Privacy First. Designed for Everyday Life.
Luna is built with a privacy-first approach. Your health data belongs to you — and always stays that way. Luna is both HIPAA and GDPR compliant, meaning your information is protected under some of the world’s strictest privacy standards.
Because Luna is a fully integrated, end-to-end system, everything — from the ring to the app and analytics — is managed within the Luna ecosystem. This means your data is never shared with third-party partners and is never sold. It is used only to provide your personal health insights through the Luna app.
Lightweight, comfortable, and water-resistant, the Luna Ring is designed to be worn day and night so you can track your health effortlessly — with the confidence that your data remains secure, private, and entirely yours.
