Is Userlane safe?

Low risk

Userlane transmits visited URLs and user identifiers to its servers and sends session tokens as metadata to a third-party error tracker.

The extension monitors tab navigation and, for pages matching a configured list, sends the full URL along with a company ID and user ID to Userlane's analytics API. When errors occur, the extension forwards the user's raw session token, managed-storage credentials, and company identifiers as metadata to Sentry, a third-party error tracking service. The extension also writes its presence and internal API handles to the shared window object on every page, which page scripts can read.
