What cookies are
Cookies are small text files stored by your browser. Similar technologies can also store identifiers or measure how a site is used.
Cookies used on this site
We use Google Analytics to understand aggregate traffic and page use. Analytics may set cookies that distinguish browsers and sessions. Our static site does not require an account or shopping-cart cookie.
Third-party pages
When you follow a provider, social or other external link, that third party may set its own cookies. This policy does not cover third-party websites.
Your controls
You can block or delete cookies through your browser settings. Blocking analytics cookies should not prevent the article, tables or calculator from working. Browser privacy tools and Google controls may provide additional choices.
Updates and contact
We may update this policy when analytics or hosting changes. Questions can be sent to [email protected].
