What do I get if I don’t want to pay a monthly subscription? Will my ring still work?

Yes your ring and Oura app will still work but you won’t get the full range of benefits and in-depth insights and data available to active members.

What if I don't renew?

Non-paying members have access to 3 simple daily scores: Sleep, Readiness, and Activity, as well as our interactive and educational Explore content.

After a style or size we don't have? 

Let us know, and we can order styles and sizes individually as part of our next stock intake. Please be aware that we only receive new Oura stock every six to eight weeks so unstocked rings may take a long time to arrive in clinic. 

Warranty and returns 

Oura rings are covered by a two-year manufacturer's warranty. This warranty covers preexisting defects in materials and failure to operate in expected capacity.

Please be sure you are happy with your size before purchase. We have free sizing kits available so you can be certain you have the right fit.  We are unable to accept change of mind or do size swaps once the rings packaging has been opened.
