Expedited Support (FAQ)
Quick answers to the most common technical and operational questions.
Are these professional tools really free for commercial use?
Absolutely. Every tool on Calculators Central is 100% free for both individual and commercial projects. We leverage non-intrusive advertising to keep our engineering high-standard and accessible.
Can I integrate your calculators into my own SaaS or Website?
We are currently developing a professional API and embed widgets scheduled for release in 2026. For now, you are welcome to link directly to our tools.
How do you ensure the precision of your financial calculators?
Our calculators are built on globally recognized mathematical and banking standards. While they provide high-precision estimates, we always recommend verifying life-critical financial decisions with a certified professional.
Is my input data processed on your servers or stored anywhere?
Privacy is our priority. Most calculators use 'Client-Side Logic,' meaning calculations happen inside your browser. We do not store, see, or transmit your individual input data.
