Frequently asked questions.
Wrap a non-elastic strip of paper or string around the base of the finger you will wear the ring on, mark where it meets, then measure that length flat in millimetres. Match that length to the perimeter column in the chart.
- Measure near the end of the day, when fingers are naturally a little larger.
- Keep the strip snug, not tight. The ring should stay in place without rotating freely.
- If you are between two sizes, choose the larger size for better comfort during sleep and warmer days.
SENOVA PRO lasts 6 to 7 days, SENOVA AIR lasts 5 to 7 days, SENOVA Elite lasts 15 to 21 days, and SENOVA Active lasts 10 to 30 days depending on usage. The included charger fully powers up the device in about 90 minutes.
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 iPhones (iOS 15 and newer) and 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 5m. 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 info@senovaproducts.com with your order number and our team handles the rest.
Every SENOVA includes a 1-year warranty against manufacturing defects: sensors, battery, charging, and structural faults. It does not cover cosmetic wear or accidental damage. Warranty claims are usually reviewed 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.
SENOVA handles delivery, returns, and warranty service. You can track every order from your account.
If your order has not shipped yet, email info@senovaproducts.com as soon as possible and we will change or cancel it. Once shipped, you can still use the 30-day return window.
