Here’s a short video about the privacy features and controls built into Halo.
If you’re a fan of best-in-class privacy and security features, good news—so are we! As Amazon’s health and wellness membership, Halo is designed with customer trust as a foundational tenet. The Halo Band, app, and service are built with multiple layers of privacy and security features to keep your data safe and in your control. We go into detail (lots of detail) below, but here is a quick summary:
Want to dig even deeper? Here are some Frequently Asked Questions (and even better, answers!):
1. What is Halo?
Halo is Amazon’s health and wellness membership. Your membership includes a wrist-worn band that works with the Halo app to provide you with useful data, insights, and services that help you improve your long-term health and well-being.
2. What are the key features included with Halo?
Halo was designed to track more facets of health and wellness than you can shake a carrot stick at:
3. What type of data can Halo collect?
The Halo app can collect information relating to your fitness metrics, body fat composition, demographic data, sleep, and tone of voice. The Halo Band can also measure things like skin temperature, motion, and heart rate to provide you with insights into your health. We believe that the more you understand your health, the more you can improve it. In addition, Halo collects engagement data (data relating to the way you use the band and app). This includes information such as whether you’ve put the band on your wrist, or plugged it into a charger. It also includes things like how often you open or access particular pages within the app, or whether you’ve used a particular feature or started a lab. This helps us improve the Halo service to provide features and content that are most useful for customers.
4. What privacy settings are available in the Halo app?
When it comes to your Halo health data, we’re committed not only to being transparent with you about how we collect and use it, but also to putting you in control of it.
By visiting Settings > Health data in the app, you can download or delete your Halo health data, which consists of the following data: your fitness metrics, heart rate, sleep data, body scan images, 3D body models, body fat percentage, measurements, and weight, as well as your lab results, Tone descriptors, highlights, and trends, and demographic information.
From the Settings page, you can also choose to delete only specific types of Halo health data, such as your Body or Tone data.
Still with us? Excellent. Now let’s check out some of the protections specific to Halo features:
5. Can someone listen to my Tone speech samples?
No. Your recordings from Tone speech samples only exist on your band or smartphone temporarily before being processed on your phone and automatically deleted. They never get sent to the cloud, and can’t even be played back or downloaded, so no one ever hears them.
6. How does Tone work exactly?
Tone analyzes qualities of your voice to help you understand how you may sound to others. By default, Tone is not enabled on your band—it’s an opt-in feature that requires you to set up a voice profile to use it. The voice profile trains Tone to analyze only your voice. Once it’s set up, Tone processes temporary recordings of samples of your speech. Then it analyzes how you may be perceived by others, and displays a summary of the analysis in the Halo app.
You can use Tone in three ways: in its default mode (the way that Tone naturally works once you set it up), by “bookmarking” speech, or by receiving real-time feedback using your smartphone:
If you use Tone in its default mode or bookmark your Tone sessions, the band captures temporary recordings and sends them to the app for Tone analysis. You can mute the mics on your band at any time by pressing the button on your band for about three seconds.
7. How do I know when Tone is recording my voice?
If you’ve enabled Tone and are using the feature in its default mode or to bookmark sessions, the LED light on your band will blink blue twice to indicate when Tone has started collecting temporary recordings.The temporary recordings will continue to be collected until you mute, or turn off, Tone’s mics (check out #8 for more details).
If you capture real-time Tone sessions with your phone, you will see your Tone analysis displayed on your phone screen as you speak. You can end the real-time Tone session with your phone at any time by pressing the red “Stop” button at the bottom of the page.
8. Can I mute the mics on my Halo Band?
You bet. If you use Tone in its default mode or to bookmark sessions, the Tone feature uses the mics on your band. To mute these mics, simply press and hold the button on your band for about 3 seconds. The LED light will flash red to indicate the mics are muted.
To turn Tone mics back on, press and hold the band button for another 3 seconds until you see the LED light flash green. Tone will be back in the default mode.
