Third Party Compatibility The vast majority of plugins and themes are compatible with LSCache. Our API is available for those that are not. Use the API to customize smart purging, customize cache rules, create cache varies, and make WP nonce cacheable, among other things. Privacy This plugin includes some suggested text that you can add to your site’s Privacy Policy via the Guide in the WordPress Privacy settings. For your own information: LiteSpeed Cache for WordPress potentially stores 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. In addition to caching, our WordPress plugin has online features provided by QUIC.cloud for Image Optimization and Page Optimization services. When one of these optimizations is requested, data is transmitted to a remote QUIC.cloud server, processed, and then transmitted back for use on your site. QUIC.cloud keeps copies of that data for up to 7 days and then permanently deletes it. Similarly, the WordPress plugin has a Reporting feature whereby a site owner can transmit an environment report to LiteSpeed so that we may better provide technical support. None of these features collects any visitor data. Only server and site data are involved. QUIC.cloud CDN, if enabled, uses LSCache technology to access your site, and serve your content from remote global nodes. Your data is not accessed by QUIC.cloud employees in any way, except as necessary in providing maintenance or technical support. Please see the QUIC.cloud Privacy Policy for our complete Privacy/GDPR statement.
