What we collect
Nothing. The calculators and converters on this site run entirely in your browser. Values you type and files you choose stay on your device; they are never uploaded to our servers, because there is no server processing step for these tools.
Cookies and analytics
This site does not set advertising or tracking cookies. If we add privacy-friendly, cookieless analytics in the future, this page will say so first.
Advertising
We may show ads to keep the tools free. Ad providers may use cookies as described in their own privacy policies; we do not control that, and we do not sell or share personal data with them.
