# Default Behavior (No Explicit Consent Management)

> Understand how the Zeotap iOS SDK operates regarding consent when no specific consent mechanism is configured.

<Warning>
  **Important:** Please ensure your CMP configuration includes new **Vendor ID 1469** for 1st Party data tracking. Additionally, include **Vendor ID 301** if cookie sync is enabled. [Learn more](/articles/sdks/web-js/configurations/consent-options#shouldcheckzeotapvendorconsent)
</Warning>

This section describes the default behavior of the Zeotap iOS SDK when you initialize it **without** explicitly enabling consent management features (i.e., when the `useConsent` configuration option is `false`, which is its default value).

## How it Works

In this default mode, the SDK's tracking and data collection activities are primarily controlled by the `optOut` configuration option.

* **`optOut: false` (Default):**
  * If you initialize the SDK without specifying `useConsent: true` or `optOut: true`, the SDK assumes it has permission to operate fully.
  * It **will** track user activities (screen views, events).
  * It **will** process and store user identities provided via `setUserIdentities`.
  * It **will** send user properties and page properties.

* **`optOut: true`:**
  * If you explicitly set `optOut: true` during initialization, the SDK will be significantly restricted, effectively acting as a global "do not track" for the SDK in your app.
  * No tracking events will be sent to Zeotap.
  * User identification calls will be ignored.
  * All data collection functions will be disabled.

## Interaction with `setConsent` API

When the SDK is operating in this default mode (`useConsent: false`), calls to the `setConsent()` function have limited effect:

* The `track` parameter within the `setConsent` object is **ignored**. Setting it to `true` or `false` will have no impact on the SDK's tracking behavior, which remains governed by the `optOut` option.
* However, any **Brand Consents** included in the `setConsent` call (e.g., `{ "myBrandConsent": true }`) **will** still be processed, stored, and sent with subsequent events under the `z_p` query parameter of tracking requests.

## Example

```swift theme={null}
// SDK Initialization (Default Mode - Tracking Enabled)
// Initializes the SDK with default settings:
// useConsent: false (implied)
// optOut: false (implied)
// Tracking will be active by default.

var collectOptions = CollectOption()
    .writeKey(value: "YOUR_WRITE_KEY")
    .build()

Collect.initialize(option: collectOptions)

// The SDK will start tracking immediately after initialization
```

## Default Mode with OptOut

```swift theme={null}
// SDK Initialization with Global Opt-Out
var collectOptions = CollectOption()
    .writeKey(value: "YOUR_WRITE_KEY")
    .optOut(value: true) // Disable all tracking
    .build()

Collect.initialize(option: collectOptions)

// No tracking will occur, even if setConsent is called
Collect.getInstance()?.setConsent([
    "track": true // This will be ignored due to optOut: true
])
```

## Brand Consent in Default Mode

```swift theme={null}
// Even in default mode, brand consents are processed
var collectOptions = CollectOption()
    .writeKey(value: "YOUR_WRITE_KEY")
    .build()

Collect.initialize(option: collectOptions)

// Brand consents will be collected and sent
Collect.getInstance()?.setConsent([
    "track": false, // Ignored in default mode
    "newsletterOptIn": true, // This will be processed
    "marketingConsent": false // This will be processed
])
```

## When to Use Default Mode

**Recommended for:**

* Apps that don't operate under strict privacy regulations
* Internal/enterprise apps with pre-agreed data collection terms
* Apps in regions without explicit consent requirements
* Development and testing environments

**Not recommended for:**

* Apps distributed in EU/GDPR regions
* Apps subject to CCPA or similar privacy laws
* Consumer-facing apps that prioritize user privacy
* Apps that need granular consent management
