Terms of Service

1. Who we are and what these terms cover

KDPBookKit is an independent website that provides free calculators for authors publishing through Amazon Kindle Direct Publishing (KDP), and — when it opens — a tool that turns a one-sentence description into print-ready book files paid for with credits.

By using the site you agree to these terms. If you do not agree, do not use the site. These terms apply to the website and to any account you create; they do not apply to Amazon KDP itself, which has its own terms.

KDPBookKit is not affiliated with, endorsed by, or sponsored by Amazon. Amazon, Kindle and Kindle Direct Publishing (KDP) are trademarks of Amazon.com, Inc. or its affiliates.

2. Accounts and sign-in

You sign in with a Google account. We do not store a password for you, and we never send you an email asking for one.

You are responsible for keeping access to your Google account secure. If you believe someone else has access to your KDPBookKit account, use "Sign out of all devices" on the settings page and contact us.

You may delete your account at any time from the settings page. Deleting an account removes your credit balance, credit history and saved sessions.

3. The free calculators

The calculators are free to use without an account. Their results are estimates built from Amazon KDP's published rate tables and from stated typesetting assumptions, and every page shows the data date and links the official source.

KDP changes its rates from time to time. We re-check the published rates monthly, but between checks a figure may be out of date. Always confirm critical numbers against your own KDP dashboard before you publish or price a book.

The calculators are provided as-is, without warranty of any kind. They are decision support, not financial or legal advice.

4. Credits, orders and pricing

Credits are the paid unit of the book builder. Planning, previews and an exact quote are free; credits are spent only when you approve a book.

The book builder is not open yet: credits cannot be purchased at this time, and no orders are being taken. The prices shown on the pricing page are planned prices, published early for transparency.

When the builder opens, prices will be charged in US dollars through Stripe. Credit packs do not expire; subscription credits reset each month and unused subscription credits are not carried over. Subscription credits are spent before pack credits.

We may change prices and credit costs. A change never affects credits you have already bought.

Payments are processed by Stripe. We never receive or store your card details. Your card statement will show the charge from our payment processor.

5. Refunds

Unused credits are refundable within 14 days of purchase, back to the original payment method.

Credits that have already been spent are not refundable, because the generation has already run.

Subscription periods are not refunded once credits from that period have been used; you can stop the renewal at any time and keep access until the end of the period.

To request a refund, email us with the date of purchase and the email address on your account. We reconcile every request against Stripe's records.

6. What you make is yours

You keep the rights to the text, images and files produced for your book, and you keep 100% of your Amazon royalties. We take no share of your sales and no ownership of your work.

You are responsible for what you publish: for the accuracy of the content, for having the rights to any material you supply, and for complying with Amazon KDP's content and AI-disclosure rules. If AI generated the text or images, KDP requires you to disclose it when you publish.

You grant us only the limited licence needed to process your request (for example, generating and storing the files you asked for) and to keep the site running.

7. Acceptable use

You agree not to:

• use the site to break any law, or to infringe anyone's copyright, trademark or privacy;
• generate content that is illegal, hateful, sexually exploitative of minors, or designed to harass a person;
• attempt to bypass credit metering, rate limits or access controls, or probe the service for vulnerabilities without written permission;
• resell or redistribute access to the paid book builder as if it were your own product;
• scrape the site in a way that degrades service for other users.

8. Availability, changes and liability

We aim to keep the site available, but we do not promise uninterrupted service. Features may change, and features labelled as not yet open may be delayed.

To the fullest extent permitted by law, our total liability for any claim relating to the site is limited to the amount you paid us in the 12 months before the claim. We are not liable for lost profits or for Amazon's decisions about your book.

Nothing in these terms limits liability that cannot lawfully be limited.

9. Changes to these terms, and contact

If we change these terms we will update the date at the top of this page. Continuing to use the site after a change means you accept the updated terms.
