## What is Microsoft Clarity?

Microsoft Clarity is a free behavioral analytics tool that helps website owners understand how visitors interact with their sites through features like session recordings and heatmaps.

## The October 2025 Deadline

Starting **October 31, 2025**, Microsoft Clarity will begin enforcing consent requirements for visitors from the EEA, United Kingdom, and Switzerland.

## Data Clarity Collects

### Cookies Used

- `_clck` - Stores a unique user ID (12 months)
- `_clsk` - Connects page views into a session (1 day)

### Data Categories

1. **Analytics Storage** (`analytics_Storage`) - Session recordings, heatmaps, user behavior tracking
2. **Ad Storage** (`ad_Storage`) - Required when Clarity data is connected to advertising platforms

## The consentv2 API

```javascript
window.clarity = window.clarity || function(){
  (window.clarity.q = window.clarity.q || []).push(arguments);
};

window.clarity('consentv2', {
  'ad_Storage': 'granted',
  'analytics_Storage': 'granted'
});
```

> **Warning: Important: Case Sensitivity**
>
> Clarity uses capital S in `ad_Storage` and `analytics_Storage`. This differs from Google's lowercase versions.

## Integration with Microsoft Advertising (UET)

```javascript
// Microsoft UET uses different API
window.uetq = window.uetq || [];
window.uetq.push('consent', 'default', {
  'ad_storage': 'denied'
});

// Microsoft Clarity
window.clarity('consentv2', {
  'ad_Storage': 'denied',
  'analytics_Storage': 'denied'
});
```

## How CookieBeam Handles This

CookieBeam automatically manages Microsoft Clarity consent mode when you enable Microsoft Consent Mode in your banner settings.

> **Tip: Enable Microsoft Consent Mode**
>
> In your CookieBeam dashboard, go to Banner Settings and enable Microsoft Consent Mode to automatically handle consent for both UET and Clarity.
