Is it halal? Scan it and see why.

Know Halal reads every ingredient on the label and tells you Halal, Doubtful or Not halal, with the reason and where it came from. When the label can't settle it, we ask the company.

How it works

From the shelf to a clear answer.

  1. Scan the barcode

    Point the camera at the barcode, or type the number. The ingredient list comes from Open Food Facts, USDA FoodData Central and our own catalogue of more than 500,000 US and Canadian products.Not found? Take one photo of the ingredient panel.

  2. Every ingredient is checked

    Each one is read against rules drafted from published halal certifier guidance: gelatin, enzymes, emulsifiers, flavors, alcohol, and pork in every spelling.

    The Ingredients tab in Know Halal: the label as printed, with marshmallow and gelatin underlined in red and the flavors underlined in amber.
  3. You see the answer and the reason

    Halal, Doubtful or Not halal, with the ingredient that decided it and the source behind it: a halal certifier, the maker's own words, or the label.

    A Know Halal result: Doubtful. Natural flavors needs confirmation. The available information does not settle this yet. Standard profile.
Three answers

Every answer comes with its reason.

Halal

Every ingredient passes on your profile, and the result names the rule or source that settled it. You never have to take it on trust.

  • When a recognized halal certifier lists the product, the result says so
  • Save it to Safe staples, and it is checked again when the label changes
Doubtful

The label leaves a question open. You see the exact question, what the maker or a certifier has already published, and who can answer it.

  • Tap Contact manufacturer and Know Halal asks the maker for you
  • When the answer comes, everyone who asked is told
Not halal

You see the ingredient that decides it, and better options from the same aisle.

  • Pork, in any spelling, is never accepted
  • Meat counts only when it is stated halal
When the label isn't enough

No answer on the label? We go and ask.

  1. The label

    Read first. Most products are settled right here.

  2. The web

    The maker's own site and customer-care pages, and halal certifier listings. You get the link.

  3. The company

    Nothing published? Know Halal writes to the maker with the exact question. You can also email them yourself from the app.

  4. The answer

    Shown with the company's name and the date. Everyone who asked gets a notification.

Is the natural flavor in your cocoa rice cereal plant-derived, or does it contain any animal ingredients or alcohol?

“The natural flavor in this cereal is plant-derived. It contains no animal ingredients and no alcohol.”

Your profile

Scholars differ on some ingredients. You choose.

Standard follows the mainstream certifier consensus. It is right for most people.

Strict wants a certifier named for meat, treats unconfirmed animal sources as not halal, and asks about the alcohol used to carry flavors.

Lenient accepts unspecified enzymes, whey and cheese, and trace alcohol used to carry flavors. Meat still counts only when it is stated halal.

Same label, your rulesVerdict
Natural flavorsDoubtful
Wheya cheesemaking by-productDoubtful
Artificial flavorsHalal
L-cysteine (E920)Doubtful
Chicken, beef or other meatnot stated halalNot halal
Pork, in any spellingNot halal

Meat counts only when it is stated halal: by a recognized certifier, on the pack, or in the maker's answer (Strict wants the certifier named). Nothing clears pork. You can also accept or avoid a single ingredient yourself; it then applies to every product, shown as your own ruling.

Questions

What people ask us.

Is Know Halal a fatwa or a halal certification?

No. It shows you what the label and published sources say, and how the rules read them, with every source named. For a ruling on your own situation, ask a scholar you trust.

Where do the answers come from?

First the label: every ingredient is read against the rules. If the label leaves a question open, Know Halal searches the web for the maker's own written answer and for halal certifier listings. If nothing is published, we contact the company and ask.

What should I do when it says Doubtful?

Open Why & sources to see the exact question. Tap Contact manufacturer, then Ask Know Halal, to add your question, or email the company yourself. When the answer comes, you get a notification if you turned notifications on.

What if the barcode isn't found?

Know Halal searches the maker's and retailers' pages for it. If that finds nothing, take one photo of the ingredient panel. You get a verdict straight away, and the next person who scans it gets an answer too.

Do I need an account?

No. There is nothing to sign up for. The app makes a random device id so that answers to your questions can reach you.

Does it work outside the US and Canada?

Scanning works anywhere the product is in the databases, but the rules, certifiers and questions to makers are built for North America. Recipes differ by country, so a verdict for the US pack may not apply elsewhere.

How do I delete my data?

Clear history and cache, in Settings under Privacy, removes what is on your phone. To delete the anonymous records on our server, email [email protected] with the device id shown in the same place.
