Privacy

This is a short policy because this site doesn't do very much with your data. Here is everything.

The calculator itself

The numbers you type into the calculator — volume, ticket size, card mix, plan terms — are never sent to a server. The arithmetic runs entirely in your browser and the results disappear when you close the tab or refresh the page.

What is stored locally

If you use the light/dark theme toggle, your choice is saved in your browser's local storage so the site remembers it on your next visit. That's the only thing this site stores on your device under its own control, and it never leaves your browser.

Advertising

This site is supported by advertising, including Google AdSense. Google and its advertising partners may use cookies or similar technology to serve ads based on your visits to this and other sites. You can review or opt out of personalised advertising through Google's own Ad Settings or at aboutads.info. This site does not control what those third parties do with that data — see Google's own privacy policy for details of how it's used.

Hosting

Like effectively all web hosting, the infrastructure serving this site may log basic technical request information — such as IP address, browser type, and the page requested — for security and reliability purposes. This site does not layer any additional analytics or tracking on top of that.

No accounts, no forms

There is no sign-up, no account, and no contact form that stores submissions in a database. If you email us, that email exists in an inbox like any other email — nothing about it is added to a marketing list.
