Terms of Service
Last updated November 10, 2026
These terms govern your use of kdpbook.us. By creating an account or using the service you agree to them.
The service
kdpbook.us lets you plan, write and illustrate books with AI and export interior, cover and ebook files for publishing, including on Amazon KDP. Features, limits and prices may change over time.
Your account
You must provide accurate information, keep your sign-in secure, and be at least 18. You are responsible for activity on your account.
Plans, credits and payments
- Generation uses credits. New accounts receive free credits once; paid plans add monthly or yearly credits and remove the preview watermark.
- Subscriptions renew until cancelled. Cancel any time; access to paid features continues until the end of the paid period.
- Payments are processed by Whop. Prices exclude any applicable tax, which is calculated at checkout.
- Credit packs are one-time purchases and do not expire. Unused monthly plan credits do not roll over unless your plan says so.
- Credits reserved for a book that fails to generate are returned to your balance.
Your content and AI output
You keep the rights you have in the prompts and text you provide. Subject to these terms and your plan, you may use the books and images generated for you, including commercially on paid plans. AI output may be similar to output produced for others and may contain mistakes; you are responsible for reviewing it before you publish.
Amazon KDP and other retailers have their own content, disclosure and quality rules, including rules about AI-generated content. You are responsible for following them. kdpbook.us does not guarantee that any book will be accepted or will sell.
Books made on the Free plan may be shown in the community library.
Acceptable use
- Do not use the service to create illegal, hateful, sexually explicit content involving minors, or content that infringes others' rights.
- Do not attempt to bypass credit limits, generation limits or security, or use automated means to access the service other than through our interface.
- Do not resell access to the service without our permission.
We may remove content or suspend accounts that break these rules.
Refunds
If something goes wrong with a payment or the service, contact us through the Feedback option in the app within 14 days and we will review it fairly. Credits already used to generate books are generally not refundable.
Availability and liability
The service is provided as is. We work to keep it available but do not guarantee uninterrupted operation. To the extent the law allows, our total liability for any claim is limited to the amount you paid us in the three months before the claim, and we are not liable for indirect or lost-profit damages.
Ending your account
You can delete your account at any time in Settings. We may suspend or end accounts that violate these terms.
Changes
We may update these terms and will change the date above. Continued use after a change means you accept it.
