Data sources and attribution
Where the Label Matter catalog comes from, and the licence each source is used under.
Label Matter combines open product databases with licensed commercial data. The PureScore rating itself is ours — it is a produced work calculated from those sources, and none of them endorses it.

PureScore is our own rating
PureScore is a 0–100 rating produced by Label Matter from the sources above. It is not published or endorsed by Open Food Facts, Open Beauty Facts, Open Products Facts, the European Commission, or Nutritionix, and a low or high PureScore is not a statement by any of them about a product.
