Ultrahuman's data breach exposes customer details, but passwords stay safe

Oura smart ring competitor Ultrahuman has notified customers about a data breach that compromised their information.

In an email sent out on Wednesday, Ultrahuman founder and CEO Mohit Kumar said that on March 27, an unauthorized party gained access to an internal system that Ultrahuman uses for internal analytics. It involved customer contact and account details, as well as order and transaction history.

Kumar said that the breach did not include passwords or payment data and that the data itself was not corrupted, as the system “did not permit modification or deletion of data.” Ultrahuman said it revoked access to the system and took it offline.

Mohit wrote that Ultrahuman has monitored “public and other internet channels” for any signs of the compromised information and thus far has not found any.

He also detailed steps Ultrahuman has taken to prevent future such incidents. These include strengthening and limiting access to internal systems, stepping up security on employee devices, increasing how often access audits are conducted, and improving system alerts.

Ultrahuman has a FAQ for further info for customers, and has directed any that are concerned to email security-2026@ultrahuman.com.

Ultrahuman returned to the US market in March with the Ultrahuman Ring Pro. It had left the market in 2025 as the result of a patent-infringement lawsuit brought and won by Oura. Aside from the Ring Pro, Ultrahuman has other health-related products like Home, a sleep monitor. Ultrahuman has about 700,000 daily active users in the US.

AP has reached out for further details on how many are affected by this breach and we’ll update the story if we hear back.
