Who runs this site

Zento Tools Hub is run by a single independent operator. There is no company entity behind it.

Data you enter into tools

Most tools on this site (CSS calculators, generators, and converters) run entirely in your browser using JavaScript. What you type is never sent to our server for those tools.

A small number of tools need to make a request on your behalf — currently, the HTTP Header Checker. For that tool, the URL you enter is used only to make the request and is not logged or stored afterward.

Contact form

If you use the contact form, your name, email address, and message are sent to the site operator by email so we can reply. This information isn't used for any other purpose or shared with third parties.

Cookies and advertising

This site may show ads, including through Google AdSense. Advertising partners may use cookies or similar technology to show relevant ads and measure performance; see our Cookie Policy for details. We don't currently run our own analytics tracking, but if that changes, this page will be updated.

What we don't do

We don't sell personal data, and we don't require an account or collect more information than a page genuinely needs to function.
