The short version
Every calculator on this site runs entirely in your browser. Nothing you type into a calculator — prices, contract counts, risk amounts — is sent to a server, stored, or seen by us. We don't require an account, and we don't ask for your name, email, or any personal information to use any tool on this site.
Information collected automatically
Like most websites, our hosting provider (Cloudflare) automatically logs standard technical information when you visit — things like your IP address, browser type, and the pages you request. This is normal web server activity used for security and performance, not something we personally review or use to identify individual visitors.
Cookies and advertising
This site may display ads served through Google AdSense. Google and its advertising partners use cookies — including the DoubleClick DART cookie — to serve ads based on your visits to this site and other sites on the internet. This helps them show ads that are more relevant to you and limits how many times you see the same ad.
You can opt out of personalized advertising by visiting Google's Ads Settings, or opt out of third-party vendor cookies for personalized advertising by visiting aboutads.info. More detail on how Google uses data from sites that use its services is available at Google's advertising policy page.
Third-party links
Any links to outside sites (brokers, exchanges, reference material) are provided for convenience. We aren't responsible for the privacy practices or content of external sites once you leave ours.
Children's privacy
This site is not directed at children under 13, and we do not knowingly collect information from children.
