Frequently asked questions
Manage your subscription
Subscriptions are handled by Apple or Google, not by Gulio. Cancel or change your plan from your store account.
How do I cancel my subscription?
On iPhone: Settings → your name → Subscriptions → Gulio → Cancel. On Android: Google Play → Profile → Payments & subscriptions → Subscriptions → Gulio → Cancel. Cancelling stops auto-renewal; your access continues until the end of the paid period.
I've used my 5 free scans. What now?
The free plan includes 5 scans and 3 top product categories. Upgrade to Premium in the app for unlimited scanning, multiple profiles, analytics and faster support.
A product shows the wrong result.
Analysis relies on product databases and text recognition, which can be incomplete. Please email us the product name, barcode and a photo of the label and we'll review it. Always verify the packaging before eating.
Is the FODMAP feature certified?
No. Low-FODMAP support matches ingredient text against a large keyword list of high-FODMAP ingredients. It is not a certified FODMAP database and should not replace professional guidance.
How does the restaurant finder use my location?
Your location is used on your device to search nearby places while the feature is open. You can revoke location access at any time in your phone's settings; the scanner keeps working without it.
How do I delete my account and data?
In the app, open Settings → Account → Delete account. This removes your profiles and scan history. You can also email us and we'll delete your data within 30 days.
Which languages are supported?
English, French, German, Italian, Japanese, Portuguese and Spanish. The app follows your phone's language.
Can I request a refund?
Purchases are processed by Apple or Google, and refunds follow their policies. Request one from your App Store purchase history or Google Play order history. We're happy to help if you get stuck.
