Data sources and licences.
Vectrome’s food search and food details draw on two open food databases. Vectrome keeps its own copy of each and builds its catalogue from a dated export. Foods you log keep the values they had when you logged them.
Open Food Facts
Packaged products in food search and their details, foods logged from them, and the energy cross-check behind Vectrome’s category estimates.
