The public data and the tools Griddle relies on, what each is for, and its licence.
Nutrition and ingredients
To recognise a recipe's ingredients and work out its nutrition values.
Nutritional composition
Licence Ouverte / Etalab 2.0
What it is forIt gives each food's energy, protein, carbohydrates, fat and salt. Griddle adds them up to show a recipe's nutrition values per serving, and uses it to recognise ingredients by name.
Anses, Ciqual French food composition table, 2025 edition, updated on 3 November 2025. Data adapted by Griddle.
What it is forThe Ciqual table does not know some foods common elsewhere (wasabi, edamame, kimchi…). This table completes it, so that their nutrition values count too.
U.S. Department of Agriculture, FoodData Central. A selection of foods, named in French by Griddle.
What it is forIt adds foods no table holds, and their names in five languages, to recognise an ingredient even in a recipe written in another language.
Wikidata, contributors of the Wikimedia Foundation.
What it is forIt says in which months a fruit or vegetable is in season. The Menu's ideas point it out (“In season: pumpkin”), and your journal counts the share of your dishes cooked in season.
ADEME, seasonal fruit and vegetable calendar, 2025 edition. Data adapted by Griddle.
These three sources estimate what a recipe and your shopping list cost (“≈ €12”). For each food, Griddle takes the first one with a recent price, in the order below. With no recent price, it shows no price rather than an old one.
Fresh produce prices
FranceAgriMer open licence
What it is forThe prices of fruit, vegetables and fresh produce noted each week in supermarkets. It is the freshest source, the one that follows the season: Griddle reads it first.
FranceAgriMer, Market News Network (RNM), quotes published weekly. Data adapted by Griddle.
What it is forA product's average price in France, each month, when the market network does not quote it. The indices also bring an older price up to date.
INSEE, average retail prices and consumer price indices, published monthly. Data adapted by Griddle.
What it is forPrices noted in shops by contributors, for the grocery products the two public sources do not cover. Griddle keeps only a median per kind of product.
Open Prices — Open Food Facts contributors. Contains information from Open Prices, which is made available under the ODbL.
What it is forThe small round pictures beside each ingredient, to spot a food at a glance. Every generated picture carries a machine-readable mark that says it was generated.
Images generated by artificial intelligence (ChatGPT) for Griddle, each checked by eye. A few ingredients are still illustrated by public-domain or CC0 photographs (Wikimedia Commons, USDA).
Face detection
Apache License 2.0
What it is forWhen you share a photo outside your family, on the Feed or from your journal, Griddle looks for a face on it, to remind you to ask the person. It only sees that there is a face: it recognises nobody. It happens on your device; the photo is sent nowhere for it, nothing is kept, and no request goes to Google.
Google, MediaPipe Face Detector and its BlazeFace model, which run on your device.
