Data Retention in Google Analytics 4


The arrival of Google Analytics 4 (GA4) marks a paradigm shift in data analysis. While its predecessor, Universal Analytics, offered indefinite data storage, GA4 adopts a dynamic approach with a default 14-month retention period. But don’t let this seemingly short timeframe deter you! GA4 empowers you to optimize data retention, unlock real-time insights, and fuel data-driven decisions like never before.

Why Master Data Retention in GA4?

  • Protect Historical Insights: Retain valuable data for long-term trend analysis, performance evaluation, and regulatory compliance.
  • Beyond 14 Months: Don’t lose crucial information. Customize retention periods to suit your needs.
  • Real-Time Analysis Powerhouse: Uncover deeper insights faster with seamless integration of GA4 with tools like Google BigQuery and Looker Studio.

Optimizing Your GA4 Data Retention Strategy

  1. Navigate and Access: Log in to your GA4 property and head to Admin Settings > Data Settings > Data Retention.
  2. Choose Your Timeframe: Opt for 2 months, 14 months, or explore Google Analytics 360 options for extended periods.
  3. Save and Unleash Potential: Click “Save” to unlock GA4’s full potential and transform data into actionable insights.

Understanding User and Event Data Retention

The retention framework focuses on data tied to identifiers such as cookies, User-IDs, and advertising identifiers like DoubleClick cookies and mobile device IDs (AAID/AdID, IDFA). Notably, specific data types like age, gender, and interests are automatically purged after a set period of inactivity—six months for Universal Analytics and two months for GA4 properties.

Configurable Retention Periods for GA4

In Google Analytics 4, retention settings allow for customization, offering options for user-level and event-level data retention:

  • For user-level and conversion data:
    • 2 months
    • 14 months
  • For all other event data:
    • 2 months
    • 14 months
    • Extended options for 360 users: 26, 38, or 50 months
