FREQUENTLY ASKED QUESTIONS

1. What are the differences between Nova Smart Rings?

Here's a quick comparison of the main Nova Smart Ring models and their key differences to help you choose the right one:
- Nova R (Brushed Silver): Durable titanium body, perfect for all-around health tracking.
- Nova Crystal (Transparent Sapphire): Stylish, scratch-resistant sapphire glass (more fragile than titanium models).
- Nova X (Brushed Silver): Features a built-in miro OLED display for time and real-time health data (heart rate, steps, calories).
- Nova Pay (Black): Supports secure contactless payments (VISA/MasterCard certified), with full health tracking included.

All models share the same powerful health features — sleep tracking, HRV, SpO₂, stress monitoring, 128 sport modes, menstrual cycle tracking, and more.

2. How can I track my order?

Once your order has shipped, you'll receive a confirmation email containing a tracking link and tracking number. Simply click the link to track your order in real time and stay updated on its delivery status.

3. Is the Nova Smart Ring waterproof?

Absolutely! With a 5 ATM waterproof rating, Nova can withstand pressures equivalent to a depth of 50 meters. That means Nova Smart Rings are perfectly safe for swimming, showering, and everyday water exposure. However, to protect your ring and extend its lifespan, we recommend: Avoiding long exposure to hot water (like hot tubs or saunas), as extreme temperatures may affect the internal sensors.

4. How does Nova protect my privacy and data?

Nova Smart Ring keeps all your data on your phone — never on our servers. There's no cloud storage, and no subscriptions. Your health and fitness information stays private, secure, and entirely under your control. Because we believe your data should belong to you, and only you.

5. Are the Nova Smart Ring and charger safe?

Yes. Both the Nova Smart Ring and its magnetic charger have passed rigorous safety and quality testing. The charger is CE-certified, ensuring it meets European health, safety, and environmental protection standards. The device also complies with FCC Part 15 regulations, confirming it poses no harmful interference and meets RF exposure safety requirements for portable use. Nova is committed to delivering products that are safe, reliable, and comfortable for everyday wear.
