- Tether QVAC Health turns phones into private AI health hubs
- All wellness data stays encrypted locally with on device AI analysis
- Tether links QVAC Health to wider health, robotics, and neurotech bets
Tether, the issuer of the world’s largest stablecoin, is executing a hard pivot into the data sovereignty sector. The company announced the launch of QVAC Health on Wednesday, a privacy-centric application designed to break the “trade-off” between advanced AI analytics and personal data security.
The platform is designed to give users control over their fitness, nutrition, and biometric data without relying on commercial servers or data‑harvesting services. Tether claims that QVAC Health keeps all information encrypted and stored locally on users’ devices.

The ‘Anti-Cloud’ Health OS
Unlike Apple Health or Google Fit, which often rely on cloud synchronization, QVAC Health functions as an offline-first operating system.
Tether CEO Paolo Ardoino said the goal is to remove the trade‑off between strong hardware and privacy. The data from sleep trackers, smart rings, step counters, workout apps, and nutrition tools often sits inside closed systems that do not communicate with each other.
As per a blog post, QVAC Health serves as a neutral link between these isolated ecosystems and allows users to combine all their health data into one view.
A Private, AI‑Powered Wellness Hub
According to the blog post, QVAC Health gathers workout logs, medication reminders, biometrics, and nutrition records into a single encrypted dashboard.
The company describes it as an operating system for personal wellness where all information stays under user control. Its interface is built for simple interactions, letting users type or speak entries such as workouts, symptoms, or meals.
The on‑device AI then interprets and organizes the data directly on the user’s timeline. Also, the app includes medication tracking and privacy‑preserving reminders.
Tether added that the system can function fully offline because its AI models are downloaded P2P, enabling strain, recovery, and trend analysis without internet access.
Future updates will add proactive AI guidance, which will offer recommendations based on real‑time data from wearables and manual logs while keeping all information on the device.
QVAC Fabric: AI on the Edge
Tether plans to expand QVAC Health with direct Bluetooth Low Energy connectivity. This will allow the app to read raw sensor data from supported devices without going through cloud APIs.
The company recently released QVAC Fabric LLM, a new framework that allows large language models to run locally on laptops, phones, and consumer GPUs. Tether stated this architecture supports full LLM inference, fine‑tuning, and training on everyday hardware.
Investments in Robotics and Neural Technology
Earlier this month, Tether participated in a €70 million ($81 million) funding round for Generative Bionics, a robotics startup developing humanoid machines designed for dangerous and repetitive industrial tasks.
The startup is backed by more than two decades of research at the Italian Institute of Technology and is preparing for industrial trials and early deployments scheduled for 2026.
Before that investment, Tether also acquired a majority stake in Blackrock Neurotech for $200 million. The company specializes in brain‑computer interface technology and the investment pushed Tether deeper into advanced health and AI systems.
