Privacy Policy
Last updated: October 2026. CalcDaily is designed so your calculation inputs stay on your device.
Calculator inputs
All live arithmetic and date calculations run in your browser. We do not receive, store, or process the figures, dates, or grades you enter into calculators. Your dates stay in your browser. Choosing a country on business-day tools loads a static list of that country's holidays; inputs are not sent to our servers or put into the URL.
Site analytics
We may use privacy-oriented analytics (such as Vercel Analytics) to understand aggregate traffic and performance. These tools do not need your calculator inputs.
