Privacy policy

What we collect

We use Cloudflare Web Analytics to collect anonymous, aggregate site usage data. This includes page URL, referring page, country (not city), device type, and browser type. No cookies are set. No IP addresses are stored. No cross-site identifiers are used. Cloudflare Web Analytics is a privacy-preserving analytics service specifically designed to avoid tracking individual users.

We do not collect, store, or process any personally identifiable information via the calculator, the estimator, or any other tool on this site. Calculator inputs stay on your device — they are never transmitted to our servers or any third party.

Cookies

This site does not set cookies. Because we do not set cookies, there is no cookie consent banner and no cookie preferences to configure.

Third parties

The only third-party service loaded on our pages is Cloudflare Web Analytics (`static.cloudflareinsights.com`). We do not use Google Analytics, Facebook Pixel, or any advertising or retargeting network. We do not embed third-party fonts, YouTube videos, or social widgets.

If we add third-party services in the future — for example, an affiliate link tracker or an email newsletter platform — this policy will be updated before those services go live, and we will disclose them explicitly on the disclosure page.

Your rights

Because we do not collect personally identifiable information, we cannot associate any data with a specific individual. There is no user account to delete, no email list to unsubscribe from, and no personal data to request export of.

If you have a specific privacy question, contact us via the address on the disclosure page.

Changes to this policy

If we materially change how we collect or use data, we will update this page and the "Last updated" date at the top. Minor clarifications will not trigger a version bump.
