Privacy Policy

This site does not require account registration and does not ask for passwords, payment cards, IDs, marketplace credentials, or API keys.

Calculator inputs are processed in the browser for planning estimates. Optional Google Analytics, Cloudflare Web Analytics, or Google AdSense load only when public deployment variables are configured.

Google advertising services and other configured Google services may collect, share, and use data to deliver, personalize, and measure ads, measure traffic, and prevent fraud. As a result of ad serving, Google and its partners may place or read cookies in your browser or collect information using web beacons, IP addresses, and other identifiers. See How Google uses data on partner sites or apps.

If advertising is enabled, Google and third-party ad vendors may use advertising cookies to serve ads based on prior visits to this site or other sites. Users may opt out of personalized advertising through Google Ads Settings and may manage some third-party ad vendor cookies through aboutads.info.

When you change the site language, this site stores the first-party gpk_locale cookie for up to one year and the gpk.preferredLocale local-storage value on your device to remember that choice. You can remove them in your browser settings; changing the language again updates them.

Contact messages should not include sensitive personal, financial, tax, or platform account data.
