The 15-page lawsuit says that consumer information is captured through Whoop’s wearable device, which measures and tracks workouts, sleep patterns, blood pressure, stress levels, heart rate and other health metrics and vitals. According to the suit, Whoop has shared this “treasure trove” of personal data without users’ knowledge or consent via a third-party tracker called Segment embedded into the app—in violation of federal and state privacy laws.
Whoop’s fitness tracker, which consumers receive as part of their annual subscription to the app, is designed to be worn “24/7” to monitor a user’s activity and vitals, the case states. The app offers metrics analysis and hosts a library of health-centered educational videos to help guide consumers looking to improve their overall well-being, the complaint describes.
The filing asserts that through its app, Whoop has secretly shared users’ full names, email addresses, heights, weights, birthdays, genders, cities, usernames and mobile device details. In addition, the app discloses consumer vitals, details about their overall health and the titles of any videos they viewed or requested, the Whoop lawsuit contends.
The alleged conduct flies in the face of Whoop’s “Privacy Principles,” which pledge to keep user data anonymized and protected, the suit charges. According to the case, Whoop has also violated California law by sharing users’ medical information and the federal Video Privacy Protection Act by disclosing their video-watching history without consent.
The class action lawsuit looks to represent all United States residents who watched a video in the Whoop mobile app within the last two years, and all California residents who purchased a Whoop membership.
