opt-in/opt-out

Opt-in and opt-out are terms used to describe how individuals give or revoke permission for certain actions, like sharing personal data. Opt-in means you must actively agree or consent before something happens—like signing up for a newsletter. Opt-out means you are automatically included unless you choose to decline or cancel—such as being enrolled in an email list unless you unsubscribe. These options give people control over their choices, ensuring they can decide whether they participate or not, depending on their preferences for privacy, marketing, or other services.
