All your designs and projects are stored locally on your iPad.
If you have a Business license, then you can export your projects to third-party cloud apps in all supported formats and export 2D drawings in DXF, DWG, or PDF format.
If you have a Standard license, then you can export your projects to SHAPR, STEP, IGES, OBJ, SVG, USDZ, DXF (sketches only), and high-quality STL and 3MF; you can also save your projects as images.
If you're using Shapr3D Basic, which is the free version, then you can only export your projects to low-quality STL and low-resolution 3MF.
