Redfin class action overview:
- Who: Plaintiff Biljana Gallardo filed a class action lawsuit against Redfin Corp.
- Why: Gallardo alleges Redfin secretly shared users’ video-viewing history and mortgage application data with Meta and TikTok.
- Where: The Redfin class action was filed in California federal court.
A new class action lawsuit accuses Redfin Corp. of secretly transmitting users’ private video-viewing activity and sensitive financial information to Meta and TikTok without their consent.
Plaintiff Biljana Gallardo claims Redfin embedded invisible tracking code on its website to intercept and redirect this data to the social media companies.
“Unbeknownst to the plaintiff and the millions of consumers who use the website, Redfin has embedded invisible tracking code known as the ‘Meta Pixel’ and the ‘TikTok Pixel’ on the website,” the Redfin class action lawsuit alleges.
The complaint alleges that each time a user clicks the “Video” button on a property listing, the Meta pixel transmits a tracking event to Facebook containing the user’s unencrypted Facebook ID, the property listing URL and a hashed phone number.
The TikTok pixel simultaneously sends a separate event to TikTok containing the property URL, along with hashed versions of the user’s phone number and email address.
Gallardo argues Redfin acted knowingly because it deliberately installed both pixels, activated “Advanced Matching” — a feature that scans form fields for personal data — and entered into commercial relationships with Meta and TikTok built on these very disclosures.
She contends neither she nor any class member was ever presented a standalone consent form authorizing Redfin to share their video-viewing history or survey responses with any third party.
Redfin class action: pixels let anyone identify users by name from home-search data
The class action lawsuit further alleges that users’ unencrypted Facebook IDs were transmitted as part of every video-viewing event. Unlike hashed identifiers, an unencrypted Facebook ID allows any ordinary person — not just Meta — to identify a Redfin user by name simply by entering the value into a web browser, according to the complaint.
The lawsuit also claims Redfin’s mortgage pre-qualification survey transmitted users’ credit score ranges, home purchase timelines and property preferences to both platforms in real time — data Congress has specifically classified as “nonpublic personal information” under federal privacy law.
The Redfin class action lawsuit contends this enabled Meta and TikTok to target Redfin’s own consumers with advertising based on their home-search activity and financial profiles.
The plaintiff demands a jury trial and requests declaratory and injunctive relief and an award of statutory and punitive damages for herself and all class members.
In other concerns about data privacy, footwear and clothing company Zappos is accused of secretly allowing Meta to eavesdrop on customers’ online shopping activity using embedded tracking technologies.
