EU ePrivacy Analytics Cookies

Decide whether need consent, whether a limited analytics exemption can be supported, and what evidence must prove the configuration.

Overview

are not automatically exempt from EU ePrivacy consent rules. The starting point is Article 5(3): storing information on, or accessing information from, a user's terminal equipment generally requires clear information and consent unless a narrow exemption applies. For analytics, teams need a documented technical classification, consent or exemption rationale, live banner behavior, and country-specific checks where national implementation or regulator guidance controls the final answer.

Section 1

When analytics cookies fall within Article 5(3)

Treat analytics as an whenever the website or app stores identifiers, reads cookies or local storage, sends client-side analytics events, uses tracking pixels or tracked URLs, or instructs browser code to send device-derived information to an analytics endpoint.

The technical scope is broader than classic browser cookies. EDPB guidance covers storage and access separately, client-side JavaScript calls, tracking pixels, tracked links, local processing that sends results back over the network, IP-based tracking in some circumstances, and unique identifiers in websites or mobile apps.

  • Inventory cookies, SDKs, pixels, local storage, ETags, tracked URLs, IP-only analytics, and unique identifiers used for measurement.
  • Record whether the site or a supplier instructs the browser, app, or device to send analytics information back over a public communications network.
  • Do not treat server logs, IP addresses, or first-party tooling as automatically outside Article 5(3); document why the information does or does not originate from terminal equipment.
  • Separate from authentication, security, shopping-cart, user-input, and preference cookies because purpose and implementation drive the exemption analysis.
Section 3

Assess national audience-measurement exemptions

Article 5(3) exemptions are narrow: WP29 identifies transmission-only storage or access and storage or access strictly necessary for a service explicitly requested by the user. Its finding that some first-party analytics presents lower privacy risk does not itself exempt that analytics. A national audience-measurement exemption needs its own source and configuration assessment.

CNIL's 11 June 2020 sheet describes a historical French opt-out model with the conditions listed below. Check the current French eligibility rules before relying on it. For audience-measurement trackers that already qualify for exemption, CNIL's recommendation consolidated on 16 January 2026 recommends user information, a tracker lifetime suitable for meaningful audience comparison, such as 13 months without automatic renewal on repeat visits, a maximum 25-month retention period for collected information, and periodic review. Those recommendations do not establish eligibility or an EU-wide retention rule.

  • The 2020 sheet limited purposes to audience measurement or A/B testing and excluded cross-checking with customer files, statistics on other sites, or other processing. Verify the purposes permitted by the current national rule.
  • The 2020 sheet required user information and an effective objection route. Record the information and user-choice controls required by the current national basis you rely on.
  • Check publisher scope and prevent cross-checking with other processing; the historical CNIL sheet limited the tracer to one site or application editor.
  • Treat last-byte IP truncation and the 13-month lifetime in the 2020 sheet as historical conditions, not a complete current eligibility test. Keep IP handling, tracker lifetime, and collected-data retention as separate evidence fields.
  • For a third-party processor providing comparative analytics to several publishers, document that data and trackers are collected, processed, stored, and separated independently for each publisher.
  • Ask the provider for its current assessment and configuration evidence, then check the deployed settings yourself. A vendor's privacy setting or exemption claim does not prove that your implementation meets the applicable national rule.
Section 4

Configuration and evidence requirements

The analytics decision should be reproducible from evidence, not from vendor labels. Keep the scanned cookie list, tag-manager rules, consent-management-platform configuration, event taxonomy, data-sharing settings, IP handling, retention settings, processor terms, and tests showing what fires before accept, after reject, after withdrawal, and after opt-out.

Consent logs matter when analytics is consent-based, but they are not the whole record. The team also needs proof that non-essential analytics is blocked until consent, reject and withdrawal choices are honored, and exempt or opt-out analytics remains within the exact configuration justified in the decision.

  • Save a cookie and tracer inventory with names, domains, purposes, lifetimes, first-party or third-party status, provider, data recipient, and trigger condition.
  • Capture CMP screenshots or configuration exports for the first layer, settings layer, analytics purpose text, accept control, reject control, save choices control, and withdrawal path.
  • Retain consent logs with timestamp, region, banner version, purpose version, user choice, withdrawal events, and a link to the policy text shown at the time.
  • Run evidence tests in at least four states: fresh visitor before choice, accepted analytics, rejected analytics, and withdrawn analytics.
  • For exemption claims, keep an engineering attestation mapping every condition in the current national eligibility source to the deployed configuration and data flows. Record permitted purposes, publisher separation, reuse restrictions, IP handling, tracker lifetime, and collected-data retention separately.
  • Refresh the record when analytics vendors, tag-manager containers, SDK versions, purposes, countries, user journeys, retention, or banner design change.
Section 5

What EU-wide sources cannot conclude alone

EU-level materials do not give a single operational answer for every analytics setup in every Member State. The ePrivacy Directive is implemented through national laws, national data protection authorities publish different levels of cookie guidance, and CNIL's analytics sheet itself warns that ePrivacy analytics guidance may be subject to national variation.

Do not state that a vendor, tag template, consent mode, or first-party analytics product is exempt across the EU merely because it can be configured with privacy controls. The final conclusion needs the actual configuration, the Member State position, and the evidence record.

Do always need consent under the EU ePrivacy Directive?

Consent is the starting point unless a narrow exemption applies to the actual deployment under the relevant Member State rules. WP29 requires a purpose-and-implementation analysis; its finding that limited first-party analytics can present lower privacy risk does not itself establish an exemption.

Can a team rely on CNIL analytics guidance for all EU countries?

No. CNIL is the French regulator, and the cited sheet is dated 11 June 2020 and flags national variation. Treat its conditions as a dated French example, then verify the current law and regulator guidance for every Member State relevant to the site or app.

What should consent logs prove for ?

They should prove the banner and purpose version shown, the user's affirmative choice or rejection, the timestamp and region, later withdrawal, and that analytics tags respected the choice in live tests.

  • Do not invent Member State analytics exemptions or retention limits where the cited sources do not contain that country rule.
  • Do not infer that all first-party analytics is strictly necessary; WP29 says purpose and implementation decide the answer.
  • Do not infer that opt-out analytics is lawful EU-wide from CNIL guidance alone.
  • Do not treat a vendor's privacy-preserving mode as evidence unless technical settings and live network behavior prove the claim.
  • Escalate when the site uses analytics for logged-in users, sensitive journeys, children, employee portals, health or financial services, cross-device measurement, or multi-controller data sharing.
