Privacy Policy

Draft (Phase-0 skeleton) — must be reviewed and finalised before launch, in particular the advertising section, once the ad network account exists and its current privacy documentation can be linked. Last updated: 1 November 2026 (draft).

Calculator inputs

All calculators on this site run entirely in your browser. The numbers you type are not transmitted to us, not stored, and not logged. Closing the page discards them.

Information we collect

In this skeleton build, the site itself collects no personal information and sets no cookies. When the site launches with analytics and advertising, this policy will be updated to name the specific services in use before they are enabled.

Cookies

The skeleton sets no cookies. Third-party advertising (below), once enabled, typically uses cookies or similar technologies to deliver and measure ads; this section will describe them and link to the network's own policy at that time.

Third-party advertising

This site is planned to be supported by third-party advertising served by the Adsterra ad network. Ad networks may use cookies and device information to serve and measure ads, subject to their own privacy policies. The final version of this policy will link to the network's current privacy policy and describe opt-out choices before any ad code goes live.

Your choices

You can block or delete cookies in your browser settings at any time; the calculators will continue to work, because they do not depend on cookies.

Children

This site is a general-audience tool site and is not directed at children under 13.

Changes & contact

Material changes to this policy will be posted on this page with a new date. Questions: see the contact page.
