! In an emergency
AllerTrac is not an emergency tool. If you or someone in your care is having a severe allergic reaction (for example, difficulty breathing, swelling, or anaphylaxis), use your emergency medication (such as an epinephrine auto-injector) if prescribed and contact your local emergency services immediately. Do not rely on the app in an emergency.
1 What AllerTrac does
AllerTrac compares the ingredients, “may contain” notes, and shared-facility statements available for a product against the avoid-list you configure for each profile. Matching is performed by a deterministic rule engine: the same inputs always produce the same result. Artificial intelligence is never the authority for a risk result; at most it helps read or propose text, which you review.
Every result names the exact triggering ingredient, where it was found (ingredient list, “may contain”, or shared facility), the data source, and a confidence level.
2 The four result states
AllerTrac never says a product is “safe”, “approved”, or “all clear”. Instead it uses four states:
3 How confidence is determined
Confidence reflects the quality and freshness of the underlying data — for example, a recently verified barcode-database entry with a full ingredient list yields higher confidence than a sparse list or a low-quality label photo. A confidence level and, where available, a percentage are shown with every result.
4 Important limitations — please read
- Data can be wrong or stale. Product databases (including crowd-sourced sources such as Open Food Facts) can be incomplete, outdated, or incorrect. Manufacturers change formulations without notice.
- OCR is imperfect. Photographing a label can misread small, glossy, curved, or low-contrast text. Low-confidence reads are reported as “Review” or “Not enough information”, not guessed.
- “No flagged ingredients found” ≠ safe. AllerTrac cannot detect cross-contamination it is not told about, cannot account for your individual tolerance thresholds, and cannot catch an allergen that is mislabelled or absent from the available text.
- Source conflicts default to caution. When barcode/database data and the printed label disagree, AllerTrac asks you to trust the printed package and review.
- Your configuration matters. Results are only as complete as the avoid-list and strictness settings you configure for each profile.
- Not a medical device. AllerTrac provides organisational and ingredient-matching assistance only. It is not a medical device and does not provide medical advice, diagnosis, or treatment.
5 Your responsibility
You are responsible for your final decision about any product. Always read the printed package label before purchasing or consuming a product, and consult a qualified healthcare professional (such as an allergist) for medical advice about allergies, sensitivities, and emergency planning.
6 Reporting data problems
If you find wrong or missing ingredient data on a product, use “Report an issue” from any result, or email support@allertrac.com. Corrections help improve the underlying data but do not change your responsibility to verify the label.
