# What the Oura Ring 4 knows about you Made by Oura. 12 findings on record, 12 verified against primary sources. Every line is checked; a maker's claim is labeled as a claim, and we say so when nothing is on record. ## Data retention In 2021 Oura quietly expanded how it uses your data for research alongside the launch of its paid membership, and never directly notified existing users or asked them to agree again. - Posture: Verified - As of: 2021-05-01 - Source: Oura Privacy Policy (current) (https://ouraring.com/privacy-policy) ## Biometric storage Oura stores menstrual cycle data, body temperature, and reproductive health signals. After the 2022 Dobbs ruling, this type of data became a documented legal risk in states with abortion restrictions. Data is stored in Finland under GDPR but is accessible to Oura and subject to US legal process. - Posture: Verified - As of: 2022-06-24 - Source: Oura Cycle Insights feature page (https://ouraring.com/cycle-insights) ## Cloud upload There is no opt-out from cloud sync. The app requires an internet connection and all your biometric readings upload to Oura's cloud. The ring buffers about six weeks of data locally as a backup, but there is no way to keep data on the ring or phone long-term. - Posture: Verified - As of: 2024-01-01 - Source: Oura Support: How does Oura store my data?
