## What is AllergenScan?

AllergenScan tells you in seconds whether a food is safe for you or your family — before it ends up in the cart.

Scan a barcode or photograph an ingredient label. AllergenScan checks against your personalized allergy profile and delivers a clear Safe, Caution, or Danger verdict with color-coded results you can read at a glance.

BUILT FOR FAMILIES WITH FOOD ALLERGIES
• Create up to 6 individual allergy profiles - one for each family member
• Switch profiles instantly while shopping
• Track gluten, dairy, peanut, tree nuts and more for every child
• Grandparents and caregivers can shop confidently for allergic children

SMART ALLERGEN DETECTION
• Recognizes 9 FASTER Act allergens plus 25+ extended allergens
• Identifies hidden allergen names (e.g., "casein" = milk, "lecithin" = soy)
• Cross-contamination risk grading: interprets "may contain" and "shared facility" warnings based on YOUR severity level

WORKS WHEN YOU NEED IT
• Offline-first: allergen matching runs 100% on-device
• Scanned products are cached - no signal required in the store
• Emergency card with one-tap 911 and caregiver call buttons, available on your lock screen

SAFE LIST & BLACKLIST
• Build a personal library of confirmed-safe products
• Blacklist dangerous items so you never second-guess
• Share your lists with family, schools, and caregivers

DESIGNED FOR PEACE OF MIND
• Large, bold verdicts: Green (Safe), Amber (Caution), Red (Danger)
• Triple-signal communication: color + icon + text (accessibility-first)
• One-handed operation optimized for supermarket conditions

FREE TO START
• 3 free scans per day - no account required
• Upgrade to Premium for unlimited scans, OCR ingredient reading, cross-contamination analysis, offline mode, recall alerts, and complete scan history

AllergenScan is not a substitute for reading product labels. Always verify ingredients directly, especially for severe allergies. Consult your allergist for medical advice.
