Last updated: 2026. Short version: the converter itself collects nothing; our ad provider collects the usual things ad providers collect.
Nothing. Every conversion runs in your browser with JavaScript — the number you type is never sent to our server, because there's nothing for it to be sent to. We don't run our own analytics and we don't require an account.
This site is supported by Google AdSense. Google and its advertising partners use cookies and similar technologies (including the DoubleClick cookie) to serve ads based on your prior visits to this and other websites. This is how most ad-supported free sites stay free.
You can see and adjust the ad personalization Google shows you at adssettings.google.com, and read Google's own explanation of how it uses data from sites that use its services at policies.google.com/technologies/partner-sites. If you're in the EU or UK, Google requires publishers to obtain consent for personalized ads where legally required — you'll see a consent prompt if this applies to you.
You can also opt out of personalized advertising generally through the Digital Advertising Alliance or by disabling cookies in your browser, though that may affect how ads (and some site features) display.
Some pages link to external sites (Google's own policy pages, for instance). We don't control those sites and aren't responsible for their content or privacy practices.
This site isn't directed at children under 13 and we don't knowingly collect information from them. Ad personalization for users known to be under 13 is disabled at the Google account level, not by us — see Google's policies linked above.
If this policy changes in a way that matters, we'll update the date at the top of this page.
