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

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

The consentv2 API

1 window.clarity = window.clarity || function(){
2   (window.clarity.q = window.clarity.q || []).push(arguments);
3 };
4 
5 window.clarity('consentv2', {
6   'ad_Storage': 'granted',
7   'analytics_Storage': 'granted'
8 });

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)

1 // Microsoft UET uses different API
2 window.uetq = window.uetq || [];
3 window.uetq.push('consent', 'default', {
4   'ad_storage': 'denied'
5 });
6 
7 // Microsoft Clarity
8 window.clarity('consentv2', {
9   'ad_Storage': 'denied',
10   'analytics_Storage': 'denied'
11 });

How CookieBeam Handles This

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

Enable Microsoft Consent Mode
