Terms of use
Last updated 11 August 2026
LabelRay is a free app that scans food barcodes and explains what is on the label using open data. These terms say what you can expect from it, and what it expects from you. They are short on purpose.
The app is free, and it is offered as it is
There is no charge, no subscription and no advertising. In exchange there is no warranty: LabelRay is provided as it is, it is currently in closed testing, and it may be unavailable, wrong, or discontinued. If it stops working you lose nothing you paid for.
It is not medical advice
Never rely on LabelRay alone if a food could harm you. The score is computed from open data that is often incomplete and sometimes wrong, and a field that is missing is not the same as a substance that is absent — the app says "no data" precisely because it cannot say "none".
This matters most for allergens. Recipes change, source data lags, and an allergen the app does not list may still be in the package. The label in your hand is the authority, and if you have a diagnosed allergy or a medical condition, so is your doctor.
Accounts
The app works without an account. Signing in with Apple or Google adds two things: your history follows you to a new phone, and you can contribute product data. You can delete the account at any time from inside the app, and what that removes is described in the privacy page.
Contributing product data
If you photograph a package to add or complete a product, three things apply:
- You must be allowed to take the photograph. Photograph packaging you have in your hands, not someone else's picture of it, and not a page out of a book or a website.
- What you send has to be what you see. Correct the extracted values against the label. Do not invent numbers, and leave a field empty when the package does not state it — empty means "not printed", and that is a useful answer.
- Approved contributions are published, and cannot be recalled. A moderator reviews every submission. Nothing is sent anywhere before that. Once approved, the facts and the front photograph go to Open Food Facts under an open licence, and open data is copied and mirrored by others, so no promise to withdraw it later would be honest. By submitting, you grant permission for that publication under terms compatible with CC-BY-SA 4.0.
Submissions may be rejected without explanation, and repeated deliberately false ones will cost you the ability to contribute.
The data, and who it belongs to
Product facts come from Open Food Facts and are used under the ODbL; product images are under CC-BY-SA. The product half of our own catalogue is published under the same ODbL terms, as an open export, which is how the share-alike obligation is met.
The score itself is ours: a deterministic calculation over those facts, not a figure taken from any source. It is not the same thing as the official Nutri-Score, and the app shows the two separately on purpose.
LabelRay is not affiliated with Open Food Facts, Apple, or Google.
Fair use of the service
Use the app as an app. Do not script it, scrape it, or try to pull the catalogue through the API — there is an open export for that, and it is faster than anything you could scrape. The service behind the app is one small server shared by everyone using it.
Changes
These terms may change; the date at the top moves when they do. If a change affects what happens to something you already submitted, it will not be applied backwards.
