Is Webmiru safe?

Low risk

Webmiru sends the domain, detected technologies and found emails of each viewed site to a publisher-run Google Apps Script.

When the popup opens, the extension looks up the active tab's domain on hunter.io, which receives the hostname, to find email addresses. It then posts the domain, detected technologies, harvested emails and page language to a Google Apps Script endpoint run by the publisher, whether or not the email lookup succeeds. A hunter.io API key is embedded in the extension's code.
