You agree that you will NOT engage in any of the following prohibited activities when using our Services:
Our Services are designed for individual, non-commercial use at reasonable volumes. While our calculator operates primarily within your browser and places minimal load on our servers, we reserve the right to limit or restrict access to users whose usage patterns significantly exceed typical human usage volumes, as determined in our sole discretion.

We reserve the right, but not the obligation, to monitor access to and use of our Services to detect potential violations of these Terms. In the event that we determine, in our sole discretion, that you have violated these Terms or engaged in any prohibited activity, we may take any action we deem appropriate, including but not limited to: issuing a warning, temporarily suspending your access, permanently terminating your access, blocking access from specific IP addresses or devices, reporting your activity to law enforcement or regulatory authorities, and pursuing legal action to remedy any harm caused by your actions. You acknowledge that we may cooperate with law enforcement authorities in the investigation of suspected criminal violations.
Our scientific calculator is designed and implemented with care and attention to computational accuracy. However, no computational tool, whether hardware or software, can guarantee absolute accuracy under all circumstances, and the behavior of floating-point arithmetic introduces inherent limitations. It is important that you understand the nature of our calculator, its capabilities, and its limitations.
Our scientific calculator operates primarily within your web browser using JavaScript. When you enter a mathematical expression, the expression is parsed and evaluated locally in your browser using established numerical methods. JavaScript uses the IEEE 754 double-precision floating-point standard for numerical computation, which provides approximately 15 to 17 significant digits of precision. This standard is widely used in programming languages, calculators, and computational software worldwide.
While double-precision floating-point arithmetic provides excellent accuracy for most practical purposes, it has inherent limitations that can affect results in specific scenarios. These limitations include:
Basic arithmetic operations (addition, subtraction, multiplication, and division) generally produce highly accurate results. However, users should be aware that operations involving numbers of vastly different magnitudes or operations that involve repeating decimal fractions in binary representation may produce results with tiny rounding errors. For everyday computation, these effects are typically negligible, but for scientific or engineering applications requiring the highest precision, users should verify results through alternative computational methods.
Trigonometric functions are implemented using numerical methods that provide high accuracy for typical input ranges. However, results for very large angle values may be affected by limitations in argument reduction (the process of reducing an arbitrary angle to the equivalent angle within a standard range). Additionally, certain special values (such as the tangent of exactly 90 degrees or pi/2 radians) may produce very large numbers rather than an explicit indication of undefined behavior, due to the nature of floating-point representation. Users are responsible for ensuring that they have selected the appropriate angle mode (degrees, radians, or gradians) for their computation.
Logarithmic functions (natural logarithm and base-10 logarithm) and exponential functions are implemented using standard numerical methods. Logarithms of zero or negative values are mathematically undefined and will typically produce special values (NaN or Infinity). Exponentiation of very large numbers may exceed the representable range of floating-point format. The accuracy of these functions is generally excellent for practical input ranges, but users working at the extremes of the representable range should exercise caution and verify results independently.
Factorial computation is provided for non-negative integers. Factorials grow very quickly, and the factorial of even moderately large numbers may exceed the representable range of double-precision floating-point format, producing an Infinity result. Users requiring factorials of large numbers may need to use specialized mathematical software or alternative computational approaches such as logarithmic arithmetic.
Percentage functions are provided for convenience in everyday computation. Users should be aware that percentage calculations can be interpreted in different ways depending on context, and the behavior of our percentage functions may differ from the behavior of specific calculator models or software. We recommend that users verify percentage results for critical applications, particularly in financial contexts where rounding or interpretation differences could affect financial decisions.

Without limiting the generality of the foregoing, we specifically disclaim any liability for:
In jurisdictions that do not allow the exclusion or limitation of liability for consequential or incidental damages, our total liability for all claims, losses, or damages relating to or arising from these Terms or your use of our Services, regardless of the form of action, shall in no event exceed the greater of: (a) the total amount you have paid to us, if any, for access to or use of our Services in the twelve (12) months preceding the date the claim arose, or (b) one hundred United States dollars (USD 100.00). The existence of more than one claim will not enlarge this limitation. You acknowledge and agree that the limitations of liability set forth in this section are fundamental elements of the bargain between you and us, and that we would not be able to provide our Services to you free of charge or on the terms set forth in these Terms without these limitations.
