Hotjar is a powerful analytics tool that helps you understand user behavior through heatmaps and session recordings.
_hjSession_
A cookie that holds the current session data. This ensues 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 behavior in subsequent visits to the same site will be attributed to the same user ID.
365 days
_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
hjViewportId
This cookie stores user viewport details such as size and dimensions.
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
_hjUserAttributesHash
User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated.
session
_hjCachedUserAttributes
This cookie stores User Attributes which are sent through the Hotjar Identify API, whenever the user is not in the sample. These attributes will only be saved if the user interacts with a Hotjar Feedback tool.
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.

_hjHasCachedUserAttributes
