Product data comes from Open Food Facts, available under the Open Database License (ODbL) 1.0; individual contents under the Database Contents License. Every verdict links its OFF product page. Product photos are served from the Open Food Facts image database, © their photographers, under CC BY-SA 3.0.
Our OFF-derived slice is a derivative database. Per ODbL §4.6 we publish both the machine-readable slice (JSONL download) and the alteration algorithm: the OFF export is filtered to food records with 8- or 13-digit codes; kept fields are code, name, brands, ingredients text + language, additives/analysis/categories tags, a nutriment subset (energy, carbohydrates, sugars, fat, saturated fat, proteins, salt per 100 g), and NOVA group; empty strings normalize to null; a PUFA seed-oil lexicon over the ingredient text adds derived tags. Verdicts are Produced Works (§4.5b). User contributions and judge rule-sets live in separate databases joined by barcode at read time (§4.5a collective database).
No accounts, no cookies, no analytics. Judge picks and scan history live in your browser's storage and never reach a server database; verdict requests carry your judge selection only as request parameters, answered and forgotten.