You acknowledge and agree that the limitations of liability, disclaimers of warranty, and exclusive remedies set forth in these Terms allocate risk between you and us in a reasonable and fair manner. This allocation of risk is an essential element of the basis of the bargain between you and us. These limitations will apply even if any limited remedy specified in these Terms is found to have failed of its essential purpose.
The limitations of liability set forth in this section apply not only to XinYuMaTou but also to our officers, directors, employees, agents, contractors, suppliers, licensors, partners, and affiliates, and to the benefit of all third-party service providers operating on our website. Each of these individuals and entities is an intended third-party beneficiary of these limitations of liability and may enforce these provisions against you directly.
Some jurisdictions do not allow the exclusion of implied warranties or the limitation of liability for consequential, incidental, or other damages in certain circumstances. Therefore, some of the above limitations may not apply to you in their entirety. In such jurisdictions, these limitations shall apply to the fullest extent permitted by the law of that jurisdiction. The rights granted to you in these Terms are in addition to other rights and remedies you may have under applicable law.
You agree to defend, indemnify, and hold harmless XinYuMaTou, our officers, directors, employees, agents, contractors, suppliers, licensors, partners, and affiliates, from and against any and all claims, damages, losses, liabilities, costs, debts, and expenses (including but not limited to reasonable attorneys' fees and litigation expenses) arising from or relating to:
This indemnification obligation applies to all losses, damages, and costs of every kind and nature, known and unknown, suspected and unsuspected, disclosed and undisclosed, arising out of or in any way connected with the matters described above. This indemnification obligation applies without regard to any negligence or alleged negligence on the part of any party indemnified hereunder, except to the extent that such negligence constitutes gross negligence or willful misconduct.
We reserve the right, at our own expense, to assume the exclusive defense and control of any matter otherwise subject to indemnification by you. In such event, you will have no obligation to defend us in that matter, but you will remain responsible for any damages or costs ultimately found to be subject to indemnification. You agree not to settle any such matter without our prior written consent, which will not be unreasonably withheld, conditioned, or delayed. We may, in our sole discretion, participate in the defense of any claim with counsel of our own choosing at our own expense. You agree to cooperate fully with us in the defense of any such claim, including but not limited to providing reasonable assistance and information at our request.
The indemnification obligations set forth in this section shall survive any termination or expiration of these Terms or your use of our Services. They shall remain in full force and effect for the benefit of XinYuMaTou and the other indemnified parties described above, regardless of any change in circumstances or any termination or cessation of your use of our Services.
We may update, revise, or modify these Terms of Service from time to time to reflect changes to our practices, to clarify our terms, to adapt to new features or capabilities of our calculator, or to comply with legal and regulatory requirements. When we make changes to these Terms, we will update the "Effective Date" and "Last Updated" date at the top of this page. In cases where changes are material or significant, we may also provide additional notice of changes through a notice on our website homepage, through a banner notification, or by other reasonable means. What constitutes a "material" change will be determined in our sole discretion, but generally includes changes that affect your rights or obligations under these Terms in a significant way.
Your continued use of our Services after the effective date of any changes to these Terms constitutes your acceptance of the revised Terms. If you do not agree to the revised Terms, you must discontinue your use of our Services immediately. We encourage you to review these Terms periodically to stay informed about the terms governing your use of our Services. You can determine when these Terms were last revised by referring to the "Last Updated" date at the top of this page.
Previous versions of our Terms of Service are available by contacting us. Upon reasonable request, we will provide you with access to archived versions of prior Terms for your reference. Please note that prior versions are provided for historical reference only and do not govern your current use of our Services. The most recent version of these Terms, as posted on our website, always governs your current use of our Services.
We also reserve the right to modify, suspend, or discontinue our Services or any portion of our Services at any time, with or without prior notice. This includes the right to add or remove calculator functions, update or change the user interface or visual design, modify the behavior or presentation of existing functions, limit the availability of certain features, or perform maintenance activities that may temporarily affect availability. We will not be liable to you or any third party for any modification, suspension, or discontinuance of our Services or any portion thereof.
We may, from time to time, develop new features, functions, or capabilities for our scientific calculator. The introduction of new features, even if announced or described in advance, does not create any obligation on our part to continue providing such features, nor does it create any warranty or guarantee regarding their availability, functionality, or accuracy. We may modify, discontinue, or change any new features at any time without notice.
