Automatically captured data

The BugSnag SDK 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.

Data	Default value	Preventing collection
User ID	The user’s IP address	To override set user or to prevent collection configure collectUserIp

Device information

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

Data	Default value	Preventing collection
Locale	The locale of the browser	Modify device in a callback
User agent	The user agent of the browser	Modify device in a callback

Request information

Details about the request can be helpful to reproduce errors.

Data	Default value	Preventing collection
Client IP	The IP address	Configure collectUserIp
Request URL	The URL including query parameters	Modify request in a callback

Breadcrumbs

Breadcrumbs are automatically recorded for common actions and can be helpful to reproduce errors.
