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.

Sources we use

Images and contributions

Product photographs remain the property of the source they came from. Images from the Open Food Facts family are made available under Creative Commons Attribution-ShareAlike. Ingredient and nutrition text is edited by contributors to those projects; corrections are best made at the source, where they also improve every other reuser.

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.
