# Ending a recording

![Image: alert icon.](https://cdn.document360.io/c97072d7-dbc3-41f6-b55e-b62dbde0527b/Images/Documentation/Important_icon_LONG(14).png)When using the Portal website to record data with the Flow or DevKit headset, it is strongly recommended that you use a Chrome internet browser. Other browsers are not guaranteed to work.

A recording ends when the maximum duration elapses or the researcher clicks the **Stop Recording** button. All captured data is automatically uploaded to Kernel Cloud for processing and analysis. If you are done recording datasets, there are important steps to follow.

#### To end a recording and remove the headset:

1. If necessary, click the **Stop Recording** button on the Portal Flow UI.  ![](https://cdn.document360.io/c97072d7-dbc3-41f6-b55e-b62dbde0527b/Images/Documentation/image-1724892049348.png)

3. Remove the headset according to [Removing the DevKit from a participant](/v1/docs/removing-the-devkit-from-a-participant) or [Removing the Flow Headset from the participant](/v1/docs/removing-flow2-from-the-participant).

NOTE:Note that if you try to stop the recording before a task event is received that indicates the end of the experiment, you will see a warning at the top of the screen and receive a warning popup. ![](https://cdn.document360.io/c97072d7-dbc3-41f6-b55e-b62dbde0527b/Images/Documentation/image-1724892120612.png)
