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.

This documentation is for version 7 of the Bugsnag JavaScript notifier. If you are using older versions, we recommend upgrading to the latest release using our Upgrade guide. Documentation for the previous release can be found on our legacy pages.
