Hotjar does its best to collect data from all the visitors coming to your site. There are, however, several instances where Hotjar will not collect data from your visitor sessions on your site. Hotjar cannot capture visitors who:
- Are excluded from the sample by Hotjar. Learn more about Sampling.
- Don't use one of the supported browsers.
- Have JavaScript disabled.
- Have disabled Hotjar from our Opt-Out page.
- Have cookies disabled. See what cookies are stored by Hotjar.
- Use Private Browser or Incognito mode in some browsers, such as Firefox and Safari - or when localStorage and sessionStorage are not available.
- Run browser plugins such as Ghostery, Unlock or Adblock which explicitly excludes them from loading tracking scripts such as ours.
- Have DO NOT TRACK enabled in their browser.
- Have no trackable usage on your site. Recordings are insightful because they allow you to see what visitors do when they visit your site. If the visitor doesn't do anything and leave the site immediately, this would just clutter the Recordings list with unhelpful data.
- Have their IP blocked within your Hotjar settings.
- Live in a country, like the UAE, where the government blocks the use of Hotjar.
