About draw.io
draw.io is a diagramming application for creating diagrams. It is available as a web app and as a browser extension. The homepage describes it as free. Diagram files from 2005 open in the current app, and anyone can open and edit draw.io files on any platform. Several people can work on the same diagram at once with shared cursors. Users can start without an account.
The homepage says users can store their data wherever they choose and that the company cannot access it. When files are kept in connected services such as Google Drive or Microsoft OneDrive, those services' own handling of data applies. Teams should check the storage option they use before relying on the privacy statement.
