Terms of Use (End-User License Agreement)​

1. Acceptance of Terms

 

Welcome to PekiBook! These Terms of Use (“Terms”) govern your access to and use of the PekiBook mobile application and website (collectively, the “Service”). By downloading, accessing, or using PekiBook, you agree to be bound by these Terms. If you do not agree, you must not use the Service. These Terms form a binding legal agreement between you (the user) and Erenay Kaya (“we,” “us,” or “Developer”), the creator and provider of PekiBook.

 

2. Eligibility and Age Restrictions

 

You must be at least 13 years old (or the minimum legal age in your country to form a binding contract) to use PekiBook. If you are between 13 and 18 (or the age of majority in your jurisdiction), you may only use the Service under the supervision of a parent or legal guardian who agrees to be bound by these Terms. The Service is not directed to children under 13.

 

3. Accounts and Security

 

To use certain features, you may need to create an account. You agree to provide accurate, current information when creating an account and to keep it updated. You are responsible for maintaining the confidentiality of your login credentials and for all activities that occur under your account. If you suspect any unauthorized use of your account, you must notify us immediately. We are not liable for any loss or damage arising from your failure to safeguard your account, including the loss of progress or any virtual items.

 

4. Limited License to Use the Service

 

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use the PekiBook app and access the content for your personal, non-commercial educational use. You may not distribute, sell, resell, or sublicense our app or any content provided through the Service. You also may not copy or reverse engineer the app, nor attempt to extract source code or create derivative works. All rights not expressly granted to you are reserved by the Developer.

 

5. Ownership and Intellectual Property

 

All content, software, and materials made available through PekiBook – including text, lessons, graphics, logos, trademarks, and the design of the app and games – are owned by us or our licensors and are protected by intellectual property laws.

• User Content and Feedback: If you submit any content or feedback (e.g., suggestions, or answers to exercises), you grant us a worldwide, royalty-free, perpetual, sublicensable license to use, reproduce, and adapt that content for the purpose of operating, improving, and promoting the Service. You promise that any content you submit is your own and does not violate any law or anyone’s rights.

• Virtual Items: The Service may include virtual items, such as currency (“gems” or “coins”), character skins, or backgrounds (“Virtual Items”). You acknowledge that these Virtual Items are not real-world currency and have no monetary value. We grant you a limited, revocable license to use these Virtual Items within the Service. You do not own them. We have the absolute right to manage, regulate, control, modify, or eliminate Virtual Items at any time, with or without notice, and we will have no liability to you or any third party if we do so. All sales of Virtual Items are final.

 

6. Acceptable Use Policy

 

You agree to use PekiBook in a lawful and respectful manner. You MUST NOT:

• Use the Service for any illegal purpose.

• Post or transmit any content that is defamatory, fraudulent, obscene, harassing, or infringes on others’ rights.

• Attempt to gain unauthorized access to the Service or another user’s account.

• Use automated means (like bots or scrapers) to access or collect data from the Service without permission.

• Deliberately submit content to the Service’s AI-powered features that is prohibited, hateful, or sexually explicit.

• Use the Service to distribute malicious code, to harass others, or to interfere with or disrupt the Service.

• Attempt to exploit any bugs or glitches in the games or other features for personal gain.

Violation of this policy may result in immediate suspension or termination of your account and forfeiture of all Virtual Items and subscriptions.

 

7. Payments, Subscriptions, Virtual Items, and Refunds

 

PekiBook offers optional paid services. All transactions are processed through the platform you downloaded the app from (the Apple App Store or Google Play Store) and are subject to their respective payment terms.

• Premium Subscription: We offer a paid subscription (“PekiBook Premium”) that provides access to enhanced features, such as an ad-free experience. The fee and billing period will be disclosed at the time of purchase. Subscriptions automatically renew unless you cancel at least 24 hours before the end of the current period through your App Store or Google Play account settings. Please note that an internet connection is still required for many features of the Service, including backups, content updates, and "homework" answer checking.

• Virtual Items and Peki Market: You may purchase Virtual Items (like gems) through the in-app "Peki Market." These are one-time purchases and are separate from the Premium Subscription.

• No Refunds: All purchases, including subscriptions and Virtual Items, are final and non-refundable to the maximum extent permitted by law. We provide no refunds or credits for partial subscription periods, unused features, or lost or unused Virtual Items. If you reside in a jurisdiction with mandatory cancellation or refund rights (e.g., in the EU), we will honor those rights as required by law. Any billing disputes or refund requests must be directed to Apple or Google, who manage the transactions.

 

8. Termination of Use

 

You may stop using PekiBook and delete your account at any time. We reserve the right to suspend or terminate your access to the Service at any time, with or without notice, if we believe you have violated these Terms.

