Calculator inputs
Calculator code runs in your browser. It does not transmit the numbers you enter to a StackOutlay server, save them to an account or keep them in browser storage. Refreshing the page resets the example inputs. Printing or saving a PDF is handled by your browser.
Analytics and accounts
This edition does not include an operator-installed analytics script, advertising pixel, contact form or newsletter signup. Hosting and access-control services may process connection details and use their own session mechanisms; this page does not describe or override their policies.
External provider links
When you follow an external link, the destination's privacy policy applies. If paid referral links are enabled in a later edition, the destination or affiliate network may use tracking for attribution. The link status is described on the disclosure page.
Changes
Last updated: 29 October 2026. If analytics, forms or commercial tracking are added, this notice must be revised before those features are launched.
