What you will find here
Each tool does a single job and works on a phone as well as on a laptop. There is nothing to install and no account to create.
The tools run in your browser. Results you save stay on your device: they are not sent to us. Our privacy page explains this in detail.
Who runs it
Cert Practice Test is published by Click Clack Labs LLC, based in the United States. You can reach us through the contact page.
How the site pays for itself
The site does not show advertising at the moment. If that changes, this page and the privacy page will say so.
How pages are checked
Pages are checked as we go: lists are read against their sources. Read the editorial standards for the details and for how to report a mistake.
