Airplane Mode disables all radio transmission from your Oura Ring, including Bluetooth connection between the ring and app. When Airplane Mode is enabled, your ring will continue to collect and store data.

How to Enable Airplane Mode
To enable Airplane Mode, tap the ring 
icon in the upper right-hand corner of the Home 
tab. Then, toggle the slider next to "Ring airplane mode" on. Confirm that you’d like to turn on airplane mode via the pop-up message. When Airplane Mode is turned on, an 
icon will appear in place of the ring icon in the upper right-hand corner of the app's Home tab.
How to Disable Airplane Mode
To disable Airplane Mode, place your ring on its charger and wait a few seconds for the ring and app to connect. If you experience connection issues, simply close and re-open the Oura App.
Keep in mind that if your ring has been in Airplane Mode for more than a few days, it may take longer for your data to sync with the app once reconnecting with Bluetooth.
When to Use Airplane Mode
Consider turning on Airplane Mode if you’d like to eliminate all EMF exposure from the ring. Keep in mind that the Bluetooth signal from your Oura Ring is only active during a small portion of each day (well below 1%).
You may also consider turning on Airplane Mode if you’re traveling to a different time zone for a short stay and don’t want time zone changes to be accounted for by your ring.
Things to Keep in Mind
Note that Airplane Mode only stays on for a maximum of 7 days at a time. This means that if you’d like to keep Airplane Mode on for extended periods of time, you’ll need to re-enable it on a weekly basis. This is because the ring is taken out of Airplane Mode each time it’s placed on your charger. If so desired, you’ll need to re-enable Airplane Mode once the ring is done charging.
Your ring data will be synced with the app only when Airplane Mode is disabled. Because Airplane Mode is automatically disabled each time you place your ring back on its charger, a data sync will be initiated upon re-charging.
