Privacy Policy

We collect only the information needed to operate the website, respond to messages, and understand aggregate usage patterns. If you use the contact form, the information you submit is processed solely to answer your inquiry.

We do not sell personal data. Third-party services such as hosting, analytics, or form processing may handle limited technical information as part of normal site delivery.

Google Analytics and your choice

Google Analytics 4 measures visits, page views, approximate country, devices, and traffic sources only after you choose “Allow analytics.” The Google tag stays blocked until you allow it. Your choice is stored in this browser for 180 days and can be changed through “Analytics choices” at the bottom of the page. The calculators work when you decline.

Analytics page addresses omit query strings and fragments. We do not intentionally send calculator input values, contact-form messages, names, or email addresses to Analytics. Advertising storage and personalization are disabled for this integration. See Google's privacy policy. Existing analytics cookies can be removed in your browser settings.

If our data practices change in a meaningful way, we will update this policy on the website.
