DigInterface Tools stores your DigInterface API key locally in your browser to authenticate requests. When you use a tool (DNS lookup, SSL check, blacklist check, WHOIS, SPF expansion, propagation check, or email header analysis), the domain, IP, or text you submit is sent to the DigInterface API (https://www.diginterface.com) to generate results, along with your API key. No browsing history, personal data, or analytics are collected or transmitted by the extension itself.
