Continuing my seemingly never-ending quest of digging through privacy policies, this time I analyzed how the most popular wearables companies handle their customers’ data. Fitbit, Biostrap, Motiv, Oura and Whoop all are on the cutting edge of health technology, but are their privacy practices on par with that or not?

A fellow biohacker Alex Fergus provided me with the opportunity to publish my little research article on his website. Over the years he has published tons of information on fitness, sleep and – of course – health gadgets. Few days ago he published the most comprehensive red light panel comparison I’ve ever seen, analyzing everything from EMF levels to irradiance and LED flicker. Let’s just say he knows his stuff, so I’m excited to try to match his professionalism on that space with mine about privacy.

I believe it’s time for the biohacker community to start valuing their data more. In my guest blog post you’ll learn:

  • What data do these wearables collect?
  • Are they selling or exchanging data with third parties?
  • Data retention – how long are they storing your data?
  • What can you do?
  • And more…

So head over to and learn everything you need to know about wearables and privacy!