Your band’s mics also mute automatically when you remove the band from your wrist. If you’re unsure whether they are on or off, you can check the status in the Tone Settings in the app.
9. Can I turn the Tone feature off?
Absolutely. Even if you’ve enrolled in Tone, you can turn the feature off at any time, either by muting the mics or by disabling it altogether.
If using Tone in its default mode or to bookmark sessions, you can turn off Tone temporarily by muting the mics (see #8 for more info on that). You can confirm the status of your band’s mics by tapping on Settings in the app. If you capture real-time Tone sessions using your phone, you can stop your session by pressing the red button at the bottom of the Tone page.
To stop using the Tone feature entirely, go to Settings > Profile > Voice ID > Delete Your Voice ID in the app and delete the voice profile you created when you enrolled in Tone. The mics on your band will stay off until you start fresh by re-creating your voice profile and turning them on again.
10. Where are the speech samples captured for Tone analysis stored?
If using Tone in its default mode or to bookmark sessions, your temporary recordings are stored on your band before being transferred to your smartphone for processing.
If your phone and your band are connected, this transfer happens within seconds. If your band and app aren’t connected, up to one hour of Tone recordings are stored temporarily on your band. As soon as you’re back within Bluetooth range of your phone, they’re transferred to your phone for processing. When your temporary recordings are transferred from your band to your phone, they are automatically deleted from your band. The temporary recordings on your phone are also automatically deleted after processing.
If your band and phone do not reconnect within three days, any temporary recordings on your band will be automatically deleted.
If you capture real-time Tone sessions with your phone, Tone temporary recordings are stored on your phone while being processed. After processing, they’re automatically deleted.
Tone temporary recordings are encrypted in transit, including going between your band and the app on your phone. In addition, the recordings are stored securely on your phone, including using available full disc encryption and any other protections provided by your phone’s manufacturer.
So far, so good! Let’s move on to the Body feature:
11. Are my body scan images private?
Yes. No one but you sees your body scan images unless you choose to share them yourself.
12. Wait, back up. What are body scan images?
Your body scan images are what Halo uses to analyze your body fat percentage and help you track your progress over time.
You create a body scan image by taking a series of photos using your smartphone’s camera. It takes less than a minute and the app guides you through the entire process.
Your images are then sent to the cloud where they are processed and turned into a personalized 3D body model. This 3D model is sent back to your phone and displayed in the app, along with your body fat percentage. A slider tool helps you visualize how your body may change as your body fat increases or decreases.
13. Where are my body scan images stored?
Unless you choose to enable cloud backup, each scan image and 3D body model is automatically deleted from the cloud after processing and stored locally in your app and displayed under “Body.”
Opting into cloud backup allows you to easily save your scan images and 3D body models in case you lose or switch phones. Once you opt-in, your scan images and 3D body models will be automatically uploaded and stored securely in the Amazon cloud.
If you decide later that you want to opt-out, just go to Settings. When you opt out, your images and 3D body models will be deleted from the cloud. They’ll remain in the app on your phone unless you manually delete them or uninstall the app.
If you want to save your scan images to your phone’s Camera Roll, open the individual scan image, click the button next to the camera icon, and select “Save images to phone.”
We’re flying now! Let’s keep it going with Discover and data sharing goodness:
DISCOVER AND DATA SHARING
14. Does Amazon share personally identifiable Halo health data with third party content providers?
No, we do not share your personally identifiable Halo health data with third party content providers without your agreement. These content providers receive aggregated, anonymized data about their programs to help improve the content they provide for Halo members using their service.
15. How can I choose to share my personally identifiable Halo health data with third party services?
You can choose to link your Halo account to a third party service via Settings. Before you link, we will surface screens to you in the Halo app where you can review the categories of data that will be shared with the third party and review information from the third party regarding ways they might use your data. Before linking, you should also review the third party’s privacy or data use policies.
