Frequently asked questions about MindSpark
Where are my mind maps stored?
Maps are saved as private JSON files in a repository called 'mindspark-maps' on your GitHub account. You can git clone the repository anytime.

MindSpark runs entirely in your browser. The GitHub token is stored only in localStorage on your device and sent only to api.github.com—never to any third party.
How do I revoke MindSpark's access?
Visit github.com/settings/tokens and revoke the personal access token you created for MindSpark.
What keyboard shortcuts are available?
Tab creates child, Enter creates sibling, arrow keys navigate, F2 or double-click edits, L links, Del removes, and ? shows all shortcuts.
