Frequently asked questions

A barcode is not recognised

Product availability depends on the connected databases. Please check the barcode and try again later. Unknown barcodes may be recorded anonymously so that database coverage can be improved.

The displayed information appears incorrect

Please send the barcode, product name and a brief description of the issue to the support email address. A photo of the packaging can also help, but please avoid including personal information.

How do I manage or cancel a subscription?

Subscriptions purchased on iPhone or iPad are managed through your Apple ID subscription settings. MegaCheck and RevenueCat do not receive your full payment-card details.

How do I request deletion of app-related data?

Email us with the subject “Data deletion request”. Please include the information needed to identify the relevant anonymous account or installation where available. Some purchase records must remain with Apple or other providers under their own legal obligations.
