From the article:

Customers (91 individuals): Delivery address, name, phone number, date of purchase, and product name for items requiring delivery and installation.

And if you’re wondering what Casio products require installation, they also make medical imaging hardware and POS terminals.

So it sounds to me like b2b stuff and employee databases rather than anything consumer related.

Probably that. I was out here wondering who was giving data to the calculator company.
