Gmail Email Extractor for Windows is a specialized desktop utility designed to harvest and organize email addresses from Google Workspace and Gmail accounts without relying on third-party cloud servers. Unlike native tools such as Google Contacts or Google Takeout—which only surface saved address books or raw MBOX archives—this application connects directly to live mailboxes to identify active correspondents buried inside message threads, sent mail, and custom labels. Security & Architecture: The software interfaces with Gmail using official Google OAuth 2.0 authentication. Users authorize access directly through Google's consent screen; the software never collects, intercepts, or stores user passwords. All email fetching, parsing, and address deduplication take place strictly on the user's local Windows machine. No message data, contact details, or credentials are ever uploaded to external servers.
