# Data and model licences

Mova's **own** code, data and models are under the **Elamur Cosmic License** ([Elamur Cosmic License](https://md.mova.elamur.ai/free/en/docs/LICENSE/)). It allows everything, except Big Brother.

**Third-party** data and anything derived from it keep the terms their sources require (section 7 of the license). A build gate (`en::license::commercial_gate`) refuses training sources whose license is unknown or restricts the purpose of use.

- **Never shipped:** data under non-commercial (NC), no-derivatives (ND) or research-only terms. Benchmarks under such terms are only *measured against*; their files are not in this repository.
- **CC BY-SA, as little as possible:** we quote it, test and measure on it, and learn from it. We do not ship it or modified copies of it. Files whose header declares CC BY-SA stay out of the free release (`tools/freesync` holds them). A model trained on CC BY-SA treebanks stays under CC BY-SA.
