      FAQ

      Where does the nutrition data come from?

      Protein values are averages sourced from USDA FoodData Central, used for gameplay purposes. They're not verified medical or dietary advice. See the legal notice.

      How is a Hard Mode plate's protein value calculated?

      It's the sum of every visible ingredient on the plate, scaled to its portion, not just one main ingredient. A plate with eggs, bacon, and toast adds up the protein from all three.

      Is Protein Duel free?

      Yes, completely free, no account, no ads, no in-app purchases.

      Does my streak sync across devices?

      No. Your best streak is stored only in your browser's local storage. Clearing your browser data resets it. See the privacy policy.

      Are there any easter eggs?

      Yes, a few. Some show up when you hit certain streaks, others hide behind buttons you'd never think to press. We won't spoil them, go find them.
