How this works: while you're live, your name, emoji and approximate location are visible to other live users through an open public relay, sorted nearest first. Nothing is saved — no account, no history. Close the page and you vanish completely. Don't type anything private here. Treat offers are a friendly gesture settled at the table — LunchMeNow never handles money.
