I am not an Hotjar expert, but looking right now at the source code of your hotjar.js file it doesn't seem to be per installation but rather one config for all running NocoDBs.

This sections in particular are quite concerning to me:

  window.hjSiteSettings = window.hjSiteSettings || {
    site_id: 2297736,
    r: 1.0,
    rec_value: 0.01,
    state_change_listen_mode: "manual",
    record: true,
    continuous_capture_enabled: false,
    recording_capture_keystrokes: true,
    anonymize_digits: true,
    anonymize_emails: true,
    suppress_all: false,
    suppress_text: false,
    suppress_location: false,
    user_attributes_enabled: false,
    legal_name: null,

    deferred_page_contents: [

  // all the other code

  window.hjBootstrap(
    "https://script.hotjar.com/",
    "modules.5a9f57d95ecbb1bf1965.js",
    "2297736"
  ),
  (window.hjLazyModules = window.hjLazyModules || {
    FORM_SELECTOR: { js: "form-selector.392b5f4f766aeb35682b.js" },
    SURVEY_V2: { js: "survey-v2.7218c468a82710c2c26b.js" },
    SURVEY_BOOTSTRAPPER: {
      js: "survey-bootstrapper.f41ed221e5747a5a4a7b.js",
    },
    SURVEY_ISOLATED: { js: "survey-isolated.8af10abbd1a5f80490de.js" },
    HEATMAP_SCREENSHOTTER: {
      js: "heatmap-screenshotter.e571353a90a331625bf1.js",
    },
    HEATMAP_VIEWER: { js: "heatmap-viewer.2fb5d2a22502dfdfdac6.js" },
    SURVEY_INVITATION: { js: "survey-invitation.1ae4ed40ba57f9c20afc.js" },
    NOTIFICATION: { js: "notification.5e4044e77b0558775cb4.js" },
    INCOMING_FEEDBACK: { js: "incoming-feedback.2856389193450b0481d4.js" },
    PREACT_INCOMING_FEEDBACK: {
      js: "preact-incoming-feedback.80672cee08360a8c286c.js",
    },
    SENTRY: { js: "sentry.f1958c523a41d4a73968.js" },
  });

It seems to load additional js files like --> https://script.hotjar.com/heatmap-screenshotter.e571353a90a3...

Hotjar website has following thing to say:

  > Hotjar should capture the majority of user sessions in Heatmaps and Recordings. We cannot guarantee that a specific user will be tracked.

see: https://help.hotjar.com/hc/en-us/articles/115011624047-Does-...

Can't say if it would have sent data to your hotjar account or not since it was blocked in my browser, but to me this all seems like an involuntary data collection. But again, I am no Hotjar expert. Maybe someone else can chip in here.
