The site is a static set of pages. Concrete calculations run in your browser; there are no user accounts, calculation backend, or advertising conversion tags. The production site may display Google AdSense advertising. Where a Google consent message applies and is available, Google Privacy & messaging provides the consent choices. Google and its advertising partners may use cookies or similar browser technologies and process information for advertising.
Google Analytics 4 is configured for the production site. The tag sends an automatic page view when a page loads; the page URL and referrer are passed without query parameters or fragments. The site code does not send calculator entries, calculation results, copied content, or custom calculator events. Other automatic interaction events depend on the web data stream’s Enhanced measurement settings.
Hosting and scripts
When you visit the production site, Cloudflare handles page and asset requests and standard connection data under its terms. The AdSense script and configured GA4 tag load only on the exact HTTPS production origin. Local, preview, workers.dev, and www hosts do not request Google scripts.
Calculator entries
Calculator arithmetic runs in your browser and does not use a calculation API. When a visitor follows a link from a quantity estimate to a related cost tool, a limited set of values may be included in this site’s URL. URLs can remain in browser history and may be included in ordinary page requests received by the hosting provider. The GA4 page-view URL and referrer omit query parameters and fragments. Do not enter private or sensitive information into a tool; its purpose is concrete quantity and planning estimates.
Advertising and consent choices
Before an advertising or analytics tag loads, the page sets Google Consent Mode defaults to denied for ad storage, ad user data, ad personalization, and analytics storage. The site does not infer consent from location or set a region-based granted default. Google Privacy & messaging may update consent signals based on its message and the visitor’s applicable choice. Denying consent does not stop every request: Google tags may send limited signals without consent cookies. These signals are not complete analytics and are not a record of every visitor. The site does not keep a separate copy of a consent choice.
When the footer’s Cookie settings control is available, it opens Google’s consent-revocation message for visitors whose consent API reports that GDPR applies. Google’s own opt-out controls for other regions remain available as provided. For Google’s data practices, see the Google Privacy Policy.
