Calculation inputs

Numbers entered into these calculators are processed only in your browser and are not sent anywhere by this tool. There is no calculation backend, account, or persistent browser storage for inputs.

Page URLs and sharing

The calculators keep editable inputs in the page URL hash as you change them. Those inputs appear in the link when you use Copy link. The hash is not sent to the server in a page request, but anyone with the complete link can read the figures. URLs may also remain in browser history or be visible to browser extensions.

Copy link asks the browser to write that URL to your clipboard. If automatic copying is unavailable, the tool displays the link for manual copying. Avoid sharing confidential numbers. ROAS Reset clears numeric inputs; Break-Even Reset restores example inputs. Both clear the current page hash, but neither erases previously shared links, clipboard contents, or browser history.

Technical page requests

The web host may process standard technical data, such as your IP address, browser type, and requested page, to serve pages. A local preview server may also log page requests. Calculation inputs in URL hashes are not included in those requests.
