# 옵트아웃

옵트아웃이 활성화되면 SDK는 모든 이벤트 전송을 중단합니다.

## 초기화 시 설정

```javascript
const config = {
    optOutTracking: true
};
const hackleClient = Hackle.createInstance("YOUR_BROWSER_SDK_KEY", config);
```

## 런타임 옵트아웃 제어

```javascript
hackleClient.setOptOutTracking(true);
hackleClient.setOptOutTracking(false);
const isOptOut = hackleClient.isOptOutTracking();
```

## 영속성 관리

{% hint style="warning" %}
페이지 새로고침 또는 재방문 시 Config에 설정된 값으로 리셋됩니다.

페이지 새로고침 시 상태를 유지하려면 직접 저장 및 복원 로직을 구현해야 합니다.
{% endhint %}

```javascript
function saveOptOutState(optOut) {
    localStorage.setItem("hackle_opt_out", JSON.stringify(optOut));
    hackleClient.setOptOutTracking(optOut);
}

function getOptOutConfig() {
    const optOut = JSON.parse(localStorage.getItem("hackle_opt_out") || "false");
    return {
        optOutTracking: optOut
    };
}

const config = getOptOutConfig();
const hackleClient = Hackle.createInstance("YOUR_BROWSER_SDK_KEY", config);
```
