Forge, NeoForge, Fabric and Quilt — read in this tab, never uploaded.
Nothing is uploaded. Before anything is shown, home directories, IP addresses, account UUIDs and token-shaped fields are masked — but read it before you paste it anywhere public, because a mod can print anything in a format no filter knows.
This is the one page on this site that asks a third party for something: the status query goes to a public Minecraft status API, so the address you type leaves your browser. Check servers you run or intend to join — not address ranges.
