Natural Cycles does not share any sensitive data with Oura. The partnership is a one-way integration and Oura will only share sleep data with Natural Cycles (which includes temperature trends, HR, sleep length, and sleep stages) if an Oura user gives explicit consent.
If you give this explicit consent, Natural Cycles will have access to your Oura sleep data, but Oura will not have access to any of your Natural Cycles data.
Natural Cycles has always taken data privacy seriously and has very strict protocols in place to protect your data. We have never — and never will — sell users’ data. We are a regulated medical device that follows GDPR and we also have our own very heavy data security measures in place that include pseudonymization. We have been preparing for a world where Roe v Wade was overturned and will continue to keep your data secure. Protecting users' information has always been a top priority for Natural Cycles and as that sensitive data becomes more sensitive, we’ll continue to make sure your data is safe with us.
