If you only work solo or do not have a reliable internet connection, you can use the separate Goalscape Desktop Offline standalone software. It is also ideal for running bulletproof Goalscape presentations offline anywhere. You can download it here:
Goalscape Desktop app for Windows / Goalscape Desktop app for macOS
In Online you can download your projects as .gsp files that you can open in the Desktop Offline app, and upload .gsp files to create Online projects. Please note though that there is no automatic sync between the two products.
