Acceptance and operator
These OnlineCalculator.xyz terms of use are effective August 29, 2026. They govern the public directory, calculators, text, artwork, and related pages. The service is operated by OnlineCalculator.xyz, 30 N Gould St Ste R, Sheridan, WY 82801, USA. By accessing or using the service, you agree to these terms. If you do not agree, do not use it.
Users must be at least 16 years old. Mandatory local rules may impose a higher age or require authorization. The service has no account, subscription, payment, professional engagement, or promise to retain a calculation.
Informational mathematics
The calculators apply displayed formulas to values supplied by the visitor. They are informational mathematical aids, not medical, legal, financial, tax, investment, insurance, accounting, engineering, construction, employment, education, safety, or purchasing advice. No result is an official record, professional opinion, product certification, grade, quotation, or guarantee.
Correct arithmetic does not establish that a formula models a real situation. Inputs can be incomplete, units can be inconsistent, and outside rules can control an answer. Browser floating-point limits, guarded ranges, rounding, and software defects can affect outputs. Verify important results independently and consult an appropriate authority or professional when consequences matter.
Limited permission
OnlineCalculator.xyz grants a limited, revocable, non-exclusive, non-transferable permission to use the public site for lawful personal or internal informational purposes while these terms are followed. You may copy your own result summary, including relevant units and assumptions.
You may not disrupt or overload the site; probe or bypass security; access non-public data; introduce malicious code; use the service unlawfully or to violate rights; misrepresent an output as certification; remove ownership notices; reproduce substantial original content or interface for a competing product; or scrape in a manner that harms availability. Published crawler controls and applicable law remain relevant.
Do not place credentials, government identifiers, health facts, account records, another person’s private information, unlawful content, or confidential material in optional text fields or support messages. The site does not need them to perform elementary calculations.
Inputs, feedback, and copied results
You remain responsible for input accuracy, rights, units, interpretation, and how a result is used. The application is designed not to claim ownership of raw numeric values or short calculator labels. It also does not save them in a cloud history.
When you copy, print, save, or send a result through another service, that destination controls the new copy. Retain the input roles, formula, units, and rounding if another person must understand it.
Feedback and calculator proposals sent by email may be used to evaluate and improve the site without an obligation to publish, pay, maintain confidentiality, or assign ownership, unless a separate signed agreement states otherwise. Do not submit proprietary methods or material you cannot authorize.
Site intellectual property
The OnlineCalculator.xyz brand, original copy, original artwork, interface, catalog organization, and software belong to OnlineCalculator.xyz or its licensors and can be protected by intellectual-property law. Mathematical facts, standard unit definitions, and ordinary formulas may not themselves be owned, but this site’s original expression, code, selection, and arrangement can be.
Third-party names and standards remain the property of their owners. Descriptive reference does not imply affiliation, endorsement, or a license to use another party’s branding. These terms grant no right to present another product as OnlineCalculator.xyz or as sponsored by the operator.
Availability and modification
The operator may correct, change, suspend, or discontinue a page, calculator, route, formula convention, or the entire service. Availability, compatibility with every browser, retention of inputs, future tools, and a response deadline are not promised. Keep the values and method needed to reproduce any result you rely upon.
Updates may be necessary to fix a defect, clarify a formula, narrow a domain, or reflect law and infrastructure. A prior output is not guaranteed to be reproduced after a disclosed method changes.
Disclaimers
To the fullest extent allowed by law, the service is provided “as is” and “as available.” OnlineCalculator.xyz disclaims warranties of accuracy, completeness, merchantability, fitness for a particular purpose, title, non-infringement, availability, and error-free operation where those warranties may lawfully be disclaimed. Rights and warranties that cannot legally be excluded remain unaffected.
Worked examples are simplified. Directory matches are deterministic tag matches, not professional recommendations. Unit conversions depend on the selected definition and supported family. Geometry uses idealized dimensions. Statistics describe entered values without validating sampling or interpretation.
Liability limits
To the fullest extent permitted by law, OnlineCalculator.xyz and its officers, employees, contractors, licensors, and service providers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive loss, or for lost revenue, profit, data, opportunity, goodwill, or expected savings connected with the service.
Where liability cannot be excluded, total liability will be limited to the greater of the amount paid to OnlineCalculator.xyz for the service in the twelve months before the event or USD 100. The service is free. Some jurisdictions do not allow certain limits; a limit applies only to the lawful extent and never excludes liability that cannot be limited.
Misuse responsibility
To the extent allowed by law, you are responsible for claims and reasonable losses arising from your unlawful misuse, violation of these terms, or infringement of another person’s rights. A consumer is not required to indemnify the operator where applicable law prohibits it.
Law, resolution, and general provisions
Applicable laws of the United States of America govern these terms, excluding conflict-of-law rules, while mandatory consumer protections remain applicable. Before a formal claim, the parties should try in good faith to resolve it through support@onlinecalculator.xyz. A court proceeding belongs in a court with valid jurisdiction, subject to rights that cannot be waived.
If a provision is unenforceable, it will be limited or severed only as needed; the remainder continues. Failure to enforce is not a waiver. These terms, the Privacy Policy, and Cookie Policy form the public service agreement unless a signed agreement applies. Headings assist reading and do not alter meaning.
Frequently asked questions
Are calculator results warranted to be correct?
No. Pages state intended formulas and controls, but inputs, software defects, rounding, and model choice can still produce an error or unsuitable result.
May I cite a result?
You may copy your result, but include the method and independently verify material work. The site does not certify it.
Can these terms change?
Yes. A revised page will display a new effective date, with material notice when law requires it.
Where can I raise an issue?
Email support@onlinecalculator.xyz with one route and a non-sensitive reproducible example after reading the Privacy Policy.
Use a calculator only after confirming that its labeled inputs, formula, domain, and units match the problem you intend to solve.
