The NameDaemon extension sends the .com name you ask about to namedaemon.com, in the same way as the tools on that site, and gets a result back. It does this only when you press Check or open one of its tools, never in the background (apart from checking whether an audit you started has finished). It reads the address of the current tab only to fill the name into its box when you open it, and does not send that address anywhere. It does not read the content of pages, does not use advertising or analytics services, and does not track your browsing.

The extension stores in your browser the names you save, a short cache of results, whether a section is open, an email address if you type one to watch a name, and, if you connect Pro, your sign-in token. If you ask to watch a name, the email address and the name are handled as described in the privacy policy at https://namedaemon.com/privacy-policy/. Links from the extension to the site carry a fixed tag so we can see how many visits come from it; the tag contains nothing about you. Registrar links shown in the extension can be affiliate links and are labelled as such.
