Calculator inputs

Calculations run locally in your browser. We do not upload inputs to a calculation API or store them in a database. Financial inputs are not saved in local storage. Assistant messages remain in memory for the current session.

Favorites and recent tools

Your browser may save calculator IDs for favorites and recently used tools. These identify tools, not your financial information. Clear them below at any time.

Shared links

A shared calculation includes its inputs in the URL. Anyone who receives it can read those inputs, and URLs may appear in browser history, server access logs, and hosting logs. Financial sharing requires an explicit checkbox. Only share information you are comfortable making visible. Related-tool transfers can also use URL parameters when you choose to carry inputs.

Hosting and analytics

The hosting provider may record standard technical request information. Vercel Web Analytics measures page visits and navigation across the site. We do not send calculator inputs, results, or assistant messages as custom analytics events. There are no advertising scripts or affiliate tracking. Review this page and applicable consent controls before introducing additional services.
