Questions
What happens if I cancel?+
After Pro expires, you move to Free (5 analyses + 30 chats limit). The desktop app and manufacturing rules keep working, and past analyses stay in your history. Only the Pro features pause until you resubscribe: unlimited analyses and multi-process auto-comparison.
Can I get a refund?+
Yes — 7 days, no questions. Lemon Squeezy processes it directly.
Is my CAD safe?+
Your STP/STEP files never leave your computer, on Pro or Free. Your reports and analysis history are saved on your computer. Pro and Free differ only in usage quota, and data handling is the same.
Which manufacturing processes do you support?+
Today: injection molding, extrusion, blow molding, thermoforming, compression molding, and plastic 3D printing on the plastics side, plus CNC machining, sheet metal, die casting, and metal 3D printing on the metals side. New ones are added once their rules hold up on real files.
Do I need Fusion 360 or SolidWorks?+
No. You only need an STP/STEP file. The desktop app runs standalone — no heavy CAD install required. Available on macOS and Windows (Microsoft Store).
What's the chat for?+
Every report has a chat panel. Click on a flagged issue to attach it as context, then ask about it in plain language, in the report's language. The answer comes from that file's findings, material, and process, not a general chatbot that doesn't know your part. Free includes 30 chat questions; Pro is unlimited.
