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:
- Visitors who are excluded from the sample by Hotjar. Learn more about Sampling
- Visitors not using one of the supported browsers
- Visitors with disabled JavaScript
- Visitors that have opted out from our opt-out page
- Visitors with disabled cookies. See what cookies are stored by Hotjar
- Visitors using Private mode in some browsers, such as Firefox and Safari - or when localStorage and sessionStorage are not available
- Visitors who run browser plugins such as Ghostery, unlock or Adblock which explicitly excludes them from loading tracking scripts such as ours
- Visitors that have DO NOT TRACK enabled in their browser
- Hotjar doesn't save Recordings with no tracked usage – Recordings are insightful because they allow you to see what visitors do when they visit your site. If they don't do anything and leave the site immediately, this would just clutter the Recordings list with unhelpful data.
- Visitors have their IP blocked within your Hotjar settings
- Visitors live in country, like UAE, where government blocks the use of Hotjar
