Terms of Service

Last updated: 2026-11-03

Welcome to ToolDune. By accessing or using this website (tooldune.com) and any of its online tools, calculators, converters, or reference materials, you agree to comply with and be bound by these Terms of Service. If you do not agree to these terms, please do not use the site.

1. Description of Service & Client-Side Architecture

ToolDune provides a collection of web-based utilities and calculators designed to perform mathematical, unit conversion, date calculation, text manipulation, and informational tasks. Every tool is architected to run entirely in your web browser using client-side JavaScript. The values, numbers, text, and files you input into any tool on this site remain on your local device and are never transmitted to our servers, logged, or stored.

2. Informational & Educational Purpose Only (No Professional Advice)

All calculations, conversions, estimators, reference charts, and guidance provided on ToolDune are for informational, educational, and general reference purposes only.

• Financial & Tax: Financial calculators (such as loan payoff, simple interest, rent split, capital gains, tax loss harvesting, or retirement estimations) do not constitute licensed financial, investment, accounting, or tax advice. Financial regulations and tax laws vary widely by jurisdiction and change frequently. Always consult a Certified Public Accountant (CPA), licensed financial advisor, or qualified tax professional before making significant financial commitments.
• Legal & Contracts: Tools such as number-to-words converters or date calculators do not provide formal legal documentation or legal advice. Consult an attorney for contract drafting and formal legal determinations.
• Engineering & Construction: Calculators relating to lumber sizes, drill bits, pipe dimensions, circuit loads, or structural measurements are reference approximations. Always refer to local building codes, manufacturer specifications, and licensed structural engineers or master electricians for construction and electrical work.
• Health & Medical: Any tools referencing hydration, sleep, nutrition, or physical vitals are general estimates and never substitute for professional medical advice, diagnosis, or clinical treatment from a licensed physician.

3. Disclaimer of Warranties

ToolDune is provided on an "as is" and "as available" basis, without warranties of any kind, whether express, implied, statutory, or otherwise. While we strive for arithmetical precision, verify formulas against authoritative standards (such as NIST, ISO, IRS publications, and mathematical literature), and test tools regularly with automated test suites, we make no representations or warranties that:

• The tools, results, or data tables will be completely error-free, uninterrupted, or timely;
• The formulas or external constants reflect recent statutory amendments prior to our scheduled updates;
• The results will meet your specific personal, commercial, or operational requirements.

4. Limitation of Liability

To the fullest extent permitted by applicable law, ToolDune, its operators, contributors, and affiliates shall not be liable for any direct, indirect, incidental, consequential, special, punitive, or exemplary damages arising out of or in connection with your use of, or inability to use, this website or reliance on any calculations or information provided herein. This includes, without limitation, loss of profits, financial penalties, business interruption, loss of data, or construction errors, even if advised of the possibility of such damages.

5. Acceptable Use & User Conduct

You agree to use ToolDune solely for lawful purposes. You agree not to:

• Engage in automated scraping, denial-of-service attacks, or excessive hammering that interferes with site availability or edge worker performance;
• Attempt to bypass any security controls, WAF protections, or rate limits deployed on our edge infrastructure;
• Probe, scan, or test the vulnerability of the site or its associated workers;
• Use the site to transmit malicious code, worms, or viruses.

6. Intellectual Property

The ToolDune name, logo, site architecture, layout, design, custom CSS, tool logic, and written editorial content are protected by copyright, trademark, and intellectual property laws. You may freely use the calculations and output produced by the tools for your personal or commercial projects. However, you may not systematically duplicate, mirror, scrape, or redistribute the site's complete codebase, design, or proprietary assets without prior written consent.

7. Third-Party Links & Advertising

ToolDune may display third-party advertisements (such as Google AdSense) to keep our tools free and accessible. Third-party advertising vendors may use cookies to serve ads based on your visit to this site and other sites on the internet. You can learn more and manage personalized ad preferences by reviewing our Privacy Policy.

Our pages may also provide outbound hyperlinks to official government portals, standards organizations (such as NIST, ISO, or DOL), and reference sources. We have no control over the content, privacy practices, or availability of third-party websites.

8. Privacy Policy Integration

Your privacy is fundamental to our architecture. Please review our Privacy Policy, which details how local storage is used exclusively for theme preferences and confirms our strict policy of never harvesting, logging, or storing your calculation inputs.

9. Changes to These Terms

We reserve the right to revise or update these Terms of Service at any time. When changes are made, the "Last updated" date at the top of this page will be revised accordingly. Your continued use of ToolDune following any changes constitutes acceptance of the updated terms.
