Effective date: November 3, 2026
Last updated: November 6, 2026

Welcome to Puzzlil. These Terms of Service ("Terms") are an agreement between you and Puzzlil ("Puzzlil", "we", "us") and govern your use of our website at puzzlil.online and the Puzzlil web app (together, the "Service").

By creating an account, starting a free trial, buying a subscription or otherwise using the Service, you agree to these Terms and to our Privacy Policy. If you don't agree, please don't use the Service.

Questions? Email puzzlilweb@gmail.com.

1. What Puzzlil does

Puzzlil is a web app that helps you create print-ready puzzle book interiors, including sudoku, word search, maze and Samurai sudoku puzzles with answer keys, and export them as PDF files for print-on-demand platforms such as Amazon Kindle Direct Publishing ("KDP").

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

2. Who can use Puzzlil

Puzzlil is a general-audience tool. If you are under 18, you must have a parent's or guardian's permission to use the Service and to buy a subscription, and they agree to these Terms on your behalf. You must give accurate information when you create an account.

3. Your account

  • You can sign up with an email and password, or with Google.
  • Keep your login details safe. You are responsible for everything that happens under your account.
  • Tell us right away at puzzlilweb@gmail.com if you think someone has accessed your account without permission.

4. Free trial, subscriptions and payment

Merchant of record. Subscriptions are sold and processed by our payment partner Freemius, which acts as the merchant of record and reseller. Freemius handles checkout, payments, invoices, sales tax and VAT. When you buy, you also agree to Freemius's terms shown at checkout.

Free trial. New users can get a 3-day free trial of Puzzlil Pro. A valid card or PayPal account is required to start the trial. You will not be charged during the trial. If you don't cancel before the trial ends, your subscription starts automatically and you are charged the price shown at checkout. Freemius sends you a reminder email before the trial ends. One trial per person.

Plans and prices. Puzzlil Pro is $4.99 per month or $39.99 per year (USD). New monthly subscribers may be offered an introductory price for their first month (for example $1.99); after that first month, the regular monthly price applies. The exact amounts and dates are shown at checkout before you confirm, and the prices shown at checkout are final. Taxes may be added depending on where you live.

Automatic renewal. Your subscription renews automatically at the end of each billing period (monthly or yearly) at the then-current price, and the payment method you provided is charged, until you cancel.

Cancelling. You can cancel at any time from the Billing page ("Manage subscription"). After you cancel, you keep access until the end of the period you have already paid for, and you will not be charged again. Cancelling does not give a refund for the current period, except as described in section 5.

Price changes. We may change our prices. If we do, we will tell you in advance, and the new price will only apply from your next billing period after the notice. If you don't agree, you can cancel before the new price applies.

Failed payments. If a renewal payment fails, Freemius may retry it. If payment cannot be collected, your access to paid features may be paused or ended.

5. Refunds

We offer a 7-day money-back guarantee for technical problems. If, within 7 days of a payment, you experience a technical issue that makes Puzzlil unusable and we cannot fix it, we will refund that payment in full. Email puzzlilweb@gmail.com with a description of the problem, and give us a chance to fix it first.

Refunds are not given for:

  • missing features;
  • problems caused by third-party services or software;
  • finding a different tool you prefer;
  • changing your mind.

Approved refunds are processed by Freemius to your original payment method. Nothing in these Terms limits any refund rights you have under the laws of your country.

6. Your content and the books you make

Your inputs. You keep ownership of the content you put into Puzzlil, such as your word lists, book titles and other text ("Your Inputs"). You give us permission to store and process Your Inputs only as needed to run the Service for you.

Your books. The puzzle book interiors and PDFs you create and export with Puzzlil ("Your Books") belong to you. You may use, publish and sell Your Books commercially, including on Amazon KDP and other platforms, and this permission continues after your trial or subscription ends.

Puzzles are not exclusive. Puzzles are generated by algorithms, and other users may create similar or identical puzzles. We do not guarantee that any puzzle is unique to you, and we don't give you exclusive rights to any particular puzzle, layout or design element that the Service provides.

When we can withdraw permission. We may withdraw your permission to sell a book made with Puzzlil, and ask you to remove it from sale, if that book breaks these Terms. This includes books that contain illegal, hateful, abusive or infringing content, or that use the Puzzlil name or logo in a misleading or damaging way. If we ask, you agree to remove the book from sale promptly. We cannot and do not remove books from Amazon or any other platform ourselves.

