Cookie Policy
Last updated: August 2026
This Cookie Policy explains what cookies are, which ones this site may use, and how you can control them.
What Are Cookies?
Cookies are small text files stored on your device by your browser when you visit a website. They help sites remember information about your visit, such as preferences or, in some cases, help site owners understand how the site is used.
Cookies This Site May Use
| Type | Purpose | Status |
|---|---|---|
| Necessary | Basic site functionality, such as remembering your cookie consent choice. | May be used |
| Analytics | Understanding how visitors use the site, to help us improve it (e.g. Google Analytics). | [Update once confirmed] |
| Advertising | Showing relevant ads through a third-party ad network (e.g. Google AdSense). | [Update once confirmed] |
The calculator itself does not use cookies to store or transmit the values you enter — those calculations happen entirely in your browser and are never sent to our servers.
Necessary Cookies
These are cookies required for the site to function properly, such as remembering that you’ve responded to a cookie consent notice. Without these, some basic features may not work as expected.
Analytics Cookies
If enabled, analytics cookies help us understand aggregate visitor behaviour (such as which pages are visited and how often) so we can improve the site. [This section will be updated to name the specific analytics service in use, once one is added, along with a link to its own privacy policy.]
Advertising Cookies
If enabled, advertising cookies may be set by third-party ad networks to show relevant ads and measure ad performance. [This section will be updated to name the specific ad network(s) in use, once added.] These third parties may have their own cookie and privacy policies, which we encourage you to review.
How to Control Cookies
Most browsers let you view, manage, delete, and block cookies through their settings. You can also use your browser’s private/incognito mode to browse without storing cookies. Note that blocking some cookies may affect how parts of the site function.
Changes to This Policy
We may update this Cookie Policy as the site’s use of cookies changes, for example if we add or remove analytics or advertising services. The “Last updated” date at the top reflects the most recent revision.
