Frequently asked questions.
Measure at the base of the finger you'll wear the ring on, ideally at the end of the day when fingers are slightly larger. The ring should sit snugly without rotating freely. Each product page lists available sizes with a step-by-step fit guide, and exchanges for a different size are free within 30 days.
Up to 7 days on a single charge depending on usage. The included charger tops the ring up fully in about 90 minutes — most people charge once a week while showering.
No. Every insight — sleep, recovery, heart rate, readiness, and activity — is included for life. You buy the ring once, and your data is never behind a paywall.
The companion app supports modern Android phones (Android 10 and newer) with Bluetooth Low Energy. The ring syncs automatically in the background whenever the app is nearby.
Yes — SENOVA is water resistant to 100m. Showers, swimming, workouts, and everyday life are all fine. We recommend removing it for scuba diving or high-impact sports involving heavy equipment.
You have 30 days from delivery to return your ring in its original condition for a full refund, or exchange it for a different size or finish. Start a return by emailing support@niroga.ai with your order number — our team handles the rest.
Every SENOVA includes a 1-year warranty against manufacturing defects — sensors, battery, charging, and structural faults. It doesn't cover cosmetic wear or accidental damage. Claims are handled by Niroga AI, usually within a few business days.
Yes. Your health data belongs to you: we never sell personal data, payments are processed by Stripe so we never see your card, and you can request export or deletion of your data at any time.

If your order hasn't shipped yet, email support@niroga.ai as soon as possible and we'll change or cancel it. Once shipped, you can still use the 30-day return window.
