Your calculator inputs and searches

Address calculations and role-directory filtering run locally in your browser. Calculator inputs and search terms are not sent to Google Analytics or a site server, stored in a database or saved in browser storage by this site. Your browser may retain or restore form state through its own features.

Optional Google Analytics

Analytics is off until you choose Allow analytics. If you allow it on https://dupery.wiki, the Google Analytics 4 tag can send a page-view event with the page title, page address and a limited referrer. Google also processes connection and device information to operate its service. We do not send calculator inputs, search terms, form values, user IDs or advertising signals. Enhanced measurement is disabled; this site does not add click, search or calculator events.

Ordinary query parameters and URL fragments are removed from the page address sent to Google. An optional, short, non-sensitive ga_check test marker may be retained to verify measurement. Same-site referrers are cleaned the same way; external referrers are reduced to their origin.

Your choice and storage

The choice is remembered in this browser’s local storage as dupery-analytics-choice-v1. If storage is unavailable, your choice applies only to the current page. Allowing analytics lets Google use first-party _ga and _ga_* cookies to distinguish visits. Keeping analytics off does not load the Google tag or send analytics requests. Global Privacy Control keeps analytics off, including when an earlier choice allowed it.

Use Analytics choices in the footer to turn analytics off or reset your choice. Turning it off blocks subsequent analytics and removes the Google Analytics cookies accessible to this site. Previously sent page views cannot be withdrawn here. A reset returns to the undecided, off state. The guides and calculator work with analytics off. Preview, sample and error pages do not initialize analytics.

Advertising

This version does not include advertising scripts or advertising cookies.

Hosting and external links

Requesting a page necessarily shares connection information with Cloudflare, the hosting provider. Existing hosting measurement is separate from the optional Google Analytics choice. Following a source link opens an external site whose privacy rules apply there. Google’s handling of analytics information is described in its privacy policy.
