opt out

Choose against joining

Opt out is to choose not to participate in something, especially when participation is the default: You can opt out of marketing emails at any time.

The phrase implies declining rather than actively refusing—withdrawing from something you'd otherwise be included in.

The noun opt-out names the choice or mechanism: There's an opt-out at the bottom of the page.
