How this platform handles your data

No account, no login, no sign-up wall. The engines run entirely in your browser, and this page states plainly what stays local, what could ever leave your device, and what analytics are designed to never collect.

No account required

Every engine works immediately, with no sign-up, no email capture, and no gated content. There is nothing to create, verify, or log into.

My Operation stays in your browser

"My Operation" is an optional feature that remembers reusable values you enter, like an hourly labor cost or a downtime cost, so future engines can offer to autofill them. This data is stored only in your browser's local storage. It is never sent to a server, never included in analytics events, and never required to use any engine. You can inspect, edit, delete, export, or import it at any time; clearing your browser data removes it completely.

Scenario sharing is explicit, never automatic

The "Share Link" feature on an engine encodes only the specific inputs you chose to share into the URL itself, with no server-side storage. No scenario is ever shared, logged, or transmitted unless you click that button.

Analytics and what it never collects

This site uses Google Analytics to understand overall traffic. It sets one first-party cookie to count visits and tell repeat visits apart. All of Google's advertising features are turned off, so no advertising cookie is ever set and your activity is never used to target ads or tracked across other websites. If you are in a region that requires opt-in consent for analytics cookies, such as the EU, UK, EEA, or Switzerland, no analytics cookie is set at all, and Google Analytics runs in a cookieless mode that counts visits without storing anything on your device. Everywhere else, the single analytics cookie is on by default. We honor Global Privacy Control (GPC) browser signals as an opt-out everywhere.

This platform's own analytics standard, separate from Google Analytics, permits only anonymous interaction events, such as which engine page was viewed or whether a calculation completed. It explicitly forbids collecting scenario inputs, calculated results, My Operation values, or any other operating data tied to your specific numbers, and Google Analytics is never sent any of that data either.

Formulas are shown, not hidden

Every engine publishes its calculation, assumptions, limitations, and sources on the same page as the result. See the methodology page for how engines are built and validated before they go live.
