Our Mission
To provide accurate, easy-to-use, and genuinely free online tools that help people make informed decisions. Every tool on SwiftCalcTools runs entirely in your browser — your data never leaves your device.
Accuracy and Methodology
Our calculators use standard industry formulas. Finance tools use RBI-standard EMI formulas, SEBI-compliant SIP projections, and current Indian tax slabs (FY 2024-25). Health tools use WHO and Indian Council of Medical Research (ICMR) guidelines. Where relevant, we document the formula and provide a worked example on each tool page.
Privacy
All calculations happen client-side (in your browser). We do not store, log or transmit any values you enter. We use Google Analytics for aggregate, anonymised traffic measurement. See our Privacy Policy for details.
