Frequently Asked Questions

The Pulsyn Rune 1 is a privacy-first smart ring that tracks your health metrics — heart rate, HRV, blood oxygen, sleep, activity, and skin temperature — all while keeping your data entirely on your device. It weighs just 2.4–4g depending on size, is 5ATM water resistant, and lasts up to 7 days on a single charge (up to 60 days with the charging case).

The Rune 1 monitors heart rate, heart rate variability (HRV), blood oxygen saturation (SpO2), skin temperature, sleep stages and quality, steps and activity, stress levels, and recovery scores. All data is processed on-device by an AI health assistant.

The Rune 1 lasts up to 7 days on a single charge with normal use. The included charging case extends total battery life to approximately 60 days between case charges, so you can travel without a charger for weeks.

Yes, the Rune 1 has a 5ATM water resistance rating. You can wear it while swimming, showering, or in the rain. We recommend removing it for scuba diving or high-pressure water activities.

The Rune 1 weighs between 2.4g and 4g depending on ring size — lighter than most smart rings on the market. Most people forget they're wearing it within a day.

Your health data never leaves your device. The Rune 1 processes all biometric data locally using on-device AI. We architecturally cannot access your health data — it's not a policy, it's a technical design decision. Even if we were compelled to hand over data, we simply don't have it.

By default, no. All health data stays on your phone. If you opt into the Pro tier ($5/month), cloud features use end-to-end encryption — your data is encrypted on your device before transmission, and only you hold the decryption keys. We cannot read your data even in transit.

The free-tier AI runs entirely on your device using Gemma, a lightweight open model. It provides health insights, sleep analysis, and activity recommendations without any internet connection. The Pro tier adds more advanced cloud AI capabilities, but all data is end-to-end encrypted.

No. We don't sell, rent, or share your personal or health data with anyone. Our business model is selling hardware and an optional subscription — not your data. Read our full Privacy Policy for details.
