In the beginning the Yuka project relied on Open Food Facts, an open, collaborative database that uses the same model as Wikipedia.
In January 2018, Yuka decided to create its own database in order to implement advanced systems for monitoring and verifying each addition.
Currently our database grows via:
1) Contributions from users.
Users can enter information directly into the application for any products that aren’t recognized by Yuka by adding products' pictures and composition. Many control systems then make it possible to ensure the accuracy of the information.
2) Brands that give us access to their products' data.
We work today with many brands that are willing to provide us with direct access to their product information. Because this information is exactly what is printed on the product labels, there is no conflict of interest involved.
