Privacy in consumer wearable technologies: a living systematic analysis of data policies across leading manufacturers

Area of Science:

• Health Informatics
• Consumer Technology
• Data Privacy Law

Background:

• Consumer wearable devices collect vast amounts of biometric data.
• This raises critical concerns regarding data privacy, security, and user rights.
• Existing privacy policies require systematic evaluation.

Purpose of the Study:

• To systematically evaluate the privacy policies of 17 leading wearable technology manufacturers.
• To assess adherence to data privacy principles across seven dimensions.
• To identify high-risk areas and manufacturers in wearable device data governance.

Main Methods:

• Developed a novel rubric with 24 criteria across seven privacy dimensions.
• Analyzed privacy policies of 17 major wearable tech companies.
• Assigned risk ratings based on policy comprehensiveness and clarity.

Main Results:

• High risk was frequently found in transparency reporting (76%) and vulnerability disclosure (65%).
• Low risk was common for identity policy (94%) and data access (71%).
• Xiaomi, Wyze, and Huawei exhibited the highest cumulative risk scores; Google, Apple, and Polar ranked lowest.

Conclusions:

• Significant inconsistencies in data governance exist across the wearable technology industry.
• There is a pressing need for enhanced, sector-specific privacy standards for wearable devices.
• Continuous monitoring and accountability are crucial in this evolving domain.
