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.
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.
- 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 anonymized 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 220.127.116.11, it will be stored as 18.104.22.168. 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 HTML elements. 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. 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 visitor's browser to our systems using HTTPS if the site which is using Hotjar uses HTTPS.
- The protocols and ciphers suite used to encrypt data in transfer is available at the end of this article.
HTTPS / HTTP
If the site running Hotjar uses HTTP and not HTTPS, the data transmitted to our servers will not be encrypted. We always suggest using HTTPS when using Hotjar so the data transferred is always encrypted.
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 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.
This does not apply to Visitor Recordings - this data is currently not backed up.
