Your measurements

Calculations run in your browser. The measurements and optional block price you enter are saved in your browser's local storage so your last calculation is still there when you come back. They are not sent to us or to any third party.

No account, advertising or analytics services are used on this site.

Hosting

Like any website, the hosting provider that serves these pages may process standard technical information such as IP addresses and request logs to deliver and protect the site.

Cookies set by our hosting provider

Our host sets strictly necessary cookies to protect the site from automated abuse and route your visit to the current version of the site. These cookies are not used for advertising or analytics, and Block Estimator does not read them.

If you use our Contact form, we collect your name, the email address you provide for a reply, your selected topic, and your message. We use this information to review and respond to your inquiry.
