 ## Licensing and review
 
-This dataset card uses `license: other` because the ISLRTC index pages do not expose a
-machine-readable redistribution license. Website ownership text is not treated as a
-permission grant. INCLUDE is tracked as CC-BY-4.0 based on the local source metadata.
-This public bundle contains metadata and source links only. Complete a separate rights
-review before adding redistributed media or derived motion payloads.
+This dataset card uses `license: other` because it combines source-specific terms.
+The official ISLRTC FAQ permits dictionary use for research, teaching, and technology
+only when the data are not resold or used for profiteering and ISLRTC is properly
+acknowledged. INCLUDE is tracked as CC-BY-4.0 based on its source metadata. This public
+bundle contains metadata and source links only; it does not grant commercial rights or
+permission to redistribute source media or derived landmark payloads.
 
 An official dictionary listing establishes vocabulary provenance; it does not prove
 that this merge or an INCLUDE motion clip received independent ISL expert review.
