Terms of Use

Last updated: July 2026

These terms govern use of the xibalbasoftware.com website and of the mobile apps, games, and web services published under the name Xibalba Software. If you download, install, open, or use them, you accept the terms. If you do not accept them, do not use them.

The original of this text is Turkish. Translations into other languages are for information only; in case of conflict, the Turkish text prevails.

1. Who you are contracting with

Haldun Akkoyunlu (Xibalba Software)

Email: info@xibalbasoftware.com

Web: https://www.xibalbasoftware.com

Xibalba Software is not a company; it is the trade name used by a natural person resident in Turkey.

2. Scope

These terms cover: the website; the apps and games TerfiNET, Flash Weaver, Baby Grow Sense, Word Warp, Husky Rush, Block Grid X, Medieval Tides: Orya Wars, Pixel Kicker, Pixel Racket, Pixel Jump Basket, Pixel Hand Egg, Light Trail, and Heka; and the web services CadeNET and PurgioNet. In the rest of this text we call all of them "Products" together.

If a product has additional terms published within it, those additional terms take precedence for that product; on everything else, this text applies.

3. Age

To use the Products and accept these terms, you must meet the minimum age in your country. Most of our games and apps are aimed at a general audience; they are not directed at children under 13. If the digital age of consent is higher in your country — it can go up to 16 in the European Union — parental or legal guardian approval is required for use.

Baby Grow Sense is for adults. By opening an account you represent that you are an adult and that you are authorised with respect to the baby information you enter.

4. Licence granted to you

Subject to your compliance with these terms and the relevant store rules, we grant you a limited, non-exclusive, non-transferable, and revocable licence to use the Products for personal, non-commercial purposes. This is not a sale; you do not own the software.

5. Accounts

Some Products require an account. You are responsible for the accuracy of the information you provide, for protecting your password, and for activity on your account. When asked, you must verify your email address. We may suspend or close accounts that violate the terms, put others' safety at risk, or appear to be fake; where possible, we notify you in advance.

6. What you must not do

  • Copy, reproduce, sell, rent, or create derivative works from the Products without our written permission
  • Reverse-engineer except where mandatory law expressly allows it
  • Use cheat software, exploit vulnerabilities, or manipulate leaderboards or the economy
  • Overload the service with automated tools or scrape content in bulk
  • Use the Products for unlawful, harmful, or fraudulent purposes
  • Attempt unauthorised access or try to bypass security measures
  • Upload content that is unlawful or that infringes someone else's rights

    • 7. Paid content and subscriptions

    In-app purchases and subscriptions in mobile apps and games are billed through Google Play, Apple App Store, or Samsung Galaxy Store. The PurgioNet subscription is billed through LemonSqueezy, acting as merchant of record, and tax obligations sit with it. We never receive your card details.

  • Prices may vary by country and currency; the amount you will pay is shown to you before purchase.
  • Subscriptions renew automatically at the end of the period unless you cancel. The renewal price and date are stated on the purchase screen.
  • Cancellation is done from the relevant store's subscription settings or from your LemonSqueezy account. After you cancel, access continues until the end of the period you paid for.
  • If there is a **price change**, reasonable advance notice is given before it takes effect, and where the law requires it, your approval is obtained.

    • 8. Right of withdrawal and refunds

    For purchases made through a store, you must send the refund request to the store where you paid; they handle the process. For a PurgioNet subscription, you may send your request to us or to LemonSqueezy.

    Consumers in the European Union, the European Economic Area, the United Kingdom, and countries with similar protections have a fourteen-day right of withdrawal for digital content and services. If at the time of purchase you agree to immediate delivery of the content and accept that the right of withdrawal will end, that right lapses. In Turkey, the exception in the Distance Contracts Regulation for services performed immediately in an electronic environment applies.

    These exceptions do not remove your statutory rights if the product is defective. If what you bought does not work as promised, your rights to repair, replacement, price reduction, and refund under the consumer law of your country remain.

    9. Virtual items and in-game currency

    Some games include gold, tokens, cosmetics, and similar virtual items. These are a limited right of use granted to you; they are not ownership, have no cash value outside the game, and cannot be exchanged for real money or with each other. If a game is discontinued, no separate refund is given for virtual items except where the law requires it; in that case we try to give reasonable advance notice.

    Nothing sold for money in our games gives a player a competitive advantage. Expansion packs unlock content that has already been produced.

    10. Ads

    Ads may be shown in free versions. We are not responsible for the content of ads or for advertisers' sites. You can manage ad preferences from device settings and, on the web, from the consent screen. Baby Grow Sense does not use full-screen or rewarded video ads.

