Terms of Service

Last updated: 2 May 2026

Hi — I'm Daniela, the person behind Kapybara Fun. These are the terms that govern your use of the service. I've tried to keep them readable, but some sections need to be specific for legal reasons. If anything is unclear, email me at support@kapybara.fun.

By creating an account or using Kapybara Fun, you agree to these terms. If you don't agree, please don't use the service.

1. Who I am

Kapybara Fun is operated by Daniela Braierová, based in the Czech Republic. In these terms, “I”, “me”, and “Kapybara Fun” refer to the service and its operator. “You” refers to the person using the service.

2. What the service is

Kapybara Fun (kapybara.fun) is a web service for creating custom puzzle books — mazes, sudoku, word puzzles, and similar — that you can download as PDF files. The service includes a wizard for generating books, a designer tool for customizing layouts, a token-based system for paid features, and optional subscription plans.

The service is offered “as is” and is under active development. Features may be added, changed, or removed over time.

3. Your account

To use most features, you need an account. By creating one, you agree that:

• You're at least 16 years old (or the age of digital consent in your country, if higher)
• The information you provide is accurate and you'll keep it up to date
• You're responsible for keeping your password secure
• You're responsible for everything that happens under your account
• You won't share your account or sell access to it
• Each person needs their own account — accounts are for individual use

If you suspect someone has accessed your account without permission, email me right away.

I may suspend or close accounts that violate these terms, that haven't been used for an extended period, or where I have a legitimate reason to do so (for example, payment fraud or abuse of the service).

4. Acceptable use

Kapybara Fun is for creating puzzle books for personal use, educational use, gifts, or — depending on your plan — commercial publication. You agree not to:

• Use the service for anything illegal
• Generate content that's hateful, harassing, sexually explicit, or that promotes violence
• Generate content that infringes someone else's copyright, trademark, or other rights (for example, puzzle books featuring characters or branded content you don't have rights to use)
• Try to break, overload, reverse-engineer, or interfere with the service
• Try to bypass usage limits, payment systems, or access restrictions
• Scrape or extract content from the service in bulk, or use automated tools to interact with it without permission
• Resell access to the service itself (you can sell the puzzle books you create — that's different)
• Use the service to build a competing product

If you use the service in a way that violates these terms, I may remove the offending content, restrict your account, or close it entirely. For serious or repeated violations, I may do so without refund.

5. Tokens and payments

Tokens. Tokens are a virtual currency used inside Kapybara Fun to generate puzzles and access certain features. Tokens have no cash value outside the service, can't be transferred between accounts, and aren't refundable in cash except as described in the Refund Policy. Tokens never expire as long as your account is active.

Subscriptions. Some plans (like Creator) are recurring subscriptions, billed monthly or annually. Your subscription renews automatically at the end of each billing period unless you cancel. You can cancel anytime from your account settings; cancellation takes effect at the end of the current period.

Lifetime plans. A lifetime plan gives you access for as long as Kapybara Fun continues to operate as a service. “Lifetime” refers to the lifetime of the service, not perpetual access regardless of circumstances. See the Refund Policy for full details.

Payment processing. All payments are processed by Stripe. By making a purchase, you also agree to Stripe's terms. I don't store your card details.

Pricing changes. I may change prices at any time. For active subscriptions, price changes apply at the next renewal, and I'll notify you in advance. Token packs purchased before a price change keep the price you paid.

Refunds. See the Refund Policy for the full details on refunds, the EU 14-day right of withdrawal, and how to request a refund.

6. Your content

“Your content” means anything you create or upload using Kapybara Fun — book titles, custom text, themes, layouts, generated puzzle books, and similar.

You own your content. You keep all rights to the puzzle books you create. I don't claim ownership.

License to me. To run the service, I need a limited license to your content — to store it, process it, generate the PDFs, and let you download and access it. This license is non-exclusive, royalty-free, and lasts only as long as needed to provide the service to you. It ends when you delete your content or close your account (subject to legal retention requirements described in the Privacy Policy).

Your responsibility. You're responsible for making sure your content doesn't violate anyone else's rights. If you upload images, text, or other material, you confirm that you have the right to use it.

Commercial use. Whether you can sell or commercially distribute the puzzle books you create depends on your plan. Free-tier books include a Kapybara Fun watermark and are for personal use only. Paid plans (Creator, Lifetime) include a commercial use license — you can sell, publish, and distribute books you create, including on platforms like Amazon KDP. The commercial license covers books you create with your own content; it does not give you rights to any third-party material that may be incorporated.

7. My content and intellectual property

The Kapybara Fun service itself — including the website, software, designs, brand, logo, and the underlying puzzle generation engine — is owned by me and protected by copyright and other intellectual property laws. You may not copy, modify, redistribute, or create derivative works of the service itself.

The puzzle layouts, fonts, and assets provided by the service for use inside your books are licensed to you for that purpose under your plan.

