Calculator inputs and saved drafts

Calculator inputs are processed in your browser. A draft is saved automatically in this browser so you can return to unfinished work.

Reset all inputs clears that form’s saved draft, result and shared-estimate fragment. You can also clear saved site information through your browser settings. The site has no account system or database for storing your calculator inputs.

Shared estimate links

When you copy an estimate link, the URL includes the figures needed to restore that estimate. Anyone you give the link to can use those figures to open the calculation.

Copying a link is separate from saving a draft in your browser.

Country and appearance preferences

The site saves your chosen country and appearance in your browser. You can change them using the header controls.

With your permission, browser location helps choose a supported country. Latitude and longitude are checked against bundled country boundaries on your device. The site does not store coordinates or send them to a geocoding service; only the country code is saved.

A saved choice or a country-specific page takes priority. If location is denied, unavailable or outside the supported countries, the site uses its configured fallback or your saved choice.

Analytics and cookies

Analytics are optional and nothing is loaded until you choose Allow on the analytics banner. If you allow them, the site uses Google Analytics cookies to count visits and see which pages and calculators are used.

Google Analytics never receives the values you enter, your share links or the names of files you download. You can change your mind at any time with Cookie choices at the bottom of every page.
