Privacy

What ZigProxy collects, what the in-browser tools do with your input, cookies, advertising, and how to contact us about privacy.

Last updated 8 September 2026

The short version#

ZigProxy is a static site. There are no accounts, no logins, no comments and no newsletter. The interactive tools run entirely in your browser and send nothing anywhere.

The tools#

Every tool on this site, the client IP resolver, the no_proxy tester, the proxy_pass simulator, the PROXY protocol decoder, the PAC file tester and the timeout ladder checker, is implemented in JavaScript that runs on your machine.

Specifically:

You can verify this: the tools are plain JavaScript in the page source, and your browser's network tab will show no requests while you use them.

Server logs#

The web server that delivers this site records standard request data, which typically includes the requesting IP address, the time, the URL requested, the referring URL and the user agent string. This is used to operate the site and diagnose faults. It is not used to build profiles of individual visitors and it is not sold.

Cookies#

The site itself sets no cookies for analytics, personalisation or tracking. The search page fetches a static index file so that search runs locally in your browser rather than on a server.

Advertising#

This site may display advertising served by third parties. Advertising networks may set cookies or use similar technologies in your browser, and may collect data about your visit according to their own policies, which are not under our control. Where you are in a jurisdiction that requires consent for this, you will be asked for it before any such technology is used, and you can withdraw consent through the same mechanism.

Advertising has no influence on the editorial content of this site. See editorial standards.

Pages link to specifications, vendor documentation and source repositories. Those sites have their own privacy practices, which we do not control.

Contact#

Privacy questions: privacy@zigproxy.com. See also contact.

This page is updated when the site's data practices change, and the date at the top reflects the last such change.
