This doesn’t sound like an issue for those who use Fusion frequently, however you may want to find ways to get local files, just to be safe.

How do you open the files though?
It exports as F3D (probably readable by future versions of Fusion) and STEP (standard but with less fidelity) by default.
Is STEP a CAD format or 3d file format? I thought the latter. Like I don't get constraints or sketches, only 3d models
STEP is at least marginally better than STL, because it can represent stuff like circles, instead of just a mesh.
It’s a CAD format in that the files contain object descriptions instead of meshes (like OBJ). But the format does not support all of fusion 360’s features so it is a lossy export in that respect.
Looks like it only exports them as 3d models and not CAD files
