Terms of Service

1. Free Educational & Professional Access

All calculators, converters, and informational guides provided on this platform are completely free of charge for personal, academic, and professional use. No mandatory account registration, subscription fee, or payment is required to access core tools.

2. Critical Engineering & Structural Disclaimer

The calculators (including but not limited to the Footing Designer, Septic Tank Calculator, Concrete Mix Design, Quantity Takeoffs, and Steel Weight Estimator) and data provided on this website are intended strictly as preliminary design aids, educational references, and estimation guidelines.

• They do not substitute for professional engineering judgment, site-specific soil testing, or certified structural design drawings.
• While our tools adhere to standard guidelines such as the Nepal National Building Codes (NBC) and Indian Standards (IS), results must always be cross-verified and signed off by a licensed structural engineer or certified architect before physical site execution.

3. Material Market Rates & Price Tracker

Our Live Material Rate Tracker displays indicative market prices for cement, rebar, sand, aggregates, and tiles in Kathmandu. Because market conditions, supplier logistics, and fuel costs fluctuate rapidly in Nepal, these rates are for reference purposes only and should not be treated as binding commercial quotations or contractor invoices.

4. Limitation of Liability

Under no circumstances shall the creator, maintainer, or contributors of Nepal Engineering Toolbox be held liable for any direct, indirect, incidental, consequential, or structural damages (including material waste, construction budget overruns, project delays, or structural failure) arising from the use or inability to use our tools and data. You utilize all calculations and information entirely at your own risk.

5. Intellectual Property & Software Usage

The user interface design, source code structure, custom algorithms, and layout assets of this website are protected under intellectual property standards. You may not scrape, copy, or redistribute our application code for commercial reselling without explicit prior written authorization.

6. Modifications to Terms

We reserve the right to modify, update, or replace these Terms of Service at any time without prior notice. Continued use of the website following any changes constitutes your formal acceptance of the new terms.