8. AI-generated content

Some features of Kapybara Fun (currently word-based puzzles like crosswords) use AI to generate puzzle content. A few things to know:

• AI-generated puzzles are produced based on prompts and parameters you provide. The output isn't always perfect — it may occasionally include errors, awkward phrasing, or unexpected results. If a generation fails or is clearly broken, contact me and I'll make it right.
• I don't claim copyright over AI-generated puzzle content created for you. You own the books you create.
• I don't use your content, prompts, or generated outputs to train AI models. AI puzzle generation is provided by third-party AI services (currently Anthropic) that I've selected for their privacy practices.

9. Service availability

I aim to keep Kapybara Fun running smoothly, but I don't promise uninterrupted availability. The service may be temporarily unavailable due to maintenance, technical issues, or factors outside my control. I'll do my best to communicate planned downtime in advance.

I may add, change, or remove features at any time. For paid plans, I won't materially reduce the core features you paid for without notice and a reasonable alternative (refund, credit, or equivalent).

10. If the service is discontinued

Kapybara Fun is a young service, and while I plan to operate it for the long term, I can't guarantee it will exist forever. If I ever have to discontinue the service:

• I'll give all users at least 60 days' notice by email and through the site
• You'll have the chance to download your puzzle books before the service shuts down
• Active subscribers will be refunded for any unused period of their subscription
• Lifetime plan customers will be handled case by case based on how long they had access (see the Refund Policy)
• Token balances at shutdown won't be refunded in cash, but I'll give as much advance warning as possible so you can use them

11. Disclaimers

Kapybara Fun is provided “as is” and “as available”. To the maximum extent permitted by law, I make no warranties — express or implied — about the service, including no warranties of merchantability, fitness for a particular purpose, or non-infringement.

Specifically:

• I don't guarantee that the service will be error-free, uninterrupted, or secure against all threats
• I don't guarantee that generated puzzles will always be unique, solvable in only one way, or free of generation quirks
• I don't guarantee any particular commercial outcome from books you create (for example, sales on KDP)

Where you're a consumer in the EU, this section doesn't limit any rights you have under applicable consumer protection law that can't be excluded by contract.

12. Limitation of liability

To the maximum extent permitted by law, my total liability to you for any claim related to Kapybara Fun — whether in contract, tort, or otherwise — is limited to the greater of:

(a) the amount you paid me in the 12 months before the claim arose, or

(b) €50

I'm not liable for indirect, incidental, consequential, or special damages — including lost profits, lost data, lost opportunities, or business interruption — even if I was aware they could occur.

This limitation applies to the maximum extent permitted by law. If you're a consumer in the EU, certain liability (for death, personal injury, gross negligence, or intentional misconduct) can't be excluded, and this section doesn't limit that.

13. Indemnification

If your use of the service — or content you create with it — causes a third party to bring a claim against me, you agree to defend me, cover my reasonable legal costs, and pay any damages awarded, to the extent the claim arises from your breach of these terms or your violation of someone else's rights.

This doesn't apply to claims caused by my own breach of these terms or my own wrongful conduct.

14. Termination

You can stop using Kapybara Fun at any time. To delete your account, use the account settings or email me.

I may suspend or terminate your access if you violate these terms, if there's payment fraud, if I'm legally required to, or if continuing your access would harm other users or the service. Where reasonable, I'll give you notice and a chance to fix the issue first.

When your account ends:

• Your right to use the service stops immediately
• Your data is handled as described in the Privacy Policy
• Sections of these terms that should reasonably survive termination (payment, intellectual property, disclaimers, liability, governing law) remain in effect

15. Changes to these terms

I may update these terms as the service evolves or as the law changes. The “Last updated” date at the top tells you when. For material changes, I'll notify active users by email or with a notice on the site at least 30 days before the changes take effect. Continuing to use the service after that means you accept the updated terms. If you don't agree, you can close your account.

16. Governing law and disputes

These terms are governed by the laws of the Czech Republic. Disputes that can't be resolved by talking to me first should be brought before the courts of the Czech Republic.

If you're a consumer in the EU, this doesn't deprive you of the protection of mandatory consumer law in your country of residence, and you can also bring proceedings in the courts of your country.

Out-of-court dispute resolution. EU consumers can use the European Commission's Online Dispute Resolution platform at ec.europa.eu/consumers/odr. Czech consumers can also contact the Czech Trade Inspection Authority (Česká obchodní inspekce) for out-of-court dispute resolution.

But honestly — please email me first. Most things can be sorted out in a single message.

17. Other

Entire agreement. These terms, together with the Privacy Policy, Refund Policy, and Cookie Policy, are the complete agreement between us about your use of Kapybara Fun.

Severability. If any part of these terms is found unenforceable, the rest still applies.

No waiver. If I don't enforce a particular term in one situation, I can still enforce it in others.

Assignment. I may transfer my rights and obligations under these terms (for example, if Kapybara Fun is acquired or restructured). You can't transfer yours without my consent.

Contact. For questions about these terms, email support@kapybara.fun.
