Data sources and licenses

This page covers everything the app shows besides your own entries — where food and product data, formulas and software come from — and what you can reuse.

Foods and dishes

Per-100 g values in our food guide are our own compilation: averages from USDA FoodData Central and, for Russian dishes, the food composition tables edited by I. M. Skurikhin; dishes are calculated from a typical recipe; everything is rounded. The figures themselves are facts, but we do not relicense a compilation taken from someone else’s book — so the open ratings table has no composition columns.

The ratings table (Nutri-Score points and grade, traffic light, servings, the “is it healthy?” verdict) is our own work and is open under CC BY 4.0. How it is calculated, with the primary sources for every formula and threshold, is on the methodology page.

Barcoded products: Open Food Facts

Nutrition data for barcoded products and “Shop products” in search come from the open Open Food Facts database: © Open Food Facts contributors, the database under the Open Database License (ODbL) 1.0, individual contents under the Database Contents License 1.0 (Open Food Facts terms). The credit is shown under the product card. We don’t show Open Food Facts product photos.

Our barcode database is derived from Open Food Facts, so under ODbL 1.0 we publish how it is made and everything we added:

• Open Food Facts rows are selected from their open dump (world.openfoodfacts.org/data): Russian products (codes 460–469 or Russia among the countries sold) — all of them, including name-only ones; products of other countries — only with plausible nutrition (1–900 kcal, protein, fat and carbohydrate each at most 100 g and together at most 105 g, calories consistent with 4-9-4). We keep the code, the name with the brand and nutrition per 100 g; sodium is converted to salt (× 2.5), kilojoules to kilocalories;
• everything we added — labels photographed and checked by our users (including nutrition added to Open Food Facts products that had none) and USDA FoodData Central rows — is in barcodes.csv: code, name, nutrition per 100 g and the row’s source (label, usda); no record authors; refreshed daily.

Reuse it under ODbL: credit “© Open Food Facts contributors; Calories Not Count” and share databases built on it under ODbL too.

USDA FoodData Central

The U.S. Department of Agriculture’s FoodData Central is in the public domain. It is the source for much of the food composition, the weights of spoons and cups (by the food’s density) and medium piece weights of fruit and vegetables.

Formulas, Nutri-Score and activity

We calculate Nutri-Score ourselves from the published 2023 algorithm; the official Nutri-Score logo is a trademark of Santé publique France and we don’t use it. Minutes of movement use the Compendium of Physical Activities. The full list of primary sources is on the methodology page.

Software

Where the browser has no built-in barcode reader, barcodes are read on your device with ZXing-C++ (Apache 2.0) built as zxing-wasm (MIT); on-device label reading uses Tesseract OCR (Apache 2.0) with tessdata language files (Apache 2.0). License texts sit next to the files: /zxing/NOTICE.txt, /tesseract/NOTICE.txt.
