+# Commercial License — RIFT
+
+RIFT is **dual-licensed**.
+
+- For **noncommercial** use, the [PolyForm Noncommercial License 1.0.0](LICENSE) applies
+  automatically and at no cost.
+- For **commercial** use, you need a separate **commercial license** from the copyright
+  holder. This document explains what that means and how to get one.
+
+## What counts as commercial use
+
+A *commercial use* is any use whose primary purpose is commercial advantage or monetary
+compensation. This includes, without limitation:
+
+- Using RIFT (or any derivative or model trained with it) in a product, service, or
+  internal tool that is part of a revenue-generating activity.
+- Offering RIFT-based inference, training, or hosting to third parties, paid or unpaid,
+  as part of a commercial offering.
+- Use by a for-profit company in the course of its business, including internal R&D, even
+  if the result is not directly sold.
+
+If you are unsure whether your use is commercial, assume it is and ask. We are friendly.
+
+## What is always free (no commercial license needed)
+
+- Academic and nonprofit **research**, including by company research labs publishing openly.
+- **Study, teaching, coursework**, personal and hobby projects.
+- **Evaluation and benchmarking** of RIFT, including reproducing the results in this
+  repository.
+- **Citing** RIFT in any publication (citation never requires a license).
+
+(See the PolyForm Noncommercial License for the precise scope — charitable, educational,
+public-research, and government institutions are explicitly covered regardless of funding.)
+
+## What a commercial license grants
+
+A commercial license is negotiated per engagement and can cover, depending on your needs:
+
+- The right to use RIFT and derivatives for commercial purposes.
+- The right to ship RIFT (or a fine-tuned/derived model or kernel) inside a product.
+- Optional support, integration help, and early access to unreleased improvements.
+
+Terms (scope, field of use, fees, duration) are set in a written agreement. Startups,
+indie developers, and small teams: tell us your situation — pricing is flexible.
+
+## How to obtain one
+
+Email **contact@harmoniclabs.cc** with:
+
+1. Who you are (individual / company) and a one-line description of the intended use.
+2. Scope: internal use, embedding in a product, hosting/SaaS, or model distribution.
+3. Rough scale (team size, deployment scale) so we can size a fair license.
+
+We aim to reply quickly. Building something real on RIFT is exactly what we want — the
+commercial license just keeps the lights on and the research going.
