Server-Side Tracking Lawsuits

Server-side tracking represents a shift in how businesses monitor consumer behavior online as the practice routes user data through company-owned servers before sending information to analytics platforms and advertisers.

This allows organizations to collect behavioral data while circumventing browser privacy features and cookie consent mechanisms that consumers increasingly rely upon.

The technology works by intercepting user interactions on websites and applications, then transmitting that information from backend servers to third-party marketing platforms and advertising networks. Users never see this data transfer occurring, and browser-based privacy tools cannot detect or prevent it.

How Server-Side Tracking Bypasses Consumer Privacy Protections

When you visit a website using server-side tracking infrastructure, your online behavior gets captured server-side before being forwarded to analytics platforms. Because this happens on the business's own servers rather than your device, companies can track user behavior without triggering browser warnings or requiring visible consent mechanisms.

This tracking methodology also allows businesses to collect sensitive personal information.

Lawsuits Targeting Server-Side Tracking Practices

Multiple class action lawsuits filed throughout 2025 and early 2026 challenge server-side tracking as violations of state and federal privacy statutes. These cases allege that companies implementing this technology violate wiretapping laws and data privacy statutes.

Recent litigation targets companies accused of sharing sensitive user data with Meta and Google through server-side integrations. Plaintiffs argue these implementations violate the California Consumer Privacy Act and various other state wiretapping statutes.

One significant case involves allegations that a major telehealth platform transmitted patient health inquiries and appointment details to advertising networks without proper consent. Another lawsuit challenges a financial services company for allegedly sharing user transaction patterns with data brokers through server-side tracking infrastructure.

The California Privacy Rights Act requires businesses to disclose data collection practices and obtain affirmative consent for selling or sharing personal information. Server-side tracking implementations that obscure data sharing relationships may violate these disclosure requirements.

Federal laws including the Video Privacy Protection Act and Health Insurance Portability and Accountability Act also establish strict rules for handling specific categories of sensitive information.

If you believe your personal information was tracked and shared without proper consent through server-side tracking implementations, you may be entitled to compensation.
