The LogRocket SDK uses first-party cookies to properly stitch together sessions. These cookies are not visible to our backend, and are only accessible by the clientside SDK while a session is being recorded.
The LogRocket SDK creates cookies with the following prefixes:
_lr_uf_is assigned a random UUID, which is persisted as part of the session data in order to support certain functionality on self-hosted deployments of LogRocket.
_lr_tabs_is used for session persistence, containing unidentifiable information about the current session. In conjunction with the _lr_hb_ cookie, this cookie detects if a LogRocket session with the same appID is active in another tab, preventing multiple tabs from spawning multiple sessions. This cookie also holds Conditional Recording rules, telling the SDK what conditions to look for when triggering sessions.
_lr_hb_is used for cross-tab activity checking and contains a single timestamp that is periodically updated.
These cookies do not contain any identifiable information. They do not record user's IP address or device ID or other identifiable information. These cookies are necessary for LogRocket's basic functionality, and cannot be disabled.
