Privacy Policy

Calculator inputs stay in the browser and are not submitted to a server by the calculator engine. We do not request bank credentials, financial-account access or account signup. Theme and display-currency choices may be saved in local browser storage. Scenarios remain in the current tab’s memory.

A copied scenario link contains input values in its URL fragment; anyone you share it with can read them. Your web server can retain ordinary access logs such as IP address and requested path. Ko-fi is an external service governed by its own policy. External advertising and analytics scripts are disabled in this release unless the owner supplies and approves their exact integration. Any activation requires an updated disclosure and appropriate consent controls.

Policy updated: 14 October 2026.
