Privacy

This site does not run advertising or analytics, does not offer account registration, and does not operate a contact form. Calculator entries are processed in your browser; do not enter personal or sensitive information.

The hosting provider receives technical request information needed to deliver and protect the site. External source links take you to other websites with their own privacy practices.

If you follow an affiliate link, our affiliate partner and the destination retailer may set or read identifiers on their own domains in order to attribute the referral and any resulting purchase. That processing takes place on their systems, not on this site.

The operator and a public contact email are published on the contact page.
