Cookies and local data.

01Analytics settings

Analytics and ad measurement are enabled by default. There are three choices: “Without analytics” keeps Google Analytics unloaded; “Analytics only” measures visits and inquiries; “Analytics + ad measurement” also allows advertising cookies and sharing events with Google Ads to measure ad performance. Your choice is saved in browser localStorage for up to 180 days. A saved analytics-only preference or opt-out overrides the automatic default. The page address determines the language you see.

When analytics is enabled, Google may set _ga and _ga_* cookies to distinguish visits, with a lifetime of up to 180 days. Advertising cookies such as _gcl_* may also be used to measure clicks and inquiries in “Analytics + ad measurement” mode, which is the default unless a restriction is saved. Inquiry text is not sent to these cookies. Ad personalization and remarketing are not enabled.

When analytics is enabled, the current tab’s sessionStorage keeps allowed campaign parameters, the traffic source and landing page. We use this record for 30 minutes after capture; in ad-measurement mode it may also contain Google click identifiers. It contains no arbitrary URL text or form-field contents. When you submit an inquiry, this data, your measurement choice and whether you used the calculator may be saved in the private inquiry record to evaluate the sources of inquiries and agreed projects. Switching to “Analytics only” removes click identifiers from the current record; disabling analytics clears it. Studio staff can separately exclude their own browser from analytics; this local preference remains until reversed.

You can change or withdraw permission using “Privacy” at the bottom of the page. Switching from “Analytics + ad measurement” to “Analytics only” removes _gcl_* advertising cookies while keeping Analytics enabled. Choosing “Without analytics” removes analytics and advertising cookies and reloads the page to stop the loaded script. Withdrawal does not automatically delete data Google received beforehand. You can also clear site data through your browser settings.

02Drafts and clipboard

Before submission, the details you enter remain in the open browser tab. Your browser may have its own autofill and form restoration features. After submission, a copy of the inquiry is stored on the server; closing the tab or clearing local data does not delete that copy.

The calculator stores selected options and notes in the current tab’s sessionStorage, so changing language or reloading does not lose the estimate. This is local data for the calculator, not tracking. It lasts for the tab session and can also be removed by clearing site data in your browser.
