The launch calculators work in your browser. This page explains that behavior separately from the requests needed to load the website.
Calculator inputs
The calculator performs conversions locally in your browser. Its conversion code does not send the amounts you enter or the ingredients you select to a calculation service. Copying a result uses your device’s clipboard when you request it; printing opens your browser’s print workflow.
The launch tools do not require an account. A copied or printed result is then handled by your browser, operating system, or chosen destination.
Correction notes
The contact and corrections page provides a template to copy locally. It is not a submission form and does not deliver a message to the site. Do not put private account information into a correction note.
Website requests and hosting
Loading a page sends ordinary connection information to the services that deliver it. Hosting, caching, security, and server logs may process information such as an IP address, the requested address, browser information, and request time.
This page does not promise that the hosting infrastructure keeps no logs or uses no cookies. Those services have their own operational practices. The calculator’s local processing is not a guarantee that every website request is anonymous.
Website analytics
We use Google Tag Manager to load Google Analytics and measure how people use the site. This may include page visits, site interactions, and browser or device information. Google Analytics may use cookies or similar identifiers for measurement. Read how Google uses information from sites that use its services. You can manage cookies in your browser.
Advertising and cookies
This site loads a Google AdSense script for site verification and to support advertising if enabled. Loading it sends a request to Google. Google and its partners may use cookies, web beacons, IP addresses and other identifiers to deliver, personalize and measure ads. Information may be collected, used or shared in that process. See how Google uses information from sites that use its services.
The calculator does not require advertising cookies to perform a conversion. You can manage cookies in your browser and adjust personalization through Google My Ad Center.
Links to other websites
Source links take you to independently operated websites. Following a link makes a request to that destination, whose privacy practices apply there. This site’s policy does not describe those external services.
Your browser controls
You can use your browser’s controls to inspect or remove site data and manage permissions. The current contact page states the available communication options; corrections are handled on the report page.
This notice describes the launch implementation. Changes to the site’s integrations or services require a corresponding review of this notice.
Submitted corrections
Report an error sends the information you enter to this site for review. No account, name or email is requested. The report is available only to site administrators and is not published automatically. The form uses a temporary keyed hash of the connection address to limit repeated submissions. Do not include personal information in the report.
