Every Word document carries your name, company, edit history, revision count, and tracked changes — invisible in the document, visible to anyone who knows where to look.
A .docx file is a ZIP archive containing XML files. The metadata lives in docProps/core.xml and docProps/app.xml — but that's only the start.
Your full name from your Microsoft account or Windows account, plus the name of whoever last saved the file.
Your organisation name from the Microsoft Office license — embedded automatically in every document you create.
How many times the document has been saved, and the total accumulated editing time in minutes.
Resolved and deleted comments often remain in the file. Each carries the commenter's name and timestamp.
Insertions and deletions marked with w:author attributes — revealing who edited what, even after "accepting all changes".
The word/people.xml file stores the identities of everyone who has collaborated on the document.
Accepting tracked changes removes the visible markup — but the w:author attributes on revision elements can persist in the XML. Anyone who opens the file with a developer tool or extracts the XML can still read who made which edit. Ghoststrip anonymises these attributes directly.
Author, last modified by, company, manager, revision number, total editing time, and all date fields in core.xml and app.xml are replaced with empty values.
docProps/custom.xml — which can hold arbitrary key-value pairs added by your organisation's templates — is deleted entirely.
word/comments.xml, word/commentsExtended.xml, and word/people.xml are removed. Comment content and co-authoring identity records are gone.
All w:author attributes on revision elements throughout the document body, headers, and footers are replaced with empty strings. The change markup itself is preserved — only the identity is removed.
Embedded thumbnail images (which can contain rendered page content) and printer settings files (which can reveal network printer names) are deleted.
