1. Our Services

The information provided through the Services is not intended for distribution or use by any person or entity in any jurisdiction where such distribution or use would be contrary to applicable law or regulation. Users who access the Services from other locations do so at their own initiative and are solely responsible for compliance with local laws.

The Services are not tailored to comply with industry-specific regulations such as HIPAA, FISMA, or similar frameworks. If your use would be subject to such laws, you may not use the Services.

2. Intellectual Property Rights

We own all intellectual property rights in our Services, including all source code, databases, software, website designs, text, graphics, and trademarks, protected by copyright and trademark laws worldwide. We grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Services for your personal, non-commercial use only.

No part of the Services or its content may be copied, reproduced, distributed, sold, or exploited for any commercial purpose without our express prior written permission. Any unauthorized use constitutes a material breach of these Legal Terms and may result in immediate termination of your access.

You retain ownership of the content you submit. By submitting content, you grant us a limited license to process it solely to deliver the Services to you. By submitting feedback, suggestions, or ideas, you agree we may use them freely for any purpose without compensation or acknowledgment.

3. User Representations

By using the Services, you represent and warrant that:

  • All registration information you provide is true, accurate, current, and complete
  • You will maintain and promptly update such information as necessary
  • You have the legal capacity to enter into a binding agreement
  • You are not a minor in your jurisdiction of residence
  • You will not access the Services through automated or non-human means, including bots or scripts
  • Your use of the Services is for lawful purposes only and will not breach any applicable law

If any information you provide is untrue or incomplete, we reserve the right to suspend or terminate your account and refuse any current or future use of the Services.

4. User Registration and Account

Registration may be required to access certain features. You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us immediately at support@squarexai.com if you suspect unauthorized access. We are not liable for any loss resulting from unauthorized use of your account.

Your account is for your individual use only. Account sharing is strictly prohibited, including sharing login credentials with friends, family, colleagues, or clients. Each user must maintain their own account and subscription. Unauthorized account sharing will result in immediate termination without refund.

We reserve the right to reclaim or change a username that is inappropriate, obscene, or otherwise objectionable at our sole discretion.

5. Purchases and Payments

You must provide current, complete, and accurate purchase and account information for all purchases. You agree to promptly update your account and payment information so that we can complete your transactions. All payments shall be made in the currency specified at the time of purchase. Sales tax may be added as required. Prices are subject to change at any time.

You are responsible for any applicable taxes related to your purchases. We may require documentation for tax compliance purposes. In cases of overdue payments, your access to the Services may be suspended after written notice.

We reserve the right to correct any pricing errors at any time, even after payment has been received, and to refuse, limit, or cancel any order at our sole discretion.

6. Subscriptions and Refunds

By subscribing to our Services, you acknowledge that access to digital features begins immediately upon purchase. You waive any right to a withdrawal or cooling-off period, as resources are allocated and costs are incurred the moment you begin using the Services. All payments are non-refundable.

Your subscription is valid only for the period during which our operations remain active. We do not guarantee the Services will be available for any specified period. If we discontinue operations, subscriptions will terminate immediately without refund.

We reserve the right to adjust pricing, available credits, or service features at any time. Price changes will only take effect at your next renewal.

7. Cancellation

You can cancel your subscription at any time by logging into your account and managing your billing settings. Your cancellation will take effect at the end of the current paid billing period, and you will retain access to the Services until that date.

Cancellation does not entitle you to a refund or credit for any unused portion of your subscription. If you have any questions or are unsatisfied with our Services, please contact us at support@squarexai.com before cancelling.

8. Chargebacks and Payment Disputes

By initiating a chargeback or payment dispute through your bank or payment provider, you acknowledge and agree that we reserve the right to immediately terminate your account, revoke access to all Services, and deny any future use without prior notice. Terminated accounts will not be reinstated under any circumstances, and you are prohibited from creating a new account under any other name, email, or payment method.

Any remaining credits or benefits will be permanently forfeited without refund. If a chargeback is found to be fraudulent or filed in bad faith, we reserve the right to pursue legal action to recover damages, processing fees, and associated costs including attorney fees. Filing a chargeback constitutes a material breach of these Terms.

If you have a billing concern, please contact us at support@squarexai.com before initiating any dispute with your payment provider.

We respect the intellectual property rights of others. If you believe that any material available through our Services infringes a copyright you own or control, please notify us immediately at support@squarexai.com with sufficient detail for us to evaluate the claim.

The Services are hosted and operated from multiple locations. If you access the Services from outside the region in which our servers are located, your information may be transferred to, stored, and processed in a different jurisdiction. By using the Services, you consent to such transfer, storage, and processing in accordance with our Privacy Policy.

16. AI Output Disclaimer

Humanchecker AI is designed to produce text that closely resembles natural, human-like writing. Our models are trained to maximize humanization effectiveness. However, AI detection tools are constantly evolving and may produce inaccurate results, including false positives. We do not guarantee that content processed through our Services will avoid detection by any AI detection tool.

We make no guarantees regarding the accuracy, quality, or suitability of output for any particular use. You are solely responsible for reviewing and editing any output to ensure it meets your requirements. We cannot be held liable if content is flagged by detection software.

17. Ethics and Academic Integrity

Our Services are intended to assist with legitimate writing tasks such as improving clarity, tone, and readability. You are solely responsible for ensuring that your use of the Services complies with the academic integrity policies, honor codes, and institutional rules of any school, university, employer, or organization you are affiliated with.

