Terms of Use
Last updated: August 24, 2026
These terms govern your use of apputil.com. By using the site you accept them. If you do not agree with any part of them, please stop using the site.
1. The service
apputil.com provides free online calculators, converters, generators and related editorial content. The service is provided as a set of static web pages; calculations run in your browser. No account, registration or payment is required.
We may add, change or remove tools and content at any time, and we may suspend the service temporarily for maintenance without prior notice.
2. Permitted use
You may use the tools freely for personal, educational and professional purposes, including using the results in your own work. You may link to any page on the site.
- Do not use automated systems to scrape or mirror the site at a rate that degrades service for others.
- Do not attempt to interfere with the operation or security of the site.
- Do not republish substantial parts of our articles or tool descriptions without written permission and attribution.
- Do not present our tools as your own product or remove attribution when embedding results.
3. No professional advice
The results produced by our calculators are informational estimates. They do not constitute medical, nutritional, financial, investment, tax, legal, engineering or any other form of professional advice, and they do not create a professional relationship of any kind.
Health calculators are screening tools, not diagnoses. Financial calculators are simplified models that ignore contract-specific fees, taxes and rate changes. Construction calculators give material estimates that must be validated by a qualified professional before purchase or execution. Always consult a qualified professional before making decisions that affect your health, your money, your legal position or anyone's safety.
4. Accuracy and availability
We take considerable care to implement documented formulas correctly and to validate them against independent references, but we cannot guarantee that every tool is free of error, nor that the site will be available without interruption. The service is provided as is and as available, without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement.
5. Limitation of liability
To the maximum extent permitted by applicable law, apputil.com and its maintainer are not liable for any direct, indirect, incidental, consequential or special damages arising from your use of the site or reliance on its results, including loss of profit, loss of data or costs incurred from decisions based on a calculation. You use the tools at your own risk and remain responsible for verifying results before acting on them.
Nothing in these terms excludes liability that cannot be excluded under the law applicable to you, including consumer rights.
6. Intellectual property
The site name, design, interface, source code and editorial text are protected by copyright and belong to their respective owners. Mathematical formulas and standards themselves are, of course, not owned by us — but our implementation, wording and presentation are.
Third-party trademarks mentioned in the tools are the property of their owners and are used only for identification.
7. Advertising and third-party links
The site displays advertising supplied by third-party networks, including Google AdSense, and may link to external websites. We do not control the content of advertisements or external sites and are not responsible for them. Any transaction you enter into with an advertiser is between you and that advertiser.
The use of cookies and similar technologies by these third parties is described in our cookie policy and privacy policy.
8. Privacy
Your use of the site is also governed by our privacy policy, which explains what data is processed, by whom, and how you control it.
9. Changes to these terms
We may update these terms as the service evolves or the law requires. The date at the top of this page always reflects the current version, and continued use of the site after a change constitutes acceptance of the updated terms.
10. Contact and applicable law
Questions about these terms can be sent to [email protected]. These terms are governed by the laws of Brazil, without prejudice to any mandatory consumer protection rules of your country of residence.
