FabFlow is an Autodesk Inventor add-in developed by RMAC Design (“we”, “us”, “our”). This document covers the terms of use and privacy practices for FabFlow, including the software, website, and related services.
By installing or using FabFlow, you agree to these terms. If you don’t agree, don’t install or use the software.
A personal, non-exclusive, non-transferable license to use FabFlow on the machine(s) permitted by your subscription plan.
Your license is tied to a specific machine using a hardware fingerprint. You can deactivate a machine and reactivate on another through the add-in settings.
FabFlow offers a 14-day free trial with full functionality. No payment is required to start the trial.
After the trial, a paid subscription is required to continue using FabFlow. Subscriptions are billed and managed through Lemon Squeezy, our payment processor.
You can cancel your subscription at any time. Cancellation takes effect at the end of your current billing period — you keep access until then.
Because FabFlow offers a free 14-day trial with full access to all features, we do not offer refunds on subscription payments. You have the opportunity to fully evaluate the software before committing to a purchase.
FabFlow is provided “as is” without warranty of any kind. We don’t guarantee the software will be error-free, uninterrupted, or compatible with every Inventor configuration.
To the maximum extent permitted by law, RMAC Design is not liable for any indirect, incidental, or consequential damages arising from your use of FabFlow. This includes but is not limited to lost data, lost profits, or damage to your Inventor models or assemblies.
Our total liability is limited to the amount you paid for FabFlow in the 12 months preceding the claim.
We may update FabFlow at any time. We’ll make reasonable efforts to notify subscribers of significant changes via email.
We collect the minimum data necessary to operate the software and process payments.