We do not condone academic dishonesty, plagiarism, or any misuse of AI-generated content in violation of applicable policies. If your institution prohibits the use of AI writing tools, you must comply with those requirements. We expressly disclaim all liability for any consequences arising from your misuse of the Services in violation of such policies.

18. Disclaimer of Warranties

The Services are provided on an “as is” and “as available” basis. You agree that your use of the Services is at your sole risk. To the fullest extent permitted by law, we disclaim all warranties, express or implied, including the implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We make no warranty that the Services will meet your requirements, be available on an uninterrupted, timely, secure, or error-free basis, or that any results obtained from the use of the Services will be accurate or reliable.

We do not warrant that the Services or any content will be accurate, complete, or free of errors, viruses, or other harmful components.

We reserve the right to modify, suspend, or discontinue any part of the Services at any time without notice or liability.

19. Modifications and Interruptions

We may change, modify, or remove the contents of the Services at any time without notice. We do not guarantee that the Services will be available at all times and may experience interruptions, delays, or errors due to hardware, software, maintenance, or circumstances beyond our control, including natural disasters, acts of God, labor disputes, governmental actions, or other force majeure events. Under no circumstances will we be liable for any loss, damage, or inconvenience caused by any unavailability or interruption of the Services.

20. Corrections

There may be errors, inaccuracies, or omissions in the information provided through our Services, including descriptions, pricing, and availability. We reserve the right to correct any errors or update any information at our sole discretion without prior notice.

21. Limitation of Liability

In no event shall SquareX AI Limited, its officers, directors, employees, contractors, agents, licensors, or service providers be liable to you or any third party for any indirect, incidental, special, consequential, exemplary, or punitive damages, including but not limited to lost profits, lost revenue, loss of data, loss of goodwill, service interruption, computer damage, system failure, or the cost of substitute services, arising out of or in connection with your use of or inability to use the Services, even if we have been advised of the possibility of such damages.

Notwithstanding anything to the contrary, our total aggregate liability to you for any cause whatsoever shall not exceed the greater of (a) the amount you paid us in the six (6) months immediately preceding the event giving rise to the claim, or (b) one hundred U.S. dollars ($100). Some jurisdictions do not allow the exclusion or limitation of certain damages, so the above limitations may not apply to you.

22. Indemnification

You agree to defend, indemnify, and hold harmless SquareX AI Limited and its affiliates, officers, directors, agents, partners, and employees from and against any loss, damage, liability, claim, or demand, including reasonable attorney fees, arising out of or relating to: (1) your use of the Services; (2) your breach of these Terms; (3) any breach of your representations or warranties set forth in these Terms; (4) your violation of the rights of any third party, including intellectual property rights; or (5) any harmful act toward another user of the Services with whom you connected via the Services. We reserve the right to assume exclusive defense of any matter for which you are required to indemnify us, and you agree to cooperate with our defense of such claims.

23. Term and Termination

These Legal Terms remain in full force and effect while you use the Services. We reserve the right, at our sole discretion and without notice or liability, to deny access, suspend, or terminate your account for any reason, including violation of these Terms or any applicable law.

Upon termination, your right to use the Services ceases immediately and any unused credits are forfeited without refund. If your account is terminated, you are prohibited from registering a new account under your name, a fake name, or any third party’s name. We reserve the right to take appropriate legal action, including civil, criminal, and injunctive relief.

24. User Data

We maintain data you transmit to the Services for the purpose of managing and operating the Services. While we perform routine backups, you are solely responsible for all data you transmit or that relates to your activity on the Services. We shall have no liability for any loss or corruption of your data, and you waive any right of action against us arising from such loss or corruption.

You may opt out of marketing communications at any time by clicking the unsubscribe link in any marketing email or by contacting us at support@squarexai.com. Opting out of marketing emails will not affect essential billing or service communications.

26. Dispute Resolution

Before initiating any formal legal action, you agree to contact us at support@squarexai.com and allow 30 days for us to attempt an informal resolution. If unresolved, disputes shall be settled by binding arbitration on an individual basis. You waive any right to participate in a class action lawsuit or class-wide arbitration. Any claim must be brought within two (2) years of the date the cause of action arose, after which it is permanently barred.

Disputes involving intellectual property rights, theft, piracy, or unauthorized use are exempt from the arbitration requirement and may be brought directly in a court of competent jurisdiction.

27. Governing Law

These Terms are governed by and construed in accordance with applicable law in the jurisdiction in which SquareX AI Limited operates, without regard to any conflicts of law principles. Any disputes not resolved by arbitration shall be subject to the exclusive jurisdiction of the courts in SquareX AI Limited’s place of incorporation.

28. California Users and Residents

If you are a resident of California and have concerns regarding any unresolved issues with our Services, you may contact the appropriate consumer assistance unit as provided by the relevant state authorities.

29. Miscellaneous

These Terms constitute the entire agreement between you and SquareX AI Limited with respect to the Services and supersede all prior or contemporaneous agreements, representations, and understandings. If any provision of these Terms is found to be unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, and the remaining provisions will remain in full force and effect.

Our failure to enforce any right or provision of these Terms shall not constitute a waiver of that right or provision. We may assign our rights and obligations under these Terms at any time without notice to you. No joint venture, partnership, employment, or agency relationship exists between you and us as a result of these Terms or your use of the Services.

These Terms shall not be construed against the drafting party. Any ambiguity in these Terms shall not be resolved against us solely because we drafted them. In the event of any force majeure, including natural disasters, pandemics, governmental actions, war, civil unrest, strikes, or internet service disruptions, we shall not be liable for any failure or delay in performing our obligations under these Terms.