We reserve the right to terminate or restrict access to our Services for any user who violates these Terms or engages in activities that we determine, in our sole discretion, are harmful to our Services, other users, third parties, or our interests. We may take such action without prior notice and without liability to the user. Following any such termination or restriction, the user must cease all use of our Services and must not attempt to access or use our Services through alternative means, accounts, or devices. The provisions of these Terms that by their nature should survive termination shall survive any termination of access, including but not limited to provisions regarding intellectual property rights, disclaimers of warranty, limitations of liability, indemnification, and governing law.
These Terms and your use of our Services shall be governed by and construed in accordance with the laws of the jurisdiction where our primary operations are based, without regard to its conflict of law principles. For the avoidance of doubt, the United Nations Convention on Contracts for the International Sale of Goods (CISG) shall not apply to these Terms or to your use of our Services. Any and all access to and use of our Services is deemed to take place in the jurisdiction where our primary operations are based, regardless of the location from which you access our Services.
Before initiating any formal dispute resolution process, we encourage you to first attempt to resolve any dispute, claim, or controversy arising from or relating to these Terms or your use of our Services through informal negotiation. You may initiate informal negotiation by contacting us through the contact information provided later in this policy. We will use reasonable efforts to respond to your concern and to attempt to resolve the dispute through good faith negotiation. Similarly, if we have a dispute with you, we will attempt to contact you using the contact information you have provided to us, if any.
If the dispute cannot be resolved through direct negotiation within a reasonable period (not to exceed thirty (30) days from the date of initial contact), either party may proceed to formal dispute resolution as described below. We believe that informal resolution is preferable to formal legal proceedings, and we are committed to addressing legitimate user concerns in a fair and reasonable manner.
If informal resolution is not successful, any dispute, claim, or controversy arising out of or relating to these Terms or your use of our Services shall be resolved by binding arbitration administered by a reputable international arbitration institution according to its applicable rules. The arbitration shall be conducted in the English language, unless otherwise agreed by both parties in writing. The arbitrator shall be selected according to the rules of the chosen arbitration institution, and the decision of the arbitrator shall be final and binding on both parties and may be entered as a judgment in any court of competent jurisdiction. The allocation of arbitration costs between the parties shall be determined by the arbitrator in accordance with applicable rules and law.
Alternatively, and without limiting the foregoing, either party may bring any dispute, claim, or controversy in the appropriate courts of the jurisdiction where our primary operations are based, and you consent to the personal jurisdiction and venue of such courts for the purpose of litigating any such claim or dispute.
Nothing in this section shall prevent us from seeking injunctive or other equitable relief in any court of competent jurisdiction to protect our intellectual property rights, to prevent unauthorized access to or use of our Services, or to enforce the terms of these Terms. You acknowledge and agree that a breach or threatened breach of these Terms by you in connection with our intellectual property rights or our security interests could cause immediate and irreparable harm for which monetary damages would be inadequate, and you therefore consent to the granting of injunctive or other equitable relief in such cases without the requirement of posting a bond or proving actual damages.
To the fullest extent permitted by applicable law, you agree that any dispute, claim, or controversy arising out of or relating to these Terms or your use of our Services shall be brought solely in your individual capacity and not as a plaintiff or class member in any purported class action, representative action, or collective action. Unless both you and us expressly agree otherwise in writing, the arbitrator or court may not consolidate more than one person's claims and may not otherwise preside over any form of class, representative, or collective proceeding. If this specific provision is found to be unenforceable, then the entirety of the dispute resolution provisions of this section shall be deemed null and void, and the dispute shall be resolved exclusively by the courts described above.
If any provision of these Terms is deemed unlawful, void, or unenforceable for any reason, that provision shall be deemed severable from these Terms and shall not affect the validity and enforceability of any remaining provisions. The unenforceable provision shall be interpreted and applied as closely as possible to reflect the original intent of the parties, and a valid and enforceable provision that achieves the same or similar objective may be substituted in its place. The remaining provisions of these Terms shall continue in full force and effect. If any essential provision of these Terms is found to be unenforceable, the remaining provisions shall continue to apply to the maximum extent permitted by law.
You agree that regardless of any statute or law to the contrary, any claim or cause of action arising out of or related to use of our Services or these Terms must be filed within one (1) year after such claim or cause of action arose, or forever be barred. This limitation applies to you and to us equally.
