Redfin is facing a proposed class-action lawsuit alleging it secretly shared users' video-viewing activity and financial data with Meta and TikTok through embedded tracking pixels. Plaintiff Biljana Gallardo filed in California federal court. The complaint claims that each time a user clicks “Video” on a property listing, the Meta Pixel sends Facebook the user's unencrypted Facebook ID, the property URL, and a hashed phone number, while the TikTok Pixel sends a separate event with the property URL and hashed phone and email. The suit argues the unencrypted Facebook ID is particularly problematic because anyone can identify a Redfin user by name by entering it into a browser. Gallardo also alleges Redfin's mortgage pre-qualification survey transmitted credit score ranges, home purchase timelines, and property preferences to both platforms in real time, data Congress has classified as “nonpublic personal information.”
