Stressed out? Overwhelmed? Neck in knots? Stomach a mess? Garmin's fitness trackers have you covered. They do all the usual fitness tracking stuff like activity, heart rate, sleep monitoring and more. They also track the time interval between each heartbeat and use that to figure out how stressed you are. If you get too stressed, they will vibrate and remind you to take a moment to breath. Deep breath everyone, this sounds like just what we need these days.

Update: In June 2022, after Roe vs Wade was overturned allowing US states to make access to abortion illegal, we took another look at the privacy and security of the Garmin Watch as a device that can track menstrual cycle and reproductive health data. Our updated review is below. Overall, Garmin does a pretty good job of protecting their users privacy and security and has a pretty good history as standing up to law enforcement requests for their users' data.

What could happen if something goes wrong?

When your *Privacy Not Included researcher wanted to get a fitness tracker, Garmin is what she went with. Garmin seems to do one of the best jobs handling the privacy and security of all the personal data fitness trackers collect. They did suffer that very public ransomware attack in 2020. Ransomware attacks suck and it seems no company is safe from them these days.

Garmin says they don’t sell your personal data to anyone. This is great. Garmin also seems to do a good job with what data they do share, which doesn’t seem to be too much. They ask for explicit consent before sharing things like location data for navigation purposes and emails for marketing.

Garmin may share or sell de-identified aggregate data collected by the Garmin Connect app with third parties to do things like make their features better or for research purposes. This doesn’t worry us too much. Although now is a good time to remind you that it’s been found to be pretty easy to de-anonymize some types of data and track down an individual’s patterns, especially with location data. If you’re worried about this, you can opt out of using the Garmin Connect app, you’ll just lose a lot of cool data about your sleep, stress, and menstrual cycles if you do.

Is our researcher happy with her decision to get a Garmin fitness tracker? Yes, she is. Although it does make her a little nervous that she now leaves her phone's Bluetooth on all the time. But hey, knowing that body battery score is really cool!

Update, August 2022 following the overturn of Roe vs Wade protection reproductive health rights in the United States.

Garmin's wearables and the app they use, Garmin Connect, can be used for period and pregnancy tracking. Still, even though Garmin does collect a lot of very personal information, they do a pretty good job with privacy and security. However, if you share your Garmin Connect app data with another third-party such as MyFitnessPal or Strava, all that very personal data you share is not under the privacy policies of those third-parties, which might not be as good as Garmin's policies. So be very careful who you share your Garmin data with. Better yet, don't share it with anyone. And remember to password protect and lock down your phone so people can't access your period or pregnancy data there either.

When it comes to sharing data with law enforcement, Garmin's privacy policy says, "We may process and disclose personal data about you to others: … to comply with legal obligations, such as a valid subpoena, court or judicial order, or other valid legal process." Which isn't as strong and clear a statement of sharing data with law enforcement as we like to see. We much prefer when companies state they won't give up user data to law enforcement unless required to under subpoena, and even then, we like to see them commit to only giving up the bare minimum necessary.

Does this privacy researcher still use her Garmin fitness tracker? Yes. Does this privacy researcher use it to track her period? Yes. Is she worried that personal information could leak or be shared in a way she doesn't want. Also, yes. But not worried enough to stop using the device, because Garmin does do a pretty good job with privacy and security. And this privacy researcher understands nothing is perfect and we all have to determine our own risks versus reward. Now, if this privacy researcher lived in a state where abortion had recently been made illegal, she'd probably have a different take on matters. This is the sort of evaluation we all have to do right now, as nothing is 100% safe.

Tips to protect yourself

  • Be very careful who you choose to share your Garmin wellness data with.
  • Adjust your privacy settings in the Garmin Connect app to suit your comfort level.
  • Don't connect your Garmin app to any social networks like Facebook, WeChat, etc.
  • When you no longer use the app, go to "Delete account" in the app menu
  • Turn off precise location sharing!
  • Chose a strong password! You may use a password control tool like 1Password, KeePass etc.
  • 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 (eg on iPhone go to Privacy -> Advertising -> Limit ad tracking) and biggest ad networks (for Google, go to Google account and turn off ad personalization)
