| Name | Expires | Description |
|---|---|---|
| _hjSessionUser_{site_id} | One year | Set when a user first lands on a page. It's used to persist the Hotjar User ID, unique to that site and to ensure data from subsequent visits to the same site are attributed to the same user ID. |
| _hjClosedSurveyInvites | One year | Set once a user interacts with an External Link Survey invitation modal. It's used to make sure that the survey doesn't reappear if it's already been shown |
| _hjDonePolls | One year | Set once a user completes a survey on the site. It's used to make sure that the survey doesn't reappear if it has already been completed |
| _hjMinimizedPolls | One year | Set once a user minimises a poll on the site. It's used to make sure the poll stays minimised as a user navigates through the site |
| _hjShownFeedbackMessage | One year | Set once a user minimises or completes Incoming Feedback. It's used to make sure Incoming Feedback stays minimised as a user navigates to other pages where it's set to show |
| _hjid | One year | Set when a user first lands on a page with the Hotjar script. It's 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 |
| _hjTLDTest | Session | When the Hotjar script executes, it tries to determine the most generic cookie path it should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, it tries to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed |
| _hjUserAttributesHash | Session | 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 |
| _hjCachedUserAttributes | Session | 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 |
| _hjLocalStorageTest | Under 100 ms | 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 almost immediately after it is created |
| _hjIncludedInPageviewSample | 30 minutes | Set to let Hotjar know whether that visitor is included in the data sampling defined by your site's pageview limit |
| _hjIncludedInSessionSample | 30 minutes | Set to let Hotjar know whether that visitor is included in the data sampling defined by your site's daily session limit |
| _hjAbsoluteSessionInProgress | 30 minutes | This cookie is used to detect the first pageview session of a user. This is a True/False flag set by the cookie |
| _hjFirstSeen | Session | This identifies a new user’s first session. It's used by Recording filters to identify new user sessions. |
| _hjViewportId | Session | This is used to store user viewport details such as size and dimensions. |
| _hjSession_{site_id} | 30 minutes | This holds current session data. It is used to ensure subsequent requests in the session window are attributed to the same session. |
| _hjSessionTooLarge | Session | This causes Hotjar to stop collecting data if a session becomes too large. It is determined automatically by a signal from the WebSocket server if the session size exceeds the limit. |
| _hjSessionRejected | Session | This cookie, if present, set to '1' for the duration of a user's session, when Hotjar has rejected the session from connecting to our WebSocket due to server overload. It is applied in extremely rare situations to prevent severe performance issues. |
| _hjSessionResumed | Session | This is set when a session/recording is reconnected to Hotjar servers after a break in connection. |
| _hjRecordingEnabled | Session | Set when a Recording starts.It is used to read when the Recording module is initialized to see if the user is already in a recording in a particular session. |
| _hjRecordingLastActivity | Session | Set in Session storage as opposed to cookies. It's updated when a user recording starts and when data is sent through the WebSocket (the user performs an action that Hotjar records). |
