost when an account is deleted or closed for abuse.

14. Governing law and disputes

  • These terms are governed by French law.
  • If you are a consumer, you keep the protection of the mandatory consumer rules of the country where you live, and you can bring a claim before the courts of that country or before the French courts.
  • If you use kdpbook for your business, the courts of Paris, France, have exclusive jurisdiction.
  • Before going to court, please write to us: most problems are solved by email.
