When most people visit a real estate website, they make a silent assumption. Maybe you’re watching a video tour of a two-bedroom in a neighborhood you’ve been eyeing for months while perusing listings. It feels intimate and personal. You don’t really consider the possibility that someone else, like a social media company or an advertiser, might be observing as well. A recent class action lawsuit suggests that this assumption may have been seriously misguided.
Redfin Corporation is accused in a federal lawsuit of directly integrating invisible tracking code, namely the Meta Pixel and TikTok Pixel, into its website. According to the lawsuit, a signal was sent out each time a user clicked the “Video” button on a property listing. to Facebook. To TikTok. transporting information that users never consented to share.
What type of information? The complaint becomes so detailed that it is difficult to ignore. The property listing URL, a hashed phone number, and the user’s unencrypted Facebook ID were purportedly sent by the Meta Pixel. The property URL and hashed versions of the user’s email address and phone number were sent by the TikTok Pixel. The hard-to-overlook detail is that an unencrypted Facebook ID is not the same as a jumbled code. The complaint claims that anyone could enter that value into a browser and see a person’s name, not just Meta’s engineers. There isn’t a technical flaw hidden deep within a server. That is directly on the surface.
Biljana Gallardo, the plaintiff, goes one step further. She contends that this data flow also affected Redfin’s mortgage pre-qualification survey, which is the kind of tool people use when they’re seriously considering a purchase. Property preferences, credit score ranges, and timelines for purchasing a home are all purportedly sent in real time to Meta and TikTok. That type of information has particular protections under federal law. It has been designated as nonpublic personal information by Congress. According to the lawsuit, Redfin sent it anyhow.
Redfin is not the only one doing this. The broader pattern of real estate platforms subtly integrating third-party pixels into their user experience appears to have been developing for some time, and Zillow is the target of a parallel lawsuit with nearly identical accusations. Although the precise extent of the practice’s industry-wide prevalence is still unknown, the Redfin and Zillow cases collectively imply that it wasn’t a singular oversight. According to both lawsuits, the tracking was installed on purpose in order to increase revenue and foster advertising relationships.
The intentionality argument is what gives the Redfin lawsuit a particularly sharp feel. Redfin did not unintentionally leak this information, according to Gallardo’s legal team. It triggered “Advanced Matching,” a feature that actively searches form fields for personal data. It entered into business agreements based on precisely these kinds of disclosures with Meta and TikTok. The lawsuit presents this as a business decision rather than an error.
For anyone who has ever completed a mortgage survey believing it was solely between them and a real estate platform, there is something unsettling about that framing. There is a significant discrepancy between what users thought was occurring and what was purportedly occurring. According to the complaint, users were never presented with a standalone consent form authorizing these disclosures. That is not a small detail for the millions of users of Redfin’s website.
The lawsuit, which was submitted to the U.S. District Court for the Central District of California, asks for both punitive and statutory damages and calls for a jury trial. It’s also important to note that Zappos is the target of a similar lawsuit regarding Meta tracking tools, indicating that the legal scrutiny surrounding embedded pixels is unlikely to end anytime soon.
The courts will have to decide whether Redfin is ultimately subject to substantial liability. However, the lawsuit raises issues that are urgent regardless of the outcome: When you browse listings, what precisely are real estate platforms collecting? With whom are they sharing it? And does a privacy policy’s hidden pixel disclosure actually equate to consent?
