Frequently Asked Questions

How does GutGuard analyse ingredients?

GutGuard uses a seven-mechanism framework grounded in peer-reviewed research. When you scan a label, each ingredient is evaluated for its impact on gut barrier integrity, microbiome balance, and inflammation pathways. The analysis covers emulsifiers, refined seed oils, artificial sweeteners, nitrites, refined carbohydrates, AGEs, and flavour enhancers.

Is GutGuard medical advice?

No. GutGuard is an educational tool that helps you understand what's in your food. It is not a substitute for professional medical or dietary advice. If you have specific health concerns, please consult a qualified healthcare professional.

Do I need an account?

No. GutGuard works without any account or sign-in. Your analysis history is stored locally on your device and is never uploaded.

How do I try GutGuard?

GutGuard offers a free trial as part of the annual plan. Start your trial to get full access to all features. You can cancel at any time during the trial period without being charged.

How do I manage or cancel my subscription?

Subscriptions are managed through Apple. Go to Settings > Apple ID > Subscriptions on your iPhone, or visit apps.apple.com/account/subscriptions. You can cancel at any time and retain access until the end of your billing period.

How do I restore my purchase on a new device?

Open GutGuard, go to Settings, and tap Restore Purchases. Make sure you're signed in with the same Apple ID you used to subscribe.

Why does GutGuard need camera access?

Camera access is only used to photograph ingredient labels for analysis. Photos are processed and then discarded. They are not stored on our server or shared with anyone.

Is my data private?

Yes. There are no accounts and no way to identify who you are. Your analysis history is stored locally on your device. Scan records are saved on our server to improve analysis quality, but they are linked only to an anonymous session ID. Our analytics are aggregated and cannot identify individual users. Read our full privacy policy for details.
