Formula Collection license questions

Does one purchase include both Soboro and Sweet Red Bean Buns?

Yes. This paired collection includes one shared dough, peanut streusel and sweet red bean filling, with production methods for both products. The USD 99 price covers this collection and its offline calculator.

Can I sell the finished buns?

Yes. The included license allows physical products through one bakery operation at one physical location. You remain responsible for local commissioning, food safety, allergens, shelf life, labelling and licensing. Digital files may not be resold, redistributed or published.

Does the calculator require a subscription?

No. Unzip the download, keep the HTML and JavaScript files together, and open the HTML in a current browser. Enter your batch and actual costs, save entries locally and print a batch sheet. Cost examples are clearly marked invented scenarios.
