The Docs to Markdown add-on does not collect or distribute any information about you or about the documents being converted.
Docs to Markdown will ask for permission to access the current Doc (to convert it). Docs to Markdown reads the Doc content and structure; it does not change any content.
Docs to Markdown will also ask for permission to display a sidebar. It uses the sidebar to display action buttons and option checkboxes as well as the converted text (Markdown or HTML).
It requires no other permissions.
See the Docs to Markdown wiki for Docs to Markdown documentation and installation information.
