Terms of Use

Acceptable use

You may use the site for lawful personal or business work. Do not use it to break the law, harm other people, interfere with the site, probe its security, distribute malicious code, or place an unreasonable automated load on its services.

Results and professional advice

Tool results are practical calculations, transformations, or estimates based on the information you provide and the assumptions stated on each page. You are responsible for checking inputs, units, formulas, local rules, product instructions, and final decisions.

WebUtilsLab does not provide engineering, legal, tax, financial, medical, or safety advice. A result does not replace a qualified professional or a project-specific review. To the extent permitted by law, the site is provided without a guarantee that every result will be complete, error-free, or suitable for a particular purpose.

Intellectual property

The site's original text, design, and code belong to the operator unless a page or included licence says otherwise. Product names and third-party materials belong to their respective owners. You keep any rights you already have in information you enter, and WebUtilsLab does not claim ownership of tool inputs or outputs created from them.

External links

Links to other websites are provided for reference or convenience. Those websites control their own content, availability, terms, and privacy practices. A link does not by itself mean that WebUtilsLab endorses or is affiliated with the external service.

Changes and availability

Tools, content, and these terms may be corrected, updated, suspended, or removed. Material changes to these terms take effect when the revised version is published with a new effective date. Continued use after that date means you accept the revised terms.

Governing law

These terms are governed by the laws of the People's Republic of China, without depriving a consumer of any mandatory protection that applies in the consumer's place of residence.

Operator and contact

The operator is identified in the Legal Notice. Questions about these terms can be sent through the public address on the Contact page.
