What is the difference between opt-in and opt-out consent?

The difference is when the user’s action is required.

Approach

How it works

Opt-in

Processing waits until the user actively agrees

Opt-out

Processing may occur unless the user objects or disables it

Opt-in consent is used where prior affirmative permission is required. Opt-out mechanisms are common for rights such as stopping targeted advertising or data sharing under some U.S. privacy laws.

The correct model depends on the applicable law and purpose; they are not interchangeable.
