# CCPA - Privacy String

The California Consumer Privacy Act of 2018 ([CCPA](https://iabtechlab.com/standards/ccpa/)) protects the personal information of California residents. It applies to all businesses operating in California. If a California resident uses an app developer's mobile app, CCPA applies to the developer and all relevant partners that process users' personal information.

## Setting the IAB US Privacy String

DT recommends that the first time you gather a user's opt-out (consent), pass it to the SDK before initializing it. The SDK considers the user's opt-out when initializing.

To set the IAB US privacy string using the following API:

{% tabs %}
{% tab title="Android" %}
{% code title="Java" %}

```java
String privacyString = "1YNN";
UserInfo.setIabUsPrivacyString(privacyString, context);
```

{% endcode %}
{% endtab %}

{% tab title="iOS" %}
{% code title="Swift" %}

```swift
FairBid.user().iabusPrivacyString = "1YNN"
```

{% endcode %}

{% code title="Objective-C" %}

```objective-c
[FairBid user].IABUSPrivacyString = @"1YNN";
```

{% endcode %}
{% endtab %}

{% tab title="Unity" %}
{% code title="C#" %}

```csharp
var privacyString = "1YNN";
    UserInfo.SetIabUsPrivacyString(privacyString);
```

{% endcode %}
{% endtab %}
{% endtabs %}

To determine what value to use for the US Privacy String, see [IAB US Privacy String](https://github.com/InteractiveAdvertisingBureau/USPrivacy/blob/master/CCPA/US%20Privacy%20String.md).

Valid values include:

* `1---`: CCPA does not apply, for example, the user is not a California resident.
* `1YNN`: User does NOT opt out, ad experience continues.
* `1YYN`: User opts out of targeted advertising.

## Clearing Privacy Opt-Out

To clear the user opt-out setting, use the following API:

{% tabs %}
{% tab title="Android" %}
{% code title="Java" %}

```java
UserInfo.clearIabUsPrivacyString(context);
```

{% endcode %}
{% endtab %}

{% tab title="iOS" %}
{% code title="Swift" %}

```swift
FairBid.user().clearIABUSPrivacyString();
```

{% endcode %}

{% code title="Objective-C" %}

```objective-c
[[FairBid user] clearIABUSPrivacyString];
```

{% endcode %}
{% endtab %}

{% tab title="Unity" %}
{% code title="C#" %}

```csharp
UserInfo.ClearIabUsPrivacyString();
```

{% endcode %}
{% endtab %}
{% endtabs %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.digitalturbine.com/dt-fairbid/fairbid-sdk/sdk-reference/ccpa-privacy-string.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
