The device is available for $99.99, with six months of Halo membership included. It was previously available for $65 on an invitation-only basis under an early access program.

Amazon addresses privacy concerns . “We’ve built strict protection mechanisms for customers’ most sensitive data, like Body and Tone, by storing it locally on the customer’s phone by default, when possible, and deleting it after it’s processed,” it reads, in part. “In doing so, we ensure that Tone speech samples are never accessed and body scan images are only viewed by the customer—we do not use either dataset for improving our machine learning algorithms.”
In a statement, Amazon notes that Body and Tone are both optional features, not required to use the product. The company says it’s reviewing Klobuchar’s letter and is in touch with her office to address any questions.
Among other safeguards, Halo users are required to establish a unique profile separate from their Amazon account, to avoid access by others in the same household.

The associated membership enables many of the signature features of the Halo service for $3.99/month. Amazon says the device and app will continue to track basic metrics of sleep time, heart rate and steps if someone decides not to renew after the six-month membership included with purchase.
