What This Script Does

The Gemius script collects page view data, session information, and demographic indicators from visitors. It sets cookies to identify unique browsers and track return visits across measurement sessions. Network requests transmit page URLs, timestamps, referrer data, and browser metadata to Gemius servers. The collected data generates audience reports including reach, frequency, and demographic breakdowns used in cross-publisher media planning.

Consent & Compliance

Gemius falls under the analytics consent category. Its scripts set persistent cookies for visitor identification, which requires opt-in consent under GDPR and the ePrivacy Directive. As Gemius operates primarily in EU/EEA markets, GDPR compliance is directly applicable. The cookie-based tracking of unique visitors constitutes processing of personal data (online identifiers). Some national data protection authorities may offer exemptions for audience measurement tools, but Gemius's cross-site measurement typically exceeds the scope of such exemptions.
