Automatically captured data

Bugsnag automatically captures a variety of data to help you debug your errors. You may wish to avoid capturing some types of data, particularly if there are privacy implications for your users.

User information

User information is used to show you which errors are impacting the most users. Set your own user identifiers if you want to be able to find errors affecting individual users.

Information about the device can be useful to identify if an error is only occurring on some devices.
