A batch tag shares what a buyer needs to trust their food, and nothing more.
A public batch tag shows the farm it came from, the harvest date, and its treatment history. It never shows a grower's personal details, exact home address, or financial data. Growers decide what's visible on a public tag before it's ever printed.
Anyone scanning a tag does so without creating an account, so there's nothing tying a shopper's, chef's, or diner's identity to the batches they check.
