Ultrahuman Data Breach: 68 Days to Tell Users
Ultrahuman notified customer on 3 June 2026 that an unauthorised third party gained read-only access to an internal analytics system on 27 March. Email addresses were exposed. No passwords, payment data, or wellness data were affected, and the company says it has found no evidence of misuse.
The ring maker took 68 days to inform users. The UK GDPR requires notification to affected individuals without undue delay where a breach is likely to pose a high risk to their rights and freedoms. Whether Ultrahuman assessed this breach as falling below that threshold, and whether it notified the Information Commissioner’s Office within the required 72-hour window, has not been disclosed.
Ultrahuman has a registered UK entity, Ultrahuman Healthcare Ltd, which brings it within the ICO’s direct jurisdiction. The company has not commented on its regulatory obligations to the Information Commissioner regarding this incident.
In its notification, Ultrahuman said it immediately took the affected system offline and revoked all access once the breach was identified. Remediation steps taken to date include tightened access control policies, hardened endpoint security on employee devices, increased audit frequency across internal tooling, and deployment of export-volume anomaly detection. Mohit Kumar, founder and CEO, signed the notification personally.
Customers should be alert to phishing attempts that reference Ultrahuman, their orders, or their personal data. The company will not request passwords or payment details by email or SMS. Questions can be directed to se***********@********an.com.
The breach affects owners of the Ultrahuman Ring Pro and earlier Ring Air hardware. The site has previously covered the Ultrahuman Home air quality monitor and Ultrahuman sleep and glucose research.
