Terms of Use

1. Acceptance of terms

By accessing or using Daily Calculator (the "site"), you agree to be bound by these Terms of Use. If you do not agree, please do not use the site. These terms apply to all visitors and to every calculator, converter and guide available on the site.

2. Scope of the service

Daily Calculator provides free, browser-based calculation tools for everyday tasks in mathematics, statistics, geometry, finance, health, dates and times, unit conversion, engineering and computing. The tools are provided for general informational purposes only.

All calculations run locally in your browser. The site does not store your inputs and does not offer any account, subscription or paid feature.

3. Estimates, not advice

Every result produced by Daily Calculator is an estimate based on the formula implemented on that page and the values you enter. Results:

• Are not offers, guarantees, quotes or contracts.
• Do not replace professional advice from a qualified practitioner in the relevant field.
• May differ from results produced by other tools that use different assumptions, rounding rules or data.

You are responsible for verifying any result that you intend to rely on for a real decision, before acting on it.

4. Financial calculators

Financial calculators (mortgage, loan, interest, investment, retirement, salary, tax and related tools) use standard formulas and simplified assumptions. They do not account for:

• Local tax laws, deductions, credits and reporting requirements.
• Lender-specific fees, insurance products, prepayment penalties or promotional rates.
• Investment fees, brokerage commissions or market volatility.
• Changes in interest rates, inflation, or regulations over the term of a product.

Financial results are illustrative only and are not financial, investment, tax or legal advice. Consult a licensed financial advisor, tax professional or attorney before making any decision with financial consequences.

5. Health calculators

Health calculators (BMI, BMR, TDEE, calorie, macronutrient, body fat, heart rate, pregnancy and related tools) provide general estimates based on published formulas. They are not diagnostic tools and are not personalised medical advice.

Health metrics such as BMI and body fat percentage are less accurate for athletes, pregnant individuals, children, older adults, and people with certain medical conditions. If you have health concerns, or before making changes to your diet, exercise or medication, consult a qualified healthcare professional.

6. Engineering and construction calculators

Engineering, electrical and construction estimators (Ohm's law, voltage drop, BTU, horsepower, gear ratio, concrete, tile, paint, roofing, stair and related tools) produce estimates based on the values you enter. Real-world outcomes depend on factors that a browser calculator cannot see, such as:

• Local building codes, electrical codes and safety standards.
• Material variability, tolerances and site conditions.
• Environmental factors (temperature, humidity, wind, altitude).
• Workmanship and installation practices.

Always verify critical values and follow applicable codes, standards and professional guidance. For projects with safety, structural or regulatory implications, consult a licensed engineer or contractor.

7. Legal and tax calculators

Calculators that touch on tax, salary, take-home pay, or similar topics use simplified models and default assumptions that may not match your jurisdiction. They are not legal, tax or accounting advice.

8. Acceptable use

You agree to use the site lawfully and in a way that does not:

• Attempt to interfere with the site's operation or availability.
• Introduce malware, attempt to exploit vulnerabilities, or bypass security controls.
• Use automated tools to scrape the site in a way that degrades performance for other users.
• Attempt to reverse-engineer the site for the purpose of building a directly competing automated clone that reuses its content without attribution.
• Use the site for anything unlawful, harmful or fraudulent.

We reserve the right to restrict or block access for behaviour that violates these terms.

9. Intellectual property

The Daily Calculator name, logo, layout, source code, written guides and calculator explanations are the property of Daily Calculator unless otherwise indicated. You may:

• Link to any page on the site from your own website, social media or documentation.

You may not republish substantial portions of the site's content or source code without prior written permission.

10. Availability and changes

The site is provided on an "as available" basis. We do not guarantee uninterrupted availability. Calculators, guides and features may be added, changed or removed at any time without notice. URLs may change; if a page moves we will make a best-effort attempt to redirect old links.

11. No warranty

To the maximum extent permitted by law, Daily Calculator is provided without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, accuracy of results, or non-infringement.

We do not warrant that any calculator will be free of errors, that results will be accurate for your specific situation, or that the site will be free of interruptions, viruses or other harmful components.

12. Limitation of liability

To the fullest extent permitted by law, Daily Calculator and its operators shall not be liable for any indirect, incidental, special, consequential or punitive damages, or any loss of profits, revenue, data or goodwill, arising out of or related to your use of the site or your reliance on any result produced by it.

Where liability cannot be excluded, it is limited to the maximum extent permitted by applicable law.

13. Governing law

These terms are governed by the laws applicable to the operator of the site. Any dispute arising out of these terms or your use of the site will be subject to the exclusive jurisdiction of the competent courts of that jurisdiction, unless mandatory local consumer law provides otherwise.
