Terms of Service

Last updated: August 12, 2026

These Terms of Service (“Terms”) are a legal agreement between you (“you” or “User”) and NENKAN LLC, a limited liability company organized under the laws of the State of Florida (“NENKAN,” “we,” “us,” or “our”). These Terms govern your access to and use of the SAT Practice website, application, and related services (collectively, the “Service”).

By creating an account, accessing, or using the Service in any way, you agree to be bound by these Terms and by our Privacy Policy, which is incorporated into these Terms by reference. If you do not agree, do not use the Service.

1. Eligibility and Age Requirements

The Service is not directed at, and we do not knowingly collect personal information from, children under the age of 13. You must be at least 13 years old to create an account. If you are between the ages of 13 and 17, you may only use the Service with the involvement and consent of a parent or legal guardian, who must review and agree to these Terms on your behalf and is responsible for your use of the Service. By using the Service, you represent that you meet these requirements.

2. Beta / Experimental Nature of the Service

SAT Practice is an independent research-and-development project, provided as a beta, experimental application. It is not a finished commercial product. Features may be incomplete, may change or be removed without notice, may not function as intended, and may contain errors, inaccuracies, or bugs, including in question content, answer keys, explanations, scoring, or reported statistics. The Service may be modified, suspended, or discontinued at any time, in whole or in part, with or without notice.

3. Fees and Advertising

The Service is currently provided free of charge and without advertising. We may in the future introduce paid features, subscriptions, or other paid tiers, and/or support the Service through advertising. If we do, we will provide notice and, where advertising or paid features involve additional data collection or terms, we will update this Agreement and our Privacy Policy first. Nothing in these Terms obligates you to pay for the Service or to view advertising as it exists today.

4. Accounts

You sign in using your email address and a one-time code (or, where enabled, a password). You are responsible for maintaining the confidentiality of your sign-in method and for all activity that occurs under your account. Notify us promptly if you suspect unauthorized use of your account. You must provide accurate information and may not create an account on behalf of someone else without authorization, share an account, or maintain more than one account per person.

5. Acceptable Use

You agree not to:

  • use the Service for any unlawful purpose or in violation of these Terms;
  • scrape, crawl, reverse-engineer, or use automated means to access the Service or extract its content or underlying data, except through interfaces we officially provide;
  • interfere with or disrupt the integrity or performance of the Service, including by attempting to bypass rate limits, authentication, or other security measures;
  • upload content that infringes the rights of others or that you do not have the right to share;
  • impersonate any person or entity, or misrepresent your affiliation with any person or entity; or
  • use the Service to harass, abuse, or harm another person.

We may suspend or terminate access for anyone who violates this section.

6. Educational and Practice Content

The Service is intended solely for informal, self-directed practice and is not affiliated with, endorsed by, or sponsored by the College Board, which owns the SAT® trademark and is not associated with this Service. Practice questions may be created by us or adapted from third-party study materials for internal, non-commercial educational use. We make no representation that any question, answer, explanation, or format matches or predicts the content, format, or difficulty of any official examination.

If you believe content on the Service infringes your copyright or other rights, contact us at nenkan@protonmail.com with enough detail for us to identify and address the material.

7. No Guarantee of Results

Scores, points, streaks, rankings, and other statistics generated by the Service are for engagement and self-tracking purposes only. We do not guarantee that use of the Service will improve your performance on any examination, result in any particular score, or affect any admissions or other outcome.

8. Intellectual Property

The Service, including its software, design, text, graphics, and all related intellectual property (excluding third-party or user-submitted content), is owned by NENKAN LLC or its licensors and is protected by applicable intellectual property laws. We grant you a limited, revocable, non-exclusive, non-transferable license to access and use the Service for your personal, non-commercial practice. No other rights are granted.

Any feedback, suggestions, or ideas you submit about the Service may be used by us without restriction or obligation to you.

