Halal Trace
Know what's in it, before you buy it.
Scan a product's barcode or photograph its ingredients label. Halal Trace reads the ingredients, checks every one of them against a curated knowledge base, and tells you where the product stands — and why.
How it works
Three steps, and the first two happen on your phone.
-
Scan or photograph
Point the camera at a barcode, or take a picture of the ingredients label. You can also pick an existing photo from your gallery.
-
Every ingredient is matched
The text is matched against a curated knowledge base of named ingredients and E-numbers, in English, German, Swedish, Spanish and French.
-
You get a verdict, with reasons
A deterministic rule engine turns those matches into halal, haram or doubtful — and shows you which ingredient drove the result.
What it does
Built for the aisle: fast, quiet, and useful when the shop has no signal.
Works offline
The knowledge base lives on your phone, so a scan resolves without a connection. Nothing is uploaded just to get an answer.
You choose how strict
Strict, Balanced or Lenient. It changes only how uncertainty is treated — pork, alcohol and other clearly haram ingredients are flagged on every setting.
More than the verdict
Where the product data has it, you also see declared allergens, cross-contamination traces, and vegan, vegetarian and palm-oil information.
No account, ever
No sign-up, no email, no profile. Your scan history, favourites and settings stay on your device.
History and favourites
Every scan is saved locally so you can find it again, and you're told when a product you saved has since been reassessed.
Your own rulings
Where scholars differ, you can record your own position on a doubtful ingredient and have every future scan respect it.
What Halal Trace isn't
Halal Trace is a tool for reading and assessing ingredients, not a religious authority, and its verdicts are not fatwas. Product formulations and labels change, and the product databases it draws on are community-maintained and uneven — an ingredient or allergen not listed there may still be present in the product.
Always check the packaging yourself, and consult a scholar you trust for a ruling. If a verdict looks wrong, you can report it straight from the result screen.
Where the data comes from
Product information comes from Open Food Facts, an open database made available under the Open Database License (ODbL), and from the U.S. Department of Agriculture's FoodData Central. Ingredient classifications are our own curated knowledge base, with the sources recorded per entry.
