Piano Analytics

Analytics

Piano Analytics is the web and app analytics solution from Piano, formerly AT Internet. It measures audiences, traffic sources, content performance and conversions, with a privacy-focused setup. Its tag sets first-party cookies to recognize visitors; in France, a restricted configuration may qualify for the CNIL consent exemption, otherwise prior consent is required.

Overview

What does Piano Analytics do?

What is Piano Analytics

Piano Analytics is the digital analytics product of the Piano group, born from the acquisition of AT Internet, a French audience measurement pioneer. It collects pageviews, events and conversions from websites and apps and exposes them in dashboards used by editors, public sector bodies and large brands. Piano Analytics runs on European infrastructure and is one of the few solutions explicitly recognised by the CNIL as eligible for consent free audience measurement under specific configuration.

Data and cookies collected

Piano Analytics sets first party cookies on the site domain to identify the visitor (atuserid) and the session (atauthority) and to store basic configuration. By default it also captures the IP address, user agent, referrer, URLs visited, events and conversions. The exempted mode anonymises the IP at the edge, shortens the cookie lifetime and disables cross site or cross device matching.

GDPR and ePrivacy implications

Piano Analytics processes personal data because cookie identifiers and IP addresses qualify visitors. The default mode requires consent under article 5(3) of the ePrivacy Directive and article 6(1)(a) GDPR. In the CNIL exempted mode and provided the strict criteria are met, Piano Analytics can operate without consent on the basis of legitimate interest.

Consent and legal basis

In exempted mode the legal basis is article 6(1)(f) GDPR (legitimate interest of the publisher in measuring audience). In default mode the legal basis is article 6(1)(a) GDPR, the visitor consent obtained through a CMP that mentions Piano Analytics in the audience measurement or marketing category.

Data transfers

Piano Analytics data is processed on EU data centres, with French hosting available out of the box. Some peripheral Piano group services such as Composer or ID may run in the United States; check the regional configuration with the Piano support team and document the residency clauses in your DPA.

Practical compliance steps

Sign the Piano DPA, pick the EU data residency option, enable the CNIL exempted mode by default and switch to the default mode only after explicit consent. Use a first party CNAME for the collector, document the cookies and retention in the cookie policy and keep evidence of the exemption parameters in the record of processing.

Compliance

Piano Analytics and the GDPR

Piano Analytics is classified as “Analytics”. On a site that targets European visitors, it must only load after the visitor consents, and it must be listed in your cookie policy.

Legal basis
Article 6(1)(a) GDPR (consent) for the default cookie based mode; article 6(1)(f) GDPR (legitimate interest) is acceptable for the Piano Analytics exempted mode that follows the CNIL guidelines on consent free audience measurement.
Risk level
low
Applicable regulations
GDPR, ePrivacy Directive 2002/58/EC, French Data Protection Act and CNIL guidelines on cookies and audience measurement

Impact assessment (DPIA)

A DPIA is generally not required for Piano Analytics when used in CNIL exempted mode. It is recommended when Piano Analytics is combined with cross domain or cross device tracking, with detailed audience segments or with the wider Piano DMP.

Questions

Frequently asked questions about Piano Analytics

Can't find your question? Write to us, we answer fast.

Which cookies does Piano Analytics set?

In default mode Piano Analytics sets first party cookies on the site domain, typically atuserid (visitor identifier), atauthority (session) and atidvisitor (additional configuration). In CNIL exempted mode the cookies are shortened to a maximum 13 months retention and the identifiers are renewed on each session.

Is consent required to load Piano Analytics?

Consent is required in default mode under article 5(3) of the ePrivacy Directive. In the CNIL exempted mode, with the prescribed configuration (anonymised IP, no cross site or cross device matching, no advertising), Piano Analytics can be loaded without prior consent.

What is the legal basis for processing data through Piano Analytics?

In exempted mode the legal basis is article 6(1)(f) GDPR, legitimate interest of the publisher in measuring audience. In default mode the legal basis is article 6(1)(a) GDPR (consent). In both cases the publisher must inform users in the privacy notice and offer a right to object.

Does Piano Analytics transfer data to the United States?

Piano Analytics is hosted on EU data centres and does not transfer measurement data to the United States by default. Some peripheral Piano group products (Composer, ID, Personalization) may be operated from the US: confirm the regional setup with Piano and document any transfer with Standard Contractual Clauses.

Do I need a DPIA before using Piano Analytics?

A DPIA is not required for Piano Analytics used in CNIL exempted mode for plain audience measurement. It is recommended when Piano is combined with cross domain or cross device tracking, with detailed audience segments or with the rest of the Piano DMP, where the risk profile is higher.

How do I implement Piano Analytics in a GDPR compliant way?

Sign the Piano DPA, pick the EU region, enable the CNIL exempted configuration as your default and only switch to enriched analytics after explicit consent. Use a first party CNAME for the collector, integrate with your CMP and document the data flow and retention in the record of processing.

Are there alternatives to Piano Analytics?

Other EU friendly analytics products with similar positioning include Matomo, Plausible, Pirsch, Snowplow Self Hosted and AT Internet historic tags. Each tool has different trade offs in terms of CNIL exemption, granularity and ecosystem; Piano Analytics stands out for its enterprise grade reporting and its position with French public bodies.

How should I update the cookie policy for Piano Analytics?

List the Piano Analytics cookies (atuserid, atauthority, atidvisitor, optional atfirstvisit) with their name, purpose and retention. Distinguish the exempted mode (no consent required) from the default mode (after consent). Link to the Piano privacy notice and to your CMP preference centre.
