Must Google Analytics 4 be disclosed in a privacy policy?

Yes. Google Analytics 4 must be disclosed because it collects personal data including IP addresses, device identifiers, and behavioral information. Under GDPR, CCPA, and similar regulations, websites must transparently inform users about all analytics tools processing their data. Failure to disclose Google Analytics 4 violates privacy regulations and user trust principles.

What specific data does Google Analytics 4 collect?

Google Analytics 4 collects IP addresses (anonymized by default), pages visited and navigation paths, session duration and engagement time, device type/browser/operating system, geographic location (country and city level), referral sources and campaign parameters, and screen resolution. This data is transmitted to Google's servers to generate analytics reports and audience insights.

Does Google Analytics 4 require a cookie consent banner?

Yes, under GDPR and similar regulations, explicit user consent is required before Google Analytics 4 activates. Google Analytics 4 uses cookies (_ga and _ga_* cookies with 2-year expiration) to track users across sessions. Websites must implement a consent management platform that allows users to accept or reject analytics tracking before cookies are set.

Who processes Google Analytics 4 data and where is it stored?

Google LLC, headquartered in the United States, is the data processor. User data collected by Google Analytics 4 is transferred to and processed on Google's servers in the US. The EU-US Data Privacy Framework governs this transfer for EU users. Websites should ensure appropriate data processing agreements (Data Processing Amendments) are in place with Google.

Forgetting to disable IP anonymization transparency or miscommunicating it

GA4 anonymizes IP addresses *by default*, but many operators don't disclose this to users—or worse, believe anonymized IPs exempt them from GDPR. The mistake: Treating anonymized data as outside GDPR scope. Why it happens: The term "anonymization" sounds like safe harbor, and Google's documentation emphasizes the default setting. Consequence: If audited, regulators will ask for your anonymization methodology (hashing, truncation, salting). If you can't prove irreversible anonymization per GDPR Recital 26, the data is still personal data. You lose the claimed exemption and face back-compliance liability.

Misconfiguring consent in GA4 settings

GA4 allows you to set consent modes (`ad_storage`, `analytics_storage`) via gtag.js. The mistake: Enabling the GA4 tag unconditionally and *then* trying to apply consent mode retroactively, or failing to map consent categories correctly. Why it happens: Developers often treat GA4 as "fire first, ask permission later." Consequence: Under GDPR Article 6 and ePrivacy Article 5(3), processing without prior consent is unlawful. Regulators will find non-consensual data collection in server logs and impose fines. CCPA also requires opt-out mechanisms that block GA4—not providing one invites California AG enforcement.

Missing the Data Processing Agreement (DPA) with Google

Google LLC is a data processor under GDPR Article 28. The mistake: Not signing Google's DPA (available in Google Analytics settings under "Data Protection Terms"). Many founders assume Google handles this automatically. Why it happens: The DPA is optional-looking in the UI and not prominent. Consequence: Operating without a signed DPA is a direct GDPR Article 28(3) violation. Auditors flag this immediately. The fine threshold is lower for procedural violations (missing paperwork) than data breach fines, but still material—and it's indefensible because the remedy is a checkbox.
