Lawsuits are rapidly multiplying against website operators over how user information is collected and shared. Plaintiffs are increasingly creative in asserting that website tracking tools, especially those tied to search bars, violate wiretap and related electronic communications laws. One emerging legal theory invokes “trap and trace” provisions, meant for surveillance devices, to challenge the capture of search bar data online.
Under federal and many state statutes, “trap and trace” devices refer to tools that capture dialing, routing, addressing, or signaling information—like the numbers someone dials on a telephone—without recording conversation content. Though these laws were written with telephones in mind, their language has been cited in internet privacy cases.
Plaintiffs allege that websites, by using embedded third-party code, session replay scripts, or tracking pixels, collect metadata related to users’ search bar interactions—including queries entered, timing, and user identifiers. They claim that this unauthorized collection and downstream transmission to third parties is functionally equivalent to the operation of a trap and trace device, thus violating wiretap and privacy laws.
Courts have not yet reached consensus on whether the collection of search bar metadata meets the definition of a trap and trace device under existing statutes. Some judges find the analogy strained, while others entertain the possibility, especially where sensitive search queries and user information are in play. As litigation evolves, the boundaries of trap and trace theories in the web context remain unsettled.
Because of this risk, website operators should carefully assess how search bar data is collected, stored, and shared. Transparency in privacy disclosures, clear user consent processes, and regular auditing of third-party scripts and partners are key. Ignoring these steps may lead to costly litigation and regulatory scrutiny.
As plaintiffs test new claims under old wiretap laws, even routine website features like search bars can become legal flashpoints. Website operators are well-advised to monitor legal trends closely and strengthen data privacy safeguards now—before trap and trace claims gain more traction in court.
