Frequently Asked Questions
Everything you need to know about ToolZoneX.
Yes! All the tools and calculators on ToolZoneX are 100% free to use. There are no paywalls, hidden charges, or premium subscriptions required.
No. Calculations happen in your web browser, so your salary, loan amounts and health numbers aren't sent to us or stored by us. A few tools that need live data — exchange rates, IP lookup and PDF translation — contact an outside service and say so on the page. Our Privacy Policy lists them.
We use standard, published formulas and rates, and fix errors as soon as they're reported. Results are still estimates for information and education: rules and rates change, and your situation may differ. For tax filing, investments or medical decisions, check with a qualified professional or the official source.
Research, including a WHO expert consultation, has found that South Asians face higher metabolic risk at lower body weights. Indian clinical guidelines therefore treat a BMI of 23 or more as overweight for adults, rather than the international 25. BMI is a screening measure, not a diagnosis — talk to a doctor about your own health.
