InstantCalc.org ("we", "us") respects your privacy. This page explains what data we collect and how it is used.
Every calculator runs entirely in your browser. The numbers you enter are never sent to our servers or stored by us.
We use Google AdSense to display ads, which keeps the site free. Google and its partners may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalised advertising by visiting Google Ads Settings. Third-party vendors, including Google, use cookies as described in Google's advertising policies.
We may use privacy-friendly analytics to understand which calculators are popular. This data is aggregated and does not identify you personally.
Most browsers let you refuse or delete cookies. Doing so will not stop the calculators from working. If you are in the EEA, UK or California, you have additional rights over your data; contact us to exercise them.
