Everything here runs in this tab. Your program is compiled and executed by a WebAssembly build of the Origin compiler inside your own browser. It is never uploaded, and no server — including the one that served this page — ever sees it or runs it.

Your program is kept in this browser’s local storage so it is still here when you come back. It stays on this device, is not synced anywhere, is not visible to whoever runs this site, and is lost if you clear site data.

Copy link puts the whole program in the link itself, after the #, which browsers never send to a server. Nothing is stored, so a link cannot expire or be taken back — whoever has it has a copy of the program.
