Everfitly ("we", "us", "our") provides free online calculators. This page explains what information is collected when you use this website and how it's used.
The numbers you enter into our calculators (age, weight, height, lab values, etc.) are used only to compute your result on that page. We do not create accounts, and we do not store your calculator inputs or results in any database linked to your identity.
We use Google Analytics to understand overall site traffic — which pages are visited, how long visitors stay, and general location data (such as country or city). This is aggregated, anonymized usage data; it does not identify you personally. Google Analytics uses cookies to collect this information. You can opt out using the Google Analytics Opt-out Browser Add-on.
We may display advertisements through Google AdSense. Google and its partners may use cookies to serve ads based on your prior visits to this or other websites. You can learn more about how Google uses this information and manage your ad preferences at Google's Ads Policy page.
If you use our Contact form, the name, email address, and message you provide are sent to us solely to respond to your inquiry. We don't add you to a mailing list or share this information with third parties.
This site uses cookies for analytics and (where applicable) advertising, as described above. You can disable cookies in your browser settings, though this may affect how some parts of the site function.
This site is not directed at children under 13, and we do not knowingly collect personal information from children.
We may update this policy from time to time. Changes will be posted on this page with an updated "last updated" date.