You can stop sharing data with a third party at any time by delinking your account directly from the Halo app. You can see a list of the third parties you’ve linked your account to in Settings > Account linking. If you would like to request deletion of data previously shared with a third party, please contact the third party directly.
16. Can I unlink my account after I’ve chosen to share data with a third party?
Yes. If you’ve chosen to link your account with a third party, you can unlink it at any time by accessing Settings in the Halo app. Once you unlink, we will stop sharing new Halo health data with the third party.
We’re in the homestretch! Let’s finish strong:
SECURITY, DOWNLOAD, AND DELETION
17. If I share my Amazon account credentials with others, can they download or delete my Halo health data?
During set-up of your device, you can choose to protect your Halo health data by verifying a One-Time Passcode via your mobile telephone number or email address.
Doing so will help ensure that only you (and not anyone with whom you might have shared your account credentials) can view or download your Halo health data.
If you opt-out of profile verification, your Halo health data may be available to anyone with whom you’ve shared your account credentials.
18. How can I download my Halo health data?
From the Settings page in the app, you can download all of your Halo health data, which consists of the following: your fitness metrics, heart rate, sleep data, body scan images, 3D body models, body fat percentage, measurements, and weight, as well as your lab results, Tone descriptors, highlights, and trends, and demographic information.
19. How can I delete my Halo health data?
From the Settings page in the app, you can delete all of your Halo health data, which consists of the following: your fitness metrics, heart rate, sleep data, body scan images, 3D body models, body fat percentage, measurements, and weight, as well as your lab results, Tone descriptors, highlights, and trends, and demographic information.
From the Settings page, you can also choose to delete only specific types of Halo health data, such as your Body data or Tone data. Body data deletion includes historical data on body fat percentage, scan images, and associated scan image assets. Tone data deletion includes voice profile, perceived tone analyses, and any speech samples currently stored on your smartphone.
20. How is Halo health data secured?
We use rigorous security protocols to secure your Halo health data, including encryption. All Halo health data is encrypted in transit, including going to and from the cloud or between your band and the Halo app on your phone. Halo health data is also encrypted while being stored securely in the Amazon cloud.
In addition, Halo health data is stored securely on your smartphone, including using available full disc encryption and any other protections provided by your phone’s manufacturer.
CONNECT ALEXA TO HALO
21. Can I connect my Halo to Alexa?
Halo customers can opt-in to Connect Alexa to Halo to ask Alexa for their latest Halo health data. If you choose to enable the feature, you can ask Alexa for data like your health summary, activity score, sleep quality, body composition and more. Note that Halo Band is not Alexa-enabled.
To enable this feature, go to your settings in the Halo app and activate the Alexa option (Settings > Data & Privacy > Alexa, and toggle on “Connect Alexa to Halo.“) You can disable this feature at any time in the Settings section of your Halo app. Click here for more information on how to use Alexa and ask Alexa questions.
22. Will Alexa share my Halo health data with anyone who asks for it?
We know that many Alexa-enabled devices are communal. But your Halo health data couldn’t be more personal! For that reason, members of your household with general access to your Voice History won’t be able to view your Halo health data.
You can create a profile PIN to prevent anyone who has access to your shared Alexa devices or Alexa app from being able to query Alexa for your Halo health data. Simply, create the PIN using the settings in the Alexa app (Settings > Your Profile > PIN > Create) and then enable PIN protection for Halo health data through the settings of the Halo app. To use this PIN, you must either already have an Alexa voice profile or create a new voice profile from the Alexa app under their profile settings. Once enabled, this feature will require you to verbally provide a four digit PIN before Alexa will respond to your Halo related questions. If you wish, you can also enable a five minute timer for your PIN from the Halo app settings. Once enabled, you can ask Alexa for as much of your Halo data as you like within a five minute window without having to provide the PIN for each request.
23. Can Alexa perform Tone analysis?
No. This can only be done from the Halo Band and Halo app.
