The database is free. Forever.
Every food, every nutrient, every compound, every claim, every evidence rating, every citation and every caveat is available without an account. We are never going to paywall a health fact — the moment a free page gets worse to sell an upgrade, the whole thing is compromised.
Premium buys tools on top of that data, for people who use Know2Eat constantly.

Billing has not been switched on, so there is nothing to buy here — we would rather show you an honest empty state than a button that pretends to take a payment. The features above are built and the limits are enforced; only checkout is missing.
Why the data stays free
A site that hides an interaction warning or a downgraded evidence rating behind a subscription is worse than useless — it is actively dangerous. So the split is deliberate and permanent: facts are free, convenience is paid. If you ever find a health fact on Know2Eat behind a paywall, treat it as a bug.
