Terms & Conditions

1. Acceptance of these terms

By accessing or using NWS Calc (the “Site”), you agree to these Terms & Conditions. If you do not agree, please do not use the Site. We may update these terms from time to time; the version published here, with the date above, is the one that applies.

2. What the Site is

NWS Calc is a free collection of online calculators and conversion tools. Every calculation runs locally in your browser. We do not require an account, and we do not ask for personal information to use the tools.

3. Use of the Site

You may use NWS Calc for personal and commercial purposes at no cost. You do not need permission to use a calculated result in your own work. In return, you agree not to:

• use the Site in any way that breaks the law or infringes the rights of others;
• attempt to disrupt, overload, reverse-engineer or gain unauthorised access to the Site or its infrastructure;
• scrape, copy or redistribute the Site wholesale, or present it as your own product.

4. Not professional advice

The calculators are informational tools only. Nothing on the Site is financial, investment, medical, legal, tax or engineering advice. Health calculators such as BMI are general screening aids, not diagnoses. Finance calculators use standard, simplified models that ignore fees, taxes, rounding conventions and the specific terms of any real agreement. For any decision that matters, consult a suitably qualified professional.

5. No warranty

The Site is provided on an “as is” and “as available” basis. The formulas used are standard and the working is shown where possible, but we make no warranty that any result is accurate, complete, current or fit for a particular purpose. You are responsible for checking that a result is appropriate for your use.

6. Limitation of liability

To the fullest extent permitted by law, NWS Calc, nihmathullah.com and their authors accept no liability for any loss or damage — direct, indirect or consequential — arising from your use of, or reliance on, the Site or any result it produces.

7. Third-party services and links

Some tools may rely on third-party services (for example, live exchange rates for currency conversion). The Site also links to other products in the NWS family and to external websites. We do not control third-party services or sites and are not responsible for their content, accuracy or availability. Your use of them is subject to their own terms.

8. Intellectual property

The design, branding, text and code of NWS Calc belong to nihmathullah.com. Calculated results are yours to use freely; the Site itself may not be copied or resold as a whole.

9. Availability and changes

Calculators and features may be added, changed or removed at any time, and the Site may be unavailable without notice. We may also revise these terms; continued use of the Site after a change means you accept the updated terms.
