Data Safety, Privacy & Security

Your site and visitor data are safe with Hotjar. There are a number of steps we take to ensure you are the only person who can access your site data and that your visitors' privacy is respected.

Data storage

All data Hotjar collects is stored electronically in Ireland, Europe on the Amazon Web Services infrastructure, eu-west-1 datacenter. Our application servers and database servers run inside an Amazon VPC, Virtual Private Cloud. The database containing visitor and usage data is only accessible from the application servers and no outside sources are allowed to connect to the database. Our data retention times are no longer than 365 days.

Visitor privacy

• Site visitors are assigned a unique user identifier, UUID, so that Hotjar can keep track of returning visitors without relying on any personal information, such as the IP address.
• IP addresses of visitors are always suppressed before being stored. We set the last octet of IPv4 addresses, all connections to Hotjar are made via IPv4, to 0 to ensure the full IP address is never written to disk. For example, if a visitor's IP address is 1.2.3.4, it will be stored as 1.2.3.0. The first three octets of the IP address are only used to determine the geographic location of the visitor.
• When collecting data with Recordings, Hotjar automatically suppresses keystroke data on password fields, as well as when we detect a credit card number being entered into an input field. We also offer the ability to manually suppress data on specific input fields or on-page text containing email addresses/numbers. In both cases, the data is suppressed client-side, the visitor’s browser, which means it never reaches our servers.

Data collection and transmission

• Firewalls are in place exposing only the necessary ports through the internet and between different servers. Intrusion protection system (IPS) software is in place as a second layer of security, which will block access as soon as any suspicious login activity is detected.
• Hotjar transmits data from the visitors browser to our system using HTTPS.
• The protocols and ciphers suite used to encrypt data in transfer is available at the end of this article.

Data access and authentication

Only Hotjar engineers which require such access to perform their job efficiently are given access. Different engineers are given different access rights on different system components as well depending on what their job requires. Engineers who do have access, have their own credentials and these are only valid when used from specific IPs. SSH Key-Based authentication is used for server access. 

Data collected through Hotjar is exclusively reserved for use by our users and customers. Hotjar does not make use of the data collected in any form or way unless consent is officially given by an admin of the Hotjar account, clearly outlining what the data will be used for.

Data access and backup

At Hotjar we use Database replication to keep your data safe in the case of system failure. Full database backups are taken every day, stored on Amazon Cloud Storage (AWS S3), and kept for three days as an electronic copy. In case two or more database nodes would fail concurrently we would have to revert to a backup.

Updating your Privacy Policy for use with Hotjar

As a company based in the European Union, our technology and processes adhere to the strictest legal privacy requirements. In fact, we engaged a specialized law firm to assist us with the process of drafting a policy that is suitable for us, as well as for Hotjar users around the world.

While we always recommend you seek legal advice within your territory, we suggest you review the provisions of our Privacy Policy and ensure your own policy mirrors the same principles we have included at https://www.hotjar.com/legal/policies/privacy.