9. Disclaimer of Warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, TIMELY, SECURE, ERROR-FREE, OR ACCURATE, THAT DEFECTS WILL BE CORRECTED, OR THAT THE SERVICE OR THE SERVERS THAT MAKE IT AVAILABLE ARE FREE OF HARMFUL COMPONENTS. NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED FROM THE SERVICE CREATES ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.

10. Assumption of Risk

YOU ACKNOWLEDGE THAT THE SERVICE IS EXPERIMENTAL AND IN BETA, AND YOU VOLUNTARILY ASSUME ALL RISK ARISING FROM YOUR ACCESS TO AND USE OF THE SERVICE, INCLUDING ANY RISK RELATED TO INACCURATE OR INCOMPLETE QUESTION CONTENT, LOSS OF PROGRESS OR DATA, SERVICE INTERRUPTIONS, OR RELIANCE ON THE SERVICE FOR TEST PREPARATION. YOU ARE SOLELY RESPONSIBLE FOR DECIDING WHETHER AND HOW TO USE THE SERVICE, AND FOR ANY DECISIONS YOU MAKE BASED ON IT.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL NENKAN LLC, ITS MEMBERS, MANAGERS, EMPLOYEES, CONTRACTORS, OR AGENTS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, PROFITS, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATED TO YOUR ACCESS TO OR USE OF, OR INABILITY TO ACCESS OR USE, THE SERVICE, REGARDLESS OF THE LEGAL THEORY ASSERTED (INCLUDING CONTRACT, TORT, OR OTHERWISE), AND EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, NENKAN LLC’S TOTAL AGGREGATE LIABILITY TO YOU FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNT YOU PAID TO NENKAN LLC FOR USE OF THE SERVICE IN THE TWELVE (12) MONTHS BEFORE THE CLAIM AROSE, OR (B) FIFTY U.S. DOLLARS (USD $50).

Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above limitations may not apply to you. In that case, our liability will be limited to the fullest extent permitted by applicable law.

12. Indemnification

You agree to defend, indemnify, and hold harmless NENKAN LLC and its members, managers, employees, contractors, and agents from and against any claims, liabilities, damages, losses, and expenses, including reasonable attorneys’ fees, arising out of or in any way connected with your access to or use of the Service, your violation of these Terms, or your violation of any rights of a third party.

13. Termination

We may suspend or terminate your access to the Service at any time, with or without cause or notice, including for suspected violation of these Terms. You may stop using the Service or request deletion of your account at any time by contacting us. Sections of these Terms that by their nature should survive termination (including Sections 8–12 and 15–17) will survive.

14. Changes to the Service or These Terms

We may update these Terms from time to time. If we make material changes, we will update the “Last updated” date above and, where practical, provide additional notice. Continued use of the Service after changes take effect constitutes acceptance of the revised Terms.

15. Governing Law; Dispute Resolution

These Terms are governed by the laws of the State of Florida, without regard to its conflict-of-laws principles. Before filing a claim, you agree to first contact us at nenkan@protonmail.com and attempt in good faith to resolve the dispute informally.

If a dispute is not resolved informally within 30 days, you and NENKAN LLC agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Service will be resolved by binding, individual arbitration, except that either party may bring an individual claim in small claims court, and either party may seek injunctive or other equitable relief in court to prevent actual or threatened infringement, misappropriation, or violation of intellectual property rights. YOU AND NENKAN LLC EACH WAIVE ANY RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS ACTION, CLASS ARBITRATION, OR REPRESENTATIVE PROCEEDING. Any judicial proceeding not subject to arbitration will take place in the state or federal courts located in Florida, and you consent to personal jurisdiction there.

16. Severability; Waiver

If any provision of these Terms is found unenforceable, that provision will be limited or eliminated to the minimum extent necessary, and the remaining provisions will remain in full force and effect. Our failure to enforce any right or provision of these Terms is not a waiver of that right or provision.

17. Entire Agreement

These Terms, together with our Privacy Policy, constitute the entire agreement between you and NENKAN LLC regarding the Service and supersede any prior agreements.
