Possibly - and in today's world I'd even go with "probably." The "scan a UPC and get the 'how to cook'" needs some external access. I haven't decoded the QR code to determine if the recipe instructions is encoded in there, or if that's a lookup - I suspect its encoded rather than a lookup (and the QR code based meals appear to work without wifi).

The database, however, would only be useful/of the UPCs and raw ingredient based that you scan rather than the meal plan since with a meal subscription service, they've already got that data. And as a regular toaster oven, doing "bake 375°" isn't leaking any data about what you are eating.
