The extension does not make network requests and does not require external accounts.
The popup and the notice shown when Enter is stopped include a "Report a problem" link. Choosing it opens a page on kanary.to in a new tab. The link carries the extension version, the current site's host name (only when it is a site Enter Guard supports; any other site is reported as "other"), and your Enter Guard settings. To fill in the host name, the popup uses the activeTab permission to read the current tab's address while the popup is open. Nothing is sent to Kanary unless you submit the form on that page, and no page content or typed text is ever included.
