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.

Update: In June 2022, after Roe vs Wade was overturned allowing US states to make access to abortion illegal, we took another look at Oura's privacy and security as a device that can track menstrual cycle and reproductive health data. Our updated review is below. Overall, Oura does a pretty good job of protecting their users privacy and security and clearly states how they will handle potential law enforcement requests for any reproductive health tracking data.

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 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.

Update, August 2022 following the overturn of Roe vs Wade protection reproductive health rights in the United States.
We went back and took a look at Oura's privacy and security policies and how they apply to tracking reproductive health information. Here's what we found.

Oura does say they have period tracking features, such as the ability to track body temperature, respiratory rate, and sleep to help predict your period. Oura is based in Finland and governed by Europe's stricter GDPR health laws, which is good. They outlined their commitment to reproductive health and privacy in a blog post on their site following the Roe vs Wade decision.

When it comes to protecting users' privacy, Oura states they do not share the Oura app data with third party advertisers and they do not share user personal data for any third party’s advertising or marketing purposes.. Which is great. As for how they handle law enforcement request for data, Oura's privacy policy states, "Oura will oppose any request to provide legal authorities with access to user data for surveillance or prosecution purposes, and will notify users if Oura receives any such request." This is good too.

All in all, Oura seems to remain a company with strong privacy and security practices, governed by stricter GDPR privacy laws, with a stated commitment to share a little data with law enforcement as they are able to. This makes us feel pretty good about how Oura approaches reproductive health tracking. A reminder though, nothing is 100% safe online, so password protect those devices with period or pregnancy tracking apps and because of what you chose to share at all times.

Tips to protect yourself

  • Check out Oura Ring's Safety recommendations
  • 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.
  • Be very careful what third party companies you consent to share you health data with. If you do decided to share your health data with another company, read their privacy policy to see how they protect, secure, and share or sell your data.
  • Use your device privacy controls to limit access to your personal information via app (do not give access to your camera, microphone, images and videos)
  • Keep your app regularly updated
  • Limit ad tracking via your device (e.g. on iPhone go to Privacy -> Advertising -> Limit ad tracking) and biggest ad networks (for Google, go to Google account and turn off ad personalization)
