Privacy and Compliance Considerations When Using GA4 Parameters

When using Google Analytics 4 (GA4) parameters, key privacy and compliance considerations include automatic IP anonymization, data retention limits, explicit user consent, and transparent data sharing policies.

GA4 automatically anonymises IP addresses by default and does not store them, which significantly reduces the risk of collecting personally identifiable information (PII) and helps comply with privacy laws such as GDPR. This default IP anonymization cannot be disabled, ensuring that user IPs are not stored or used to profile individuals.

GA4 also limits user-level data retention to a maximum of 14 months, reducing the amount of stored personal data and exposure to potential data breaches compared to previous versions.

Explicit user consent is generally required before collecting analytics data, especially in jurisdictions with strict privacy regulations. This means websites must update their privacy policies to clearly disclose data sharing with GA4 and obtain consent prior to data collection to avoid legal violations. Analytics data collection is not considered a “legitimate interest” under many data protection authorities, so consent is necessary.

Data sharing settings in GA4 should be carefully configured to limit unnecessary sharing, and businesses should accept GA4’s data processing terms to ensure compliance. Additionally, if Content Security Policies are used, appropriate allowances must be made for GA4’s data collection domains to function correctly.

In summary, the main privacy and compliance considerations when using GA4 parameters are:

• IP anonymization enabled by default, no IP storage
• Limited user data retention (up to 14 months)
• Requirement for explicit user consent before data collection
• Clear, updated privacy policies reflecting GA4 data use
• Proper configuration of data sharing and processing terms
• Technical allowances for GA4 domains in security policies

These measures help businesses use GA4 while respecting user privacy and complying with applicable data protection laws.
