All calculations run inside your browser. We do not store, transmit, or process any personal data you enter into our calculators. We do not require accounts. We do not sell data to anyone.
Calculator inputs: None. Values you enter (height, weight, income, date of birth, etc.) are processed entirely in your browser using JavaScript and are never sent to our servers.
Server logs: Like all websites, our servers automatically receive standard HTTP request logs: IP address (anonymised after 24 hours), browser type, page requested, and timestamp. These are used only for security and performance analysis and are never associated with your calculator inputs.
Analytics: We use Google Analytics to understand aggregate traffic (page views, country, device type). This data is anonymised and cannot identify you personally. You can opt out using the Google Analytics Opt-out Browser Add-on.
Advertising: We use Google AdSense to display ads. Google may use cookies to show relevant ads based on your browsing history. See Google's Privacy Policy and Ad Settings.
We do not set cookies for calculator functionality. Third-party services (Google Analytics, Google AdSense) may set their own cookies. You can manage cookies through your browser settings.
Since we do not collect personal data, there is nothing to access, delete or export. If you have questions about data held by Google as a result of visiting our site, please refer to Google's privacy tools.
