As part of Oura’s sleep tracking functionality, Oura Ring continuously measures your temperature trend data while you snooze, generating almost 1,500 data points each day. Natural Cycles then uses all of that data to determine an “absolute value,” which is the measurement you’ll see in the Natural Cycles app — and what’s used to calculate your fertility status.
Here’s how to use them together:
If an Oura Member gives explicit consent, Oura will only share sleep data with Natural Cycles, which includes temperature trends, heart rate, sleep length, and sleep stages. The partnership is a one-way integration, and Natural Cycles does not share any sensitive data with Oura.
Both Oura and Natural Cycles take your privacy and data very seriously and you can revoke your consent to share your information at any time.

Yes. The effectiveness of Natural Cycles is supported by clinical evidence, which shows Natural Cycles is 93% effective under typical use. Under perfect use, i.e. if you never have unprotected intercourse on Red Days, Natural Cycles is 98% effective.
Forgetting to measure doesn’t impact how effective Natural Cycles Birth Control is at preventing pregnancy. However, if the app doesn't have enough data due to poor sleep or forgetting to measure, you might get more Red Days (when you’ll need to abstain from sex or use protection).
You don’t have to wait for Natural Cycles to learn your cycle before you can start using it — Natural Cycles is effective from the first day of use.
