For a CIPA pixel lawsuit, preserve the California user context, consent interface and choice, communication or user action, request timing, script initiator, recipient, payload contents, identifiers, screenshots, and reproduction steps. Tie each transmission to the browser state that produced it.
CIPA contains distinct provisions. Section 631 addresses tapping, unauthorized connections, and learning the contents or meaning of a communication in transit. Section 632 addresses eavesdropping upon or recording a confidential communication without all-party consent. Section 638.51 addresses pen registers and trap-and-trace devices, subject to statutory exceptions.
The browser record does not decide whether a tracker satisfies a statutory definition, whether the communication was confidential, whether a participant or service-provider defense applies, or whether consent was legally sufficient. Counsel applies those questions to the preserved facts and current authority.
