Questions

HistaScan FAQ

What is HistaScan?

HistaScan is an iPhone app for people with histamine intolerance (HIT) or mast cell activation syndrome (MCAS). It scans barcodes, ingredient labels, menus, and meal photos for potential histamine triggers and includes a symptom diary.

How does HistaScan rate foods?

Each ingredient is rated Safe, Caution, or Trigger using the widely referenced SIGHI histamine compatibility list, with a plain-language reason and a lower-histamine swap when a trigger appears.

Can I check restaurant menus and home-cooked meals?

Yes. Scan menu or ingredient text with your camera, or photograph a dish to analyze the whole meal.

Is HistaScan free?

HistaScan is free to start. Premium adds unlimited scans, instant meal-photo analysis, and advanced symptom insights.

Is my health data private?

No account is required. Your diary, reaction logs, saved foods, and scan history are stored only on your device. Ingredient text, barcodes, and meal photos you choose to analyze are sent to our analysis providers without any name, email, or device identifier, and nothing is used for advertising.

Is HistaScan medical advice?

No. HistaScan is an educational tool and not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider.
