Trademark

Warranty Disclaimer
-------------------

AION Clinical is **NOT a certified medical device** under the EU
Medical Device Regulation (MDR 2017/745). It is provided as a research
and decision-support tool. Use in clinical decision-making about
specific patients requires either:

  - MDR certification by the operator, or
  - Use under explicit research-only conditions with appropriate
    clinical supervision.

The dual licence does not change this. Even under a commercial licence,
the operator remains responsible for regulatory compliance in their
jurisdiction.

See LICENSE / LICENSES/EUPL-1.2.txt Article 7 (Disclaimer of Warranty)
and Article 8 (Disclaimer of Liability) for the full disclaimer.
