Terms of Service & Professional Disclaimers
Please read these terms carefully before utilizing Calculas tools, embedding widgets, or exporting reports.
Critical Category Disclaimers (YMYL)
Financial & Tax
Calculators are for educational modeling only. Not licensed financial, tax, or legal advice. Always consult a certified CPA or qualified financial planner before signing loan agreements or filing taxes.
Health & Fitness
Biometric projections (BMI, BMR, TDEE, body fat) are statistical population estimations. Never substitute calculations for professional medical diagnosis or personalized dietary therapy.
Engineering & Building
Construction, area, and material volume calculators are estimations. Actual project requirements must be validated against local municipal building codes and certified structural engineers.
1. Acceptance of Terms
By accessing or using Calculas (calculas.co), embedding calculator widgets into third-party websites, or downloading compiled reports, you agree to be bound by these Terms of Service. If you do not agree with any provision, please discontinue using the service immediately.
2. Free Embed & Widget Distribution License
Calculas permits and encourages web publishers, educators, students, and businesses to embed our calculator tools via iframe (/embed/[category]/[slug]) free of charge, subject to the following condition:
- You must preserve the subtle “Calculas” attribution link rendered within the widget header.
- You may not misrepresent the calculators as your own proprietary calculations or remove copyright notices.
3. Mathematical Precision & Estimation Nature
While Calculas conducts automated unit testing and adheres to IEEE 754 precision standards and published governmental formulas, real-world variables (such as localized municipal tax adjustments, lender-specific amortization quirks, and individual medical factors) can alter real-life outcomes. All results are provided “as is” without representation of commercial warranty.
4. Limitation of Liability
In no event shall Calculas, its authors, or contributors be held liable for any direct, indirect, incidental, consequential, special, or punitive damages arising from the use of, or inability to use, any calculator, calculation result, or downloaded PDF/Excel export.
5. Acceptable Use
You agree not to engage in malicious attacks, distributed denial-of-service attempts, or reverse engineering intended to compromise the infrastructure of Calculas. Crawling and programmatic consumption for AI indexing are welcome via our published llms.txt and OpenAPI specification.
