AllerTrac is a camera-first allergy assistant that checks a product against your whole household — and traces every answer back to the exact ingredient and data source it used.
AllerTrac never says a product is “safe” or “approved.” Every scan returns one of four honest result states — always paired with an icon, a label, the matched allergy, and the exact evidence behind it.
Set up a profile for each person, each with its own allergy list and strictness. A single scan is evaluated against everyone — so one result shows who's clear and who's flagged.
Results come from a transparent, deterministic rule engine — not a black-box guess. AI only helps read and normalize text you can review; it's never the authority on a result.
False negatives are the number-one risk in an allergy tool, so AllerTrac is designed around them. When data is missing, conflicting, or low-quality, it says so — and asks you to review — rather than guessing in your favour.
A built-in ontology recognises not just direct names, but derivatives and vague “may contain” terms, with synonyms expanded across the top-9 allergens.
Live product lookups come from Open Food Facts (cached for 30 days), with a labelled local catalog as a fallback only when no live data is available.
Review past scans and their results whenever you need to look something up again.
Build and manage lists for groceries you're planning to buy.
Keep track of the items you already have at home.
Surface products with no flagged ingredients for the active profile.

Accessible typography with Atkinson Hyperlegible for safety-critical text.
AllerTrac is a trust product. Profiles, avoid-lists, scans, and lists live in your own account — readable only by you.
Each account can read and write only its own data. Product and ontology data is read-only.
Allergy names, profile names, label text, and barcodes are never included in analytics or used for ads.
Ingredient-label photos are processed on your device, and uploaded only if you choose to save them.

No. AllerTrac never labels a product “safe,” “approved,” or “all clear.” It reports whether your configured avoid-list items appear in the available text, using four honest states, and always shows the evidence. The final decision — especially for severe allergies — is always yours.
Scan a barcode with the camera, photograph an ingredient label (read on your device with on-device text recognition), or search by product name. When barcode data and a label scan disagree, AllerTrac returns “Review before using” rather than guessing.
Yes. Create a profile per household member with its own avoid-list and strictness, and a single scan is evaluated against every profile — so one result shows who's clear and who's flagged.
In your own account, readable only by you. Allergy names, profile names, label text, and barcodes are never sent to analytics or used for advertising. You can delete your account and all of its data at any time.
No. Results come from a transparent, deterministic rule engine — the same inputs always produce the same result. AI is limited to extracting, normalizing, and explaining text you can review; it is never the sole authority on a result.

AllerTrac is an ingredient-matching assistant. It does not diagnose, treat, cure, or prevent any condition, and it does not determine whether a product is safe. Results depend on available ingredient text, OCR quality, product-data freshness, and your configured avoid-list. Always read the printed package label and consult a qualified healthcare professional for medical advice. In an emergency, use prescribed medication and contact your local emergency services.
