Why contribute
Every region has products the catalog doesn't know yet. When you've already done the work of entering one accurately, sharing it means the next person who scans that barcode finds it instantly instead of typing the label all over again.
How it works
There is one way in, and it starts with the packaging: build the food by scanning a barcoded nutrition label, and it arrives with Contribute to the catalog already on — the barcode and the label are what make a submission checkable. A food you type in by hand stays personal and can't be contributed at all. You'll be able to attach two photos: Product front and Nutrition facts. The front one isn't decoration — it visibly speeds up approval. Worth knowing before you send them: those photos may be made public to improve the shared catalog, and they are not kept on your own copy of the food.
Every submission is reviewed by a person before it joins the public catalog; nothing goes live automatically.
What's shared — and what never is
Only the food's information travels: name, brand, barcode, serving, and nutrition facts, plus the packaging photos you attached. Nothing about you — not your name, not your diary, not anything else from your account — is part of a contribution.
Changing your mind
You can turn the toggle off at any time. If the food hasn't been approved yet, the submission is withdrawn automatically. Your own copy of the food stays in My Foods regardless — contributing never affects your ability to use it.
