Example: A Brooklyn pizzeria owner types last month's food costs into a margin calculator and opens DevTools to confirm no request fires, proving the math runs client-side in the browser tab and the numbers never leave the laptop.
computation in your browser, not on a server
Computation that happens inside your browser tab, not on a server. A client-side tool takes your inputs, runs the math in JavaScript, and shows the result — without ever transmitting the inputs over the network. When the tab closes, the inputs are gone.
Why it matters
The single technical test that separates tools that can see your numbers from tools that can only show them back to you. Margin Math is client-side across all four calculators — and invites you to prove it with DevTools before typing anything sensitive.
