How H2Prism handles analytics, browser-based tools, and the disabled newsletter interest surface.

Calculator inputs, searches, filters, drawers, and map exploration work in your browser. H2Prism does not require an account for those free surfaces.

Analytics

Visitors in the European Union, Iceland, Liechtenstein, Norway, the United Kingdom, and Switzerland see an analytics choice, and Google Analytics loads only after they choose Allow analytics. If we cannot determine your country, we show the same choice.

For visitors elsewhere, Google Analytics loads on the first page without a prompt. Google Signals, ad storage, and ad personalization are off. Custom events send only a fixed event name and a small set of bounded values, never calculator inputs, search terms, email addresses, or full URLs.

To choose whether to show the prompt, our server reads only the country code that our hosting provider attaches to each request. H2Prism does not store your IP address.

Vercel Web Analytics counts page views in aggregate without cookies. It runs whether or not you allow Google Analytics.

You can turn off Google Analytics on this device at any time.

Inquiries

When the inquiry form is enabled, H2Prism stores your email address, message and consent record privately and sends the inquiry through Gmail to the operator’s designated inbox for review and response. The inbox is separate from the public contact address. Submitting an inquiry does not enable automated replies, classification, subscriptions or scheduled processing. Email acceptance does not confirm inbox arrival or a reply.

Newsletter production and private review are underway. Public email or Beehiiv delivery and signup are not enabled, so H2Prism does not collect email addresses on this page.

Do not enter personal, confidential, or regulated information into calculators or data filters.