    11. AI-generated content

    Text, questions, visuals, and music in some Products are produced with AI tools. This content is reviewed before publication, but it can still contain errors.

    For TerfiNET specifically: questions and explanations are generated originally; real exam questions are not copied. The app is a study tool; it does not replace official legislation, institutional announcements, or exam guides, and no exam result is guaranteed.

    For Baby Grow Sense specifically: developmental information in the app is for general information only and does not replace medical diagnosis or treatment. Always consult your doctor for decisions about your baby's health.

    12. Services that run on your device

    PurgioNet and similar tools process your files on your device. That is good for your privacy, but it also leaves part of the responsibility with you: you should back up important files against the chance of corruption during processing. We are not responsible for data loss caused by your not making a backup.

    You are also responsible for how you use these tools' output. For example, stripping metadata from a document does not mean that sharing that document is lawful.

    13. Availability of web services

    Web services such as CadeNET and PurgioNet are offered without a promise of uninterrupted operation. Temporary outages may occur because of maintenance, updates, infrastructure failure, or abuse. We may apply reasonable quotas and rate limits for fair use.

    14. Your content and feedback

    If you upload content to a Product (for example a username or a shared score), you remain the owner of that content; you only grant us permission to use it to the extent needed to run the service. We may remove content that is unlawful or that infringes someone else's rights.

    If you voluntarily send us a suggestion or idea, we may use it without taking on an obligation. That means what you send will not be kept confidential; do not send confidential information.

    15. Intellectual property

    Everything in the Products — including code, visuals, sounds, texts, characters, world names, logos, and trademarks — belongs to Haldun Akkoyunlu (Xibalba Software) or its licensors. These terms do not transfer any ownership to you.

    Products may use third-party open-source components and models. Those are subject to their own licences, and these terms do not limit the rights those licences grant you.

    If you believe your work has been used without permission, write to info@xibalbasoftware.com; we will review notices that include information establishing the right and, if needed, remove the content.

    16. Early access, changes, and discontinuation

    The Products continue to be developed. We may add, change, or remove features. If a Product must be discontinued entirely, we give as much advance notice as possible and, where reasonable, time for you to export your data.

    17. Disclaimer of warranties

    To the maximum extent permitted by law, the Products are provided "as is" and "as available". There is no promise that they will run uninterrupted, error-free, or fit for a particular purpose. Warranties required by the consumer law of your country remain and are not removed by this clause.

    18. Limitation of liability

    To the maximum extent permitted by applicable law, we are not liable for indirect, incidental, special, or consequential damages, data loss, lost profits, or loss of reputation.

    Our total liability relating to a Product cannot exceed the amount you paid us for that Product in the twelve months before the claim arose; if you paid nothing, it cannot exceed fifty US dollars or the equivalent.

    These limits do not apply to damages arising from our intent or gross negligence, death or personal injury, fraud, and other cases that cannot be limited by law.

    19. Termination

    You may stop using the Products anytime and have your account deleted. We may suspend or end your access in case of a breach of the terms, legal risk, or discontinuation of the product. Clauses that by their nature should survive — such as intellectual property, limitation of liability, and dispute provisions — remain in effect after termination.

    20. Changes to the terms

    We may update these terms. The current version always lives on this page. If there is a material change, we announce it a reasonable time before it takes effect; continuing to use after the announcement means acceptance. If the law also requires express consent, we obtain that separately.

    21. Governing law and disputes

    These terms are governed by the law of the Republic of Turkey, excluding conflict-of-laws rules, and the courts and enforcement offices of Turkey have jurisdiction.

    This clause does not remove the non-waivable consumer protection rules of the country where you are located as a consumer. Consumers in the European Union, the United Kingdom, and countries with similar regulation may continue to exercise rights under their country's mandatory consumer law and to bring claims in their country's courts. Consumers in Turkey may apply to Consumer Arbitration Committees or Consumer Courts within the monetary limits. Consumers in the European Union may also use the European Commission's online dispute resolution platform.

    If a problem arises, we ask that you write to info@xibalbasoftware.com before taking formal routes. Most things are resolved in a few emails.

    22. Other provisions

  • If one clause is found invalid, the others are not affected; the invalid clause is applied in the valid form closest to its purpose.
  • Our not exercising a right immediately does not mean we waive that right.
  • We may assign our rights and obligations under these terms in a transfer or merger, provided your level of protection is not reduced.
  • We are not responsible for delays arising from events reasonably beyond our control, such as natural disasters, infrastructure failure, cyberattacks, and official decisions.
  • The Products may not be used in countries subject to export control or sanctions, or by persons subject to them.
