Free-scan allowance and fraud prevention
Eligible users currently receive five free food-label scans for the lifetime of their free allowance. Deleting an account, reinstalling Luonio, resetting App data, changing devices, or receiving a new anonymous account does not restore or create additional free scans. Limited account, device, usage, transaction, and technical signals may be used to enforce eligibility and prevent circumvention, fraud, or abuse, as described in our Privacy Policy and Terms of Use.
Help center
Common questions.
Why can’t Luonio read my label?+
Make sure the image is sharp, evenly lit, and includes the full ingredient list. Avoid glare, shadows, curved packaging, and cropped text. Because OCR and automated analysis can make mistakes, always verify the result against the current packaging.
Does an unsuccessful scan use my allowance?+
A scan may count when processing begins or server resources are committed, including when a label is unreadable or a connection is interrupted after submission. Contact support if you believe a scan was counted because of a technical problem.
How do I restore Luonio PRO?+
Go to Settings → Restore Purchase and make sure you are signed in with the Apple Account used for the original purchase. Temporary Apple, RevenueCat, or network verification issues may delay restoration.
How do I cancel my subscription?+
Manage or cancel Luonio PRO through your Apple Account subscription settings. Deleting the App or your Luonio account does not cancel an active subscription.
What is the Luonio PRO scan allowance?+
An active PRO subscription currently includes up to 50 food-label scans per calendar day. Unused scans do not roll over, and reset timing follows the Services’ technical timekeeping method.
How do I delete my account?+
Open Luonio and go to Settings → Delete Account. Account deletion removes the current anonymous authentication account and associated information is deleted or scheduled for deletion under our retention practices. It does not cancel an App Store subscription or reset free-scan eligibility.
How do I report an incorrect result?+
Use Report an Issue on the result screen when available, or email support. Include a brief explanation and the relevant label image if appropriate. Do not include unnecessary personal or sensitive information.
Can I rely on Luonio for allergies or medical decisions?+
No. Luonio is an informational tool, not a medical device, allergy-verification service, or substitute for professional advice. Always check the current packaging and consult a qualified healthcare professional when appropriate.
