What Are Cookies?

Cookies are small text files stored on your device when you visit a website. They can help websites remember settings, measure traffic, improve performance, and support features such as analytics or advertising.

How We Use Cookies

Our calculators are designed to work without requiring you to create an account. The website uses cookies or similar technologies for essential website operation, analytics, performance monitoring, security, preference storage and advertising.

Types of Cookies We May Use

Essential cookies: These support basic website functionality, security, and page delivery.

Analytics cookies: These help us understand page visits, calculator usage, device types, and general traffic patterns so we can improve the website.

Preference cookies: These may remember choices such as settings, calculator options, or interface preferences if we add those features.

Advertising or affiliate cookies: These may be used if the website later displays ads, sponsored placements, or affiliate links.

Third-Party Cookies

Third-party services such as analytics, embedded content, advertising networks, or security tools may set cookies according to their own policies. We do not control every third-party cookie after you interact with external services.

Google AdSense and Advertising Cookies

This website uses Google AdSense to display advertising. Google is a third-party vendor that uses cookies to serve ads on this site.

Google's use of advertising cookies, including the DoubleClick cookie, enables Google and its partners to serve ads to you based on your visit to this site and other sites on the internet. These cookies do not have access to anything you type into our calculators, because those values stay in your browser and are never sent to us or to any advertising provider.

You can opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of third-party vendors' use of cookies for personalised advertising at aboutads.info or, in Europe, at youronlinechoices.com. Opting out means you will still see ads, but they will be less relevant to you.

More detail on how Google uses data from this site is available in Google's privacy and terms for partner sites.

Managing Cookies

You can manage or block cookies through your browser settings. Blocking cookies may affect some website features, but basic calculator pages are intended to remain usable where possible.

Consent

Where required, we may display a cookie notice or consent banner before using certain non-essential cookies. Your continued use of the website may also be treated as acceptance of cookies where permitted by applicable rules.

Changes to This Cookie Policy

We may update this Cookie Policy when we add or remove analytics, advertising, embedded tools, affiliate features, or other technologies. The latest version will be posted on this page.
