# Data Handling

### Session Data

How session data is handled is dependent whether the app is set to use the Senstream cloud or use the local file browser.  For more details about these two methods please refer to the iOS app documentation on:

[Data Storage: Senstream Cloud](/senstream-researcher-ring-application-user-guide/ios-mobile-app/data-storage-senstream-cloud.md)

[Data Storage: Local Files Browser](/senstream-researcher-ring-application-user-guide/ios-mobile-app/data-storage-local-files-browser.md)

### Product Analytics

Anonymous user behavior analytics events are collected by a Senstream-managed server to improve the software’s design and service. Quality of service events are also collected directly from the ring’s firmware to monitor any performance issues in the field.
