Analytics

We use Google Analytics 4, a service provided by Google, to understand how the site is used: which pages are visited, how visitors arrive (for example from a search engine), and the general type of device and browser used.

Google Analytics uses cookies (such as _ga) to tell visits apart. It reports approximate location, such as country or city, based on your IP address. Google Analytics 4 does not log or store IP addresses.

The measurements, densities and prices you enter into the calculators are not sent to Google Analytics.

You can block or delete these cookies in your browser settings, or install Google's Google Analytics opt-out browser add-on. Google explains how it uses this information in How Google uses information from sites that use its services.

Hosting

Like most websites, our hosting provider may record standard technical information such as IP addresses and pages requested, for security and reliability.
