Stop sharing

If you have shared a link to your mind map, you can stop sharing that mind map by "deleting" that link. 

To do this, 

1. Open the share dialog
2. Click on the "Link" option
3. Click the "Delete" button next to the link you've shared.

Now the people with a link that was deleted will not have access to your mind map. 

To share the mind map again, click on the "Create" button. This will generate a new link to your mind map.
