The calculators run entirely in your browser. The values you enter stay on your device, except that they are placed in the page address (URL) so you can share a result; anyone you send a link to can see those values.
We do not use accounts, and this site sets no cookies of its own. The site is served through Amazon CloudFront with request logging turned off: the host keeps only aggregate traffic metrics (request counts and error rates), not a log of individual visits or IP addresses. The site keeps no server logs of its own.
This site currently shows no third-party ads and loads no third-party scripts. If that changes, this page will be updated before it does.
Product analytics
This build of the site collects no usage analytics.
Sale and sharing of personal information
We do not sell or share personal information as those terms are defined in US state privacy laws, and we honor Global Privacy Control signals as an opt-out: with Global Privacy Control on, the optional scripts stay off and our own usage analytics send nothing.
