Most Smart Fitness Devices Lack Essential Data Protection, EFF Warns

EFF says most smart fitness devices still lack basic privacy safeguards, especially transparency reports and end-to-end encryption for health data.

Apple was the only company EFF found that fully encrypts Health app data so even Apple cannot read it.

Google and Apple publish transparency reports, while Whoop and Oura have only limited or planned disclosure practices.

The findings raise concerns that sensitive health data could be exposed to company access, law enforcement requests, or breaches.
