This page explains what data Numerus collects and what it does not. The short version: it collects nothing. Last updated .
What this site collects directly
Nothing. Numerus is a static website. The conversion happens entirely in your browser; no number you type is ever sent to a server. There are no accounts, no cookies set by Numerus, and no analytics scripts.
Advertising and tracking
There are none. Numerus carries no advertising, no third-party ad scripts, and no tracking or advertising cookies. Nothing on these pages profiles you or follows you to other websites.
Third-party requests
The only external resource these pages load is the web fonts used for typesetting, served by Google Fonts. Requesting a font necessarily reveals your IP address and browser user agent to that service; it sets no cookies here and nothing identifies you personally.
Hosting logs
The hosting provider (Cloudflare Pages) maintains short-term server logs that include your IP address, browser user agent, the page you requested, and a timestamp. These are standard request logs used to operate the service and detect abuse; they are not joined with any other data and are not used to identify visitors.
Children
Numerus is a general-purpose utility and is not directed at children under 13. It does not knowingly collect any personal information from anyone, of any age.
