That card is an ad. Ads are how Lume stays free: sponsors pay, so you never have to. Sponsored cards are always labelled "Sponsored", so you can tell them apart from answers at a glance.

When an ad is requested, your question and the answer you were shown are sent to Koah, Lume's ad partner, so it can pick something relevant to the conversation. Koah handles what it receives under its own privacy policy. Nothing else about you or your account is sent.

Your data is never sold, and your chats are never used to train AI models. Ads only appear if you told Lume you are 18 or over. If there is no relevant ad to show, Lume simply shows nothing.
