Disconnecting from Google Drive
Note : If your GSuite admin added draw.io domain-wide, they will have to uninstall it domain-wide rather than following the per-user disconnection process.
Go to your Google Drive home page.
Click the settings option under the cog top-right:
Click "Manage apps" in the dialog that appears and find "draw.io Diagrams".
Click the "Options" pull-down and select "Disconnect from Drive":
Removing Permissions to Access Google Drive
Go to your Google account permissions page.
Find draw.io in the top "Third-party apps with account access" section and click it to expand it.
Click "REMOVE ACCESS" and confirm the dialog:
Your diagrams will remain in your Google Drive, but the draw.io web application will not be able to access your Google Drive.
If you wish to reconnect, select Google Drive for storage from the splash dialog in draw.io online and authorise the application again.
Note that draw.io has been tested extensively for security, including passing Google's security audit for internal usage with Google Drive in 2018. If your IT administrator has security concerns, please direct them at firstname.lastname@example.org and we can discuss them in detail.
