Terms of Use

Use of the site

ProjectCalcWorks provides informational calculators and supporting reference material. You may use the site for lawful personal or business planning purposes. You are responsible for the measurements, assumptions and project decisions you enter or make based on the output.

Estimates and project responsibility

Although we test formulas and try to identify variable assumptions clearly, Raúl Gea Diez does not guarantee that a calculated quantity will match a supplier order, final installation, project plan or regulatory requirement in every circumstance.

Results must be checked against current product specifications, supplier quantities, plans, site conditions and applicable local requirements before purchasing materials or carrying out work.

No professional or safety-critical advice

The calculators do not provide engineering, architectural, structural, legal, code-compliance or other licensed professional advice. Do not rely on a calculator result where a qualified professional, permit authority, manufacturer instruction or safety standard is required.

Acceptable use

You must not use the site to interfere with its operation, attempt unauthorized access, distribute malware, abuse automated requests, misrepresent the site's content as professional certification, or use the service in a way that violates applicable law.

Intellectual property

Unless otherwise stated, the original calculator interfaces, explanatory text, site structure and other original materials are provided by the operator. Third-party names, standards, documentation and linked source materials remain the property of their respective owners.

You may use calculator results for your own lawful planning. Republishing substantial parts of the site's original text, design or calculation interfaces as a competing service is not authorized unless permission is granted or applicable law permits it.

Third-party sources and links

Some pages link to manufacturers, public agencies, universities or other third parties as source references. Those organizations control their own content and may change or remove it independently. A link does not imply endorsement of every statement, product or service on the external site.

Availability and changes

We may correct formulas, update sources, change features or temporarily interrupt access for maintenance, security or technical reasons. We do not promise uninterrupted availability or that every historical result will remain reproducible after a source or calculator is updated.

Limitation of liability

To the extent permitted by applicable law, the site and its outputs are provided for informational planning purposes without a guarantee of a particular project outcome. Nothing in these terms excludes rights or liabilities that cannot lawfully be excluded.

Applicable law

These terms are administered by an operator established in Spain. Applicable mandatory consumer protections and any non-waivable rights in your jurisdiction remain unaffected.
