Most “markdown to Word” results are web tools that ask you to paste or upload your document to a site you know nothing about. Markd.ly converts from inside the editor, and it tells you where that happens.
On Linux, the app converts on your machine with a converter that ships inside it. On Mac and Windows, Export DOCX sends the document's text over your signed-in connection to our conversion service, which converts it in memory, sends the Word file back and keeps nothing: no stored copy and no log of the text. The request carries the text and the format, not the file's name.
If a document must never leave your computer at all, export it on Linux, use the command-line converter on Windows or Linux (--render in.md --to docx), or export to HTML or PDF, which run on your machine on every desktop.
