Overview

Kissmetrics is a behavioral analytics platform used by enterprise product teams to track user flows, cohort retention, and funnel performance. It ties behavioral events to individual users over time, enabling long-term lifecycle analysis across sessions and devices.

What This Script Does

Kissmetrics loads a JavaScript library that captures page views, custom events, and user properties. It sets a persistent first-party cookie (typically km_ai and km_ni) to maintain user identity across sessions. Events are sent to Kissmetrics' servers with timestamps, user identifiers, and custom properties. The script supports explicit user identification (e.g., after login) to merge anonymous and authenticated activity into a single profile. Additional cookies track referral source and landing page data.

Consent & Compliance

Consent Category: Analytics

Kissmetrics sets persistent cookies that track individual users across sessions for behavioral profiling. This goes beyond anonymous aggregate analytics. Under GDPR and ePrivacy, persistent user-level tracking cookies require consent. CCPA considers this personal information collection requiring disclosure. Note: Kissmetrics was involved in a 2011 FTC case regarding undeletable tracking, which led to industry-wide scrutiny of supercookie techniques.

Should You Block This Without Consent?

Yes. Kissmetrics sets persistent tracking cookies tied to individual user profiles. The user-level behavioral tracking across sessions constitutes personal data processing that requires consent under GDPR/ePrivacy. Block until the user grants analytics consent.

Is Kissmetrics GDPR compliant?

Kissmetrics typically loads analytics trackers, which are not strictly necessary for your site to work. Under the GDPR and the ePrivacy Directive, non-essential cookies and trackers must stay blocked until a visitor gives clear opt-in consent. So Kissmetrics can be fully GDPR compliant, but only if your site holds its scripts until consent is granted and lets visitors decline just as easily. Compliance depends on how your site loads Kissmetrics, not on Kissmetrics itself.