Upon termination, for any reason: (a) your license to use the Service is immediately revoked; (b) you will not be entitled to any refund; (c) your account, progress, achievements, and all associated data may be permanently deleted; and (d) you will forfeit all acquired Virtual Items without compensation.

Sections of these Terms that by their nature should survive termination (such as Ownership, Disclaimers, Limitation of Liability, and Indemnification) will continue to apply.

 

9. AI-Powered Features Disclaimer

 

• AI-Powered Answer Checking: PekiBook may use AI-powered features to evaluate your answers to exercises and "homework" questions. You understand that AI-generated feedback is automated and may occasionally be incorrect, incomplete, or misleading. We do not guarantee the accuracy or reliability of any feedback provided by the AI. You should use this feature as a learning guide only and not for critical assessment.

• User Responsibility: By using these AI features, you agree to use them responsibly. Do not enter personal or sensitive information in your answers.

• No Liability for AI Content: You assume all risk for your use of AI-powered features. We provide them on an “as-is” basis. To the fullest extent allowed by law, we disclaim all liability for any harm or losses arising from your reliance on AI-generated feedback, including any claim that the AI’s evaluation was incorrect.

 

10. Third-Party Services and Links

 

PekiBook may integrate or use third-party services (e.g., cloud hosting, analytics, AI service providers). We may also link to third-party websites or content. These third-party services are not under our control, and we are not responsible for their content, privacy practices, or performance. Your use of these services may be governed by the third party’s own terms and policies.

 

11. Disclaimer of Warranties

 

PEKIBOOK IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT ANY WARRANTIES OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE DEVELOPER DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE. WE DO NOT GUARANTEE THE ACCURACY OF ANY LESSON CONTENT OR AI-GENERATED FEEDBACK.

FURTHERMORE, WE DO NOT GUARANTEE THE PRESERVATION OR BACKUP OF YOUR DATA. ANY DATA YOU PROVIDE OR GENERATE, INCLUDING YOUR LEARNING PROGRESS, GAME SCORES, ACHIEVEMENTS, OR ANY VIRTUAL ITEMS (SUCH AS GEMS, COINS, SKINS, OR BACKGROUNDS), MAY BE LOST, CORRUPTED, OR BECOME UNAVAILABLE AT ANY TIME. OUR BACKUP FEATURES ARE PROVIDED FOR CONVENIENCE ONLY AND MAY FAIL. YOU USE PEKIBOOK AT YOUR OWN RISK.

 

12. Limitation of Liability

 

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL THE DEVELOPER (ERENAY KAYA) BE LIABLE FOR: (A) ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES; OR (B) ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATED TO YOUR USE OF (OR INABILITY TO USE) PEKIBOOK.

THIS INCLUDES, WITHOUT LIMITATION, ANY DAMAGES RESULTING FROM THE LOSS OF YOUR ACCOUNT DATA, LEARNING PROGRESS, GAME DATA, VIRTUAL CURRENCY, OR VIRTUAL ITEMS.

OUR TOTAL CUMULATIVE LIABILITY TO YOU FOR ALL CLAIMS ARISING FROM THE SERVICE WILL NOT EXCEED THE AMOUNT YOU PAID TO US (IF ANY) FOR THE SERVICE IN THE 12 MONTHS IMMEDIATELY PRECEDING THE CLAIM. IF YOU HAVE NOT PAID US ANY AMOUNT, OUR LIABILITY TO YOU IS ZERO.

THESE LIMITATIONS DO NOT EXCLUDE LIABILITY THAT CANNOT BE EXCLUDED BY LAW, SUCH AS FOR GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT.

 

13. Indemnification

 

You agree to indemnify, defend, and hold harmless the Developer (Erenay Kaya) from any and all claims, liabilities, damages, and expenses (including reasonable attorneys’ fees) that arise from: (1) your use of the Service; (2) any content you submit to the Service; (3) your violation of these Terms or any applicable law; or (4) your infringement of any third-party rights. We reserve the right to assume the exclusive defense of any matter subject to indemnification by you, and you agree to cooperate with our defense.

 

14. Governing Law and Dispute Resolution

 

These Terms shall be governed by the laws of the Republic of Turkey, without regard to its conflict of laws principles. You and we agree that any legal proceedings will be brought in the courts of Ankara, Turkey. If you are a consumer residing outside of Turkey, mandatory provisions of your local law may also apply. We encourage you to contact us first to resolve any issue informally.

 

15. Changes to These Terms

 

We may update these Terms from time to time. If we make material changes, we will notify you through the app or by other means. Your continued use of PekiBook after the changes become effective constitutes your acceptance of the new Terms. If you do not agree, you must stop using the Service.
