Terms and Conditions
Last updated:
These terms apply to your use of Calculator and its tools and content. The website is owned and operated by Satyajit Debnath. By using the website, you agree to these terms to the extent permitted by applicable law. If you do not agree, stop using the website. Questions may be sent to iamsatyajitdebnath@gmail.com.
Purpose of the service
Calculator provides general calculation tools and explanatory information. Results are generated from your inputs, formulas, and stated assumptions. The website does not provide individualized professional advice or establish an adviser, clinician, engineer, or other professional relationship.
Your responsibility for inputs and results
Health calculators are educational estimates, not medical devices or diagnosis tools. Adult formulas and ranges may be unsuitable for children, pregnancy, athletes, or people with particular health conditions. A sleep-cycle estimate cannot determine sleep quality, a pulse count cannot diagnose a heart rhythm, and a calorie estimate is not an individual treatment or nutrition plan.
Check that inputs are complete, accurate, and expressed in the required units. Review the formula, assumptions, rounding, and limitations shown on the page. Estimates can vary from actual outcomes because of local conditions, measurement errors, rates, fees, changing rules, or other factors not included in the calculation.
Verify important results independently. Financial and tax tools do not replace advice from a qualified adviser; health tools do not diagnose or treat a condition; material estimates do not replace a site inspection, structural assessment, or professional design. Contact a suitable professional before using a result for a consequential decision.
Reference data and conversion rates
Some conversions use fixed factors or indicative data. External reference rates may change, be delayed, or be unavailable. A currency result is not an offer to exchange money and may differ from bank, card, or transaction rates. Any displayed date, source, or limitation forms part of the information you should consider.
Acceptable use
Use the website lawfully. Do not attempt to compromise its security, disrupt availability, introduce malicious code, impersonate another person, or misuse someone else's personal information. Automated access must not overload the service or bypass access restrictions. We may restrict access where reasonably needed to protect the service or respond to misuse.
Content and intellectual property
Website text, software, designs, and other material may be protected by copyright or other rights. You may use calculators for personal or professional calculations and retain your own results. That permission does not grant rights to republish the site's articles, branding, or software. Third-party material remains subject to its owner's rights and any applicable licence. Contact us about permissions or a rights concern.
External services and advertising
Links, reference services, and any advertisements may lead to providers with separate terms and privacy policies. We do not control their services or guarantee their information, availability, products, or offers. An advertisement or external link does not by itself constitute an endorsement. Resolve purchases and provider-specific issues with the relevant third party.
Availability and changes
We may correct, update, replace, or remove tools and content. Features can be interrupted by maintenance, browser differences, network failures, or unavailable external services. Saved browser history is not a backup service; export or record information you need to keep.
Disclaimer and liability
To the extent permitted by law, the website is provided as available without a guarantee of uninterrupted operation, complete accuracy, or suitability for a particular purpose. We are not responsible for losses arising from incorrect inputs, unverified reliance on estimates, unavailable services, or third-party conduct to the extent applicable law permits that limitation.
These terms do not exclude or limit any responsibility or statutory rights that cannot lawfully be excluded or limited. Applicable consumer protections remain in effect.
Privacy, updates, and contact
Read our Privacy Policy and Cookies Policy for information handling and browser storage. Revised terms will be posted here with an updated revision date. Email iamsatyajitdebnath@gmail.com with a question or to report a problem.
