Open the Premium screen in the app (Settings → Go Premium) and tap Restore Purchases. Make sure you are signed in with the same Apple ID that made the original purchase.
A Chef Fresh subscription is linked to one Chef Fresh account. Sign in with the account you originally used and restore purchases there to keep using Premium with it.
Subscriptions are managed by the App Store, not inside the app: open the iPhone Settings → your name → Subscriptions, pick Chef Fresh, and tap Cancel. Deleting the app or your account does not cancel a subscription.
Ask the kitchen owner for an invite code, then open Shared Kitchen, enter the code, and tap Join. Joining is always free; creating invites requires Premium.
Try a clearer, well-lit photo taken straight on, or add a short note about what you bought. Attempts that return no items are not counted against your scan allowance.
Open Settings → Account → Delete Account. This permanently removes your cloud data. See the Privacy Policy for details on what we store.
