Privacy notice

How H2Prism handles 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.

Optional Google Analytics

H2Prism loads Google Analytics only after a visitor chooses Allow analytics. It records aggregate page use and 11 bounded interaction event types.

Custom events do not send calculator inputs, search terms, email addresses, or full URLs; they send only the fixed event name and the bounded property values listed for that event.

Analytics choice

If a visitor chooses No thanks, the analytics script is not loaded. The choice is stored only in that browser and can be reset by clearing site data. Advertising storage, Google Signals, and ad personalization are disabled.

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.