You are responsible for your books. Before publishing, check your files, titles, covers and content yourself. You are responsible for making sure Your Books and Your Inputs do not infringe anyone else's rights (including trademarks and copyrights) and that they meet the rules of the platforms you publish on. We do not guarantee that KDP or any other platform will accept your book, or that it will sell.

Showcasing. We may occasionally show anonymous sample pages or puzzles made with Puzzlil in our marketing. These will not include your name or personal details. If you'd prefer that we don't, email us and we will exclude your content.

7. Feedback

If you send us feedback, ideas or suggestions, we may use them freely to improve Puzzlil, without any obligation or payment to you. We may also quote customer feedback as a testimonial using your first name only. Email us anytime to have a quote removed.

8. Acceptable use

You agree not to:

  • scrape, crawl or extract data from the Service, or access it with bots, scripts or other automated means (other than normal use of your browser);
  • copy, clone, reverse engineer, decompile or try to recreate the Service, its puzzle generators or its source code, or build a competing product using it;
  • interfere with or disrupt the Service, try to get around security, access limits or payment, or access accounts or data that aren't yours;
  • use the Service to create or share content that is illegal, hateful, harassing, sexually explicit involving minors, threatening, defamatory, or that infringes anyone's intellectual property or trademarks;
  • use the Service in any way that breaks the law.

9. Our intellectual property

The Service, including its software, puzzle generators, design, text, the Puzzlil name, logo and branding, belongs to Puzzlil and is protected by intellectual property laws. Subject to these Terms, we give you a limited, personal, non-transferable right to use the Service while your account is active. You may not use the Puzzlil name or logo without our written permission, except to truthfully say that a book was made with Puzzlil.

10. Suspension and termination

  • By you: you can stop using Puzzlil and delete your account at any time from your account settings. Please cancel any active subscription first.
  • By us: we may suspend or close your account if you break these Terms, misuse the Service, or if we are required to by law. Where reasonable, we will tell you first and give you a chance to fix the problem. If we close your account for reasons other than a breach of these Terms, we will refund any unused prepaid period.
  • If we stop offering the Service entirely, we will give you reasonable notice and refund any unused prepaid period.

Sections 6 (except the permission to use the Service), 7, 9, 11, 12, 13 and 14 continue after your account ends.

11. Disclaimers

The Service is provided "as is" and "as available". To the fullest extent permitted by law, we make no warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement. We work hard to make sure puzzles are correct and files meet KDP's formatting requirements, but we don't guarantee that the Service will be error-free, uninterrupted, or that every puzzle or file will be perfect. Always review your files before publishing.

12. Limitation of liability

To the fullest extent permitted by law:

  • Puzzlil will not be liable for any indirect, incidental, special, consequential or punitive damages, or for lost profits, lost sales, lost data or business interruption, arising from or related to your use of the Service.
  • Our total liability for any claim related to the Service is limited to the amount you paid us in the 12 months before the claim, or US $50, whichever is greater.

Some places don't allow these limits, so they may not fully apply to you.

13. Indemnity

You agree to defend and hold Puzzlil harmless from any claims, losses or costs (including reasonable legal fees) arising from Your Inputs, Your Books, or your breach of these Terms or the law.

14. Governing law and disputes

These Terms are governed by the laws of the United States, without regard to conflict-of-law rules. Before starting any formal dispute, please email us at puzzlilweb@gmail.com so we can try to resolve it informally. If we can't resolve it within 30 days, either of us may bring the dispute in a court of competent jurisdiction in the United States. Nothing here stops either of us from seeking urgent relief, or removes any mandatory consumer protection rights you have in your country.

15. Changes to these Terms

We may update these Terms from time to time. We will change the "Last updated" date, and if the changes are significant, we will notify you by email or in the app before they take effect. If you keep using the Service after the changes take effect, you accept the new Terms.

16. General

  • Transfer: we may transfer these Terms to a new owner if Puzzlil is sold, merged or transferred. You may not transfer your account or these Terms without our permission.
  • Whole agreement: these Terms and our Privacy Policy are the entire agreement between you and us about the Service.
  • Severability: if any part of these Terms is found unenforceable, the rest stays in effect.
  • No waiver: if we don't enforce a part of these Terms, that doesn't mean we give up the right to enforce it later.
