Cookie and browser-storage policy

Essential local preferences

BuildPlanCalc stores your light or dark theme choice and analytics preference in your browser's local storage. These values keep the interface consistent and remember whether analytics should run on that device. They do not contain calculator measurements or results.

Shareable estimate values appear in the page URL only when you choose Copy link. They are not a cookie, but anyone receiving that URL can read the included values.

Firebase Analytics

On the production website, Google Analytics for Firebase may use cookies, local storage, or similar identifiers to measure visits and limited interactions. BuildPlanCalc excludes localhost and test traffic and does not deliberately send calculator inputs, results, or typed search phrases as analytics parameters.

Google advertising cookies

BuildPlanCalc does not currently display Google AdSense advertisements. If advertising is enabled, third-party vendors including Google may use cookies to serve ads based on a visitor's prior visits to this website or other websites. Google's advertising cookies allow Google and its partners to serve and measure ads, including personalized ads where the visitor has provided any required consent.

Visitors can manage personalized advertising in Google Ads Settings. Additional advertising vendors will be disclosed here or through the site's consent interface before their technology is enabled.

Consent and changing your choice

When advertising begins, BuildPlanCalc will use an appropriate consent mechanism for regions where consent is required. Visitors in the EEA, United Kingdom, and Switzerland will be shown a Google-certified consent management platform before eligible personalized advertising is served.

Your browser can also block or delete cookies and site storage. Doing so may reset theme, analytics, and future advertising preferences. See the Privacy Policy for the broader data-use notice.
