That’s fair, and it’s the right thing to weigh with any new tool. Right now it’s a small company and I’ve written most of the engine. What I’ve tried to make sure is that your work never depends on Aircad surviving. Everything exports to DWG, DXF, PDF, and STEP whenever you want, and you can keep native files locally, so the exit path is always open. The engine also runs entirely in your browser, not on our servers. I’d rather earn trust over time than ask for it up front.
