Privacy Policy

Effective date: August 19, 2026

Calculator inputs

The public calculators are designed to perform calculations in your browser. The site does not require you to create an account to use them. Calculator inputs are not intended to be used to identify you, and you should not enter sensitive personal information into calculator fields.

Google Analytics

We use Google Analytics 4 (“Google Analytics”) to understand how visitors find and use the website, such as pages viewed, general engagement and device/browser information. Google Analytics may use cookies and similar technologies, including first-party identifiers used to distinguish users and sessions.

Information generated through Google Analytics is processed by Google under Google’s applicable terms and privacy practices. We use analytics information to improve calculators, site performance, navigation and content.

Advertising and Google AdSense

The site may display advertising through Google AdSense or other advertising partners. Third-party vendors, including Google, may use cookies or similar technologies to serve, measure and personalize advertising where permitted. Google and its partners may use information about visits to this site and other websites to help provide relevant advertising.

Where required, visitors will be given consent or privacy choices through an appropriate consent-management system before advertising technologies that require consent are used.

Cookies and similar technologies

Cookies may be used for analytics, security, preferences, advertising measurement and, where permitted, advertising personalization. The exact cookies present can change as services are added, removed or configured.

Your choices

You can use browser controls to delete or block cookies. Where a consent or privacy-choice message is presented, you can use that interface to manage available choices. Blocking some technologies may affect site measurement or certain features but the core calculator functionality is designed to remain publicly accessible.

Third-party services and links

The site may link to third-party websites or use third-party services. Their privacy practices are governed by their own policies, not this policy.

Data security and retention

We use reasonable technical and organizational practices appropriate for a public informational website. Analytics and advertising data are retained according to the settings and policies of the applicable service providers and our configured account settings.

Children

The site is a general-audience utility website and is not directed to children under 13. We do not knowingly ask children to provide personal information through the calculators.

Changes to this policy

We may update this policy as the website, analytics configuration, advertising partners or legal requirements change. The effective date above will be updated when material changes are published.
