_hjSessionTooLarge
Causes Hotjar to stop collecting data if a session becomes too large. This is determined automatically by a signal from the WebSocket server if the session size exceeds the limit.
session
_hjSessionRejected
If present, this cookie will be set to 1 for the duration of a user’s session, if Hotjar rejected the session from connecting to our WebSocket due to server overload. This cookie is only applied in extremely rare situations to prevent severe performance issues.
session
_hjSessionResumed
A cookie that is set when a session/recording is reconnected to Hotjar servers after a break in connection.
session
_hjSessionStorageTest
This cookie checks if the Hotjar Tracking Code can use Session Storage. If it can, a value of 1 is set.
Session
_hjTLDTest
When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed.
session
_hjCookieTest
This cookie checks to see if the Hotjar Tracking Code can use cookies. If it can, a value of 1 is set.
Session
_hjLocalStorageTest
This cookie is used to check if the Hotjar Tracking Script can use local storage. If it can, a value of 1 is set in this cookie. The data stored in _hjLocalStorageTest has no expiration time, but it is deleted immediately after creating it so the expected storage time is under 100ms.
under 100ms
_hjSession_
A cookie that holds the current session data. This ensures that subsequent requests within the session window will be attributed to the same Hotjar session.
30 minutes
_hjSessionUser_
Hotjar cookie that is set when a user first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behaviour in subsequent visits to the same site will be attributed to the same user ID.
