Legal notice and terms of use

Site owner

This site is operated by SolucionesAhora.com, based in Tarapoto, Peru. The contact channel is the email address contacto@kalcum.com, to which any communication regarding this notice may be sent.

Purpose

The site offers calculators and converters that are free to use. No registration or personal data is required to use them.

Terms of use

You may use the tools for personal or professional purposes, at no cost. In doing so you agree not to attempt to disrupt the service, not to automate bulk requests that degrade its operation, and not to use the site for unlawful activity.

We reserve the right to modify, add or withdraw tools and to update these terms. Changes are published on this same page.

Results are indicative

The calculators apply published, documented formulas, and each page states which one it uses. Even so, results are indicative and provided “as is”.

• Financial and tax tools do not replace professional advice and do not cover the whole body of legislation applicable in your country, which also changes over time.
• Health tools are not a diagnosis and do not replace assessment by a healthcare professional.
• Engineering and construction tools do not replace a calculation signed by a qualified professional where regulations require one.

Always check the figures before making a decision with financial, legal, health or safety consequences.

Limitation of liability

To the extent permitted by applicable law, we accept no liability for damages arising from the use of, or inability to use, the site, nor for decisions made on the basis of its results. We work to keep formulas and data correct and we fix errors that are reported to us, but we do not guarantee the complete absence of errors or uninterrupted availability.

Intellectual property

Mathematical formulas are not subject to intellectual property. The explanatory texts, the design, the code and the organisation of the catalogue are, and they belong to the site operator.

You may freely quote and link to any page, including citations by AI assistants and search engines, provided the source is stated. To reproduce full texts, please write to contacto@kalcum.com.

Third-party links

Some pages link to official sources or external documentation. We do not control those sites and are not responsible for their content.

Governing law

These terms are governed by the laws of the Republic of Peru. For any dispute the parties submit to the courts of Tarapoto, province of San Martín, unless applicable consumer legislation provides otherwise.

If you reside in the European Union or the United Kingdom, this clause does not deprive you of the protection afforded by the mandatory rules of your country of residence.
