Calculator data

Calculator values are processed in your browser. We do not provide a backend endpoint or database for storing those values.

When you choose to share a calculation, the values are encoded in the URL on your device. Anyone receiving that URL can read them. Do not add information you consider sensitive.

Optional analytics

If NEXT_PUBLIC_GA_ID is configured, Google Analytics 4 is available only after you affirmatively accept analytics. Reject and accept are presented equally, and your choice is stored locally in your browser.

After consent, the site can send sanitised page views plus these named events: calculator_completed, calculation_out_of_scope, result_shared, result_printed, guide_opened and marketplace_selected. Page locations contain only the site origin and pathname. The site does not send order values, calculator amounts, contact information, query parameters or URL fragments. Automatic page views are disabled to prevent duplicate or unsanitised collection.

Changing or clearing your choice

Use “Change analytics preferences” in the footer at any time. Clearing this site’s local storage also removes the saved choice.

Hosting and third parties

A production host can process normal technical request information such as IP address, user agent and requested path for security and delivery. Review your chosen host’s terms before deployment. External official-source links are governed by those sites’ policies.
