Wearable technologies—such as smartwatches and fitness trackers—are now embedded in the daily lives of millions. These devices collect continuous streams of personal data, from heart rate and sleep patterns to geolocation, activity levels, and biometric signals. Yet despite their ubiquity, the privacy implications of wearables remain underexamined by the public.
This video presents findings from a systematic analysis of the privacy policies of 17 major wearable technology companies, including Apple, Fitbit, Garmin, Samsung, Huawei, Whoop, and others. Our research team developed an evaluation framework based on industry best practices to assess how companies manage user data across seven key categories, including:
- Government and third-party data access
- Breach notification protocols
- Vulnerability disclosure programs
- Data retention and user control
Key findings include significant gaps in transparency, inconsistencies in breach response mechanisms, and widespread sharing of user data with third parties. Notably, fewer than half of the companies reviewed had strong breach notification processes in place, and only two—Apple and Google—scored highly across all assessed categories.
As wearable adoption continues to grow, the need for robust data governance, user protections, and regulatory oversight becomes increasingly urgent.
