Terms of Service

1. Acceptance of These Terms

Welcome to Jerusalen Tools. These terms of service govern your access to this website and your use of all the calculators and tools it provides. By accessing the site or using any of its tools, you confirm that you have read these terms and agree to be bound by them. If you do not agree with any part of these terms, please do not use the site.

Effective date: 11 June 2026.

2. Description of the Service

Jerusalen Tools is a platform of free online calculators provided for educational and informational purposes only. Our tools cover areas such as finance, health, mathematics and unit conversion.

All calculators run entirely in your browser (client-side processing): the data you enter is never sent to our servers and does not leave your device while a calculation is performed.

The service is free of charge and requires no registration. We may add, change or remove tools at any time without prior notice.

3. Use at Your Own Risk

You use this website and its calculators entirely at your own risk.

The results produced by our tools are educational estimates for informational purposes only and do not constitute financial, tax, medical, legal or any other form of professional advice. In particular:

  • Health calculators: results such as body mass index, calorie needs or other indicators are approximate guides only. They are no substitute for the diagnosis, advice or treatment of a qualified healthcare professional. Always consult your doctor before making decisions that affect your health.
  • Finance and tax calculators: results such as loan repayments, interest, net salary or tax figures are approximations based on general formulas and may not reflect your personal circumstances or the rules in force in your jurisdiction. Speak to a qualified financial or tax adviser before making financial decisions.

You alone are responsible for verifying any result and for any decision you make based on it.

4. No Warranty

The service is provided “as is” and “as available”. Although we work to keep our formulas and content accurate and up to date, we make no warranty as to the accuracy, completeness or currency of any result, nor that the site will be available without interruption or free of errors. Tax, financial and health-related rules change frequently and vary between countries and regions.

5. Intellectual Property

Unless otherwise stated, the content of this website — including text, design, logos, source code, structure and the selection of content — is owned by Jerusalen Tools or its licensors and is protected by intellectual property law.

You may use the tools for personal, non-commercial purposes. Reproducing, distributing, publicly communicating or adapting the content for commercial purposes without our prior written consent is not permitted. Bulk scraping, reverse engineering for the purpose of copying, and any use that may impair the operation of the site are also prohibited.

6. Advertising, Third-Party Links and Affiliates

This website may display advertising served by third parties, such as Google AdSense, and may contain links to external websites. We have no control over those sites or their content and accept no responsibility for them. A link does not imply any recommendation or endorsement.

Affiliate disclosure: some links may be affiliate links. This means that if you make a purchase through them, we may earn a commission at no extra cost to you. This potential income never influences calculator results or editorial content.

7. Limitation of Liability

To the fullest extent permitted by applicable law, Jerusalen Tools shall not be liable for any direct or indirect loss or damage arising from the use of, or inability to use, the site or its tools, including loss resulting from decisions made on the basis of calculator results.

Nothing in these terms excludes or limits any liability that cannot be excluded or limited under applicable law, nor does it affect any mandatory rights you hold under consumer protection legislation.

8. Changes to These Terms

We may update these terms at any time to reflect legal, technical or service-related changes. The current version, together with its update date, will always be published on this page. Continued use of the site after changes are published constitutes acceptance of the updated terms; where changes are material, we will make reasonable efforts to highlight them.

9. Governing Law

These terms are governed by Spanish law and by any applicable European Union legislation. Any dispute will be brought before the courts having jurisdiction under the law; if you act as a consumer, you may bring proceedings before the courts of your place of residence. Consumers residing in the EU may also use the European online dispute resolution platform.
