GDPR Statement

LiteSpeed Technologies values your users’ privacy. Although our software does not directly collect any personally identifiable information from visitors to your site, LiteSpeed may still be considered a data processor, as user information may be temporarily cached and/or logged, as outlined in this document.


LiteSpeed Web Server, OpenLiteSpeed, LiteSpeed Web ADC, and related software may record IP addresses as a part of normal logging. An access log and an error log may record visitor IP addresses and URL visited. The logs are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. This logging may be turned off through configuration. It is up to individual server administrators to come up with their own schedule for removing such logs from the file system.

Cache Solutions

Our cache plugins potentially store a duplicate copy of every web page on display on your site. The pages are stored locally on the system where LiteSpeed server software is installed and are not transferred to or accessed by LiteSpeed employees in any way, except as necessary in providing routine technical support if you request it. All cache files are temporary, and may easily be purged before their natural expiration, if necessary, via a Purge All command. It is up to individual site administrators to come up with their own cache expiration rules.

LSCache for WordPress

In addition to caching, our WordPress plugin has an Image Optimization feature. When optimization is requested, images are transmitted to a remote LiteSpeed server, processed, and then transmitted back for use on your site. LiteSpeed keeps copies of optimized images for 7 days (in case of network stability issues) and then permanently deletes them.

Similarly, the WordPress plugin has a Reporting feature whereby a site owner can transmit an environment report to our server so that we may better provide technical support.

Neither of these features collects any visitor data. Only server and site data is involved.

Support Services

Sometimes, when you request technical support, LiteSpeed may ask for login credentials to various areas of your site. You may refuse to share such credentials, however refusal may impact LiteSpeed’s ability to provide the requested support services.

Upon completion of a support ticket, LiteSpeed immediately deletes all login credentials you may have shared.

Any user data encountered by LiteSpeed is kept strictly confidential. We never provide your support ticket information to any third party without your explicit consent.
