Tracking health biometrics has its merits. And wearing a watch 24/7 can be cumbersome. Oura makes a ring that tracks your health stats and aims to help you sleep better and feel better. And it seems the rich and famous--from Prince Harry to the NBA, WNBA, and more--have taken a shine to this little ring. It tracks sleep, steps, calories, as well as heart rate, respiratory rate, temperature, inactive times, and even naps. Oura offers up not one but two privacy policies that cover everything from the device and app to a privacy policy for sharing data with your doctor, trainer, or coach. It's different, and maybe that's a good thing.

What could happen if something goes wrong?

From what we can tell, the Finnish company that makes the Ōura does a pretty good job with the privacy of all the personal data this little ring collects. Ōura says they don’t sell or rent your personal information or share the Ōura app data with third party advertisers. This is great.

This device does track your biometric data closely. So closely, in fact, that there have been academic studies done that show data from the Ōura ring can help predict the start of covid-related symptoms and maybe even pregnancy. It’s a good thing Ōura seems to protect that data carefully. It’d be very weird for a company to know you’re pregnant before you do.

Tips to protect yourself

  • Consider turning on a “Ring airplane mode” feature which allows to proactively disable all radio transmission from the ring, which causes the ring to lose connection to the app, at the moments you do not want your data be collected.

Review: Oura Ring
No, you can’t diagnose yourself for Covid-19 by wearing a ring. But it can tell me when my period is coming.

Researchers say Oura rings can predict COVID-19 symptoms three days early
Christine Fisher
One of the challenges to curbing the spread of COVID-19 is that asymptomatic individuals, or carriers, can spread the virus before they realize they are infected. In April, researchers from West Virginia University’s (WVU) Rockefeller Neuroscience Institute (RNI) and WVU Medicine set out to predict symptoms before they appear using wearable rings by Oura and AI prediction models. Now, the researchers claim their digital platform can detect COVID-19 related symptoms up to three days early with over 90 percent accuracy.

UCSD Launches Study Using Oura To Explore Pregnancy
Although women are the majority of the global population, “women’s health” is still treated as a specialty. Shockingly, even with common events like pregnancy, there is a lack of standards around what to expect for certain elements of your health like “when can you tell if you’re pregnant” or “what should your heart and temperature be doing day by day.”
Is There Privacy with Wearables? Case Oura Ring
Joel Latto
Out of all the information we generate (willingly or unwillingly) out there, nothing gets more personal than health data. Traditionally, health data has been collecting dust in some public healthcare sector’s file cabinet, but thanks to fitness and wellness gadgets and services, that data is now scattered across the world.

Go to a European tech event and you will likely notice at least one attendee sporting a chunky, pewter-coloured band around one of their fingers. This is the Oura ring, a sleep tracker developed by Finland-based startup Oura Health that has become the latest craze in self-improvement wearables.
