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.

External Services This plugin connects to the following external services. None are contacted until you explicitly opt in (click “Allow & Continue” on the connect screen), with the single exception of the Google Fonts download flow, which only runs when you separately enable the “Localize Google Fonts” toggle on the Optimizations tab. Speed in China API (api.speedinchinaplugin.com) This plugin sends your public site URL to our backend API at https://api.speedinchinaplugin.com/wp-json/speed-in-china-api/v1/speed-test each time you click “Start Speed Test”, which proxies the request to the Globalping network (api.globalping.io) to run real HTTP timings from probes in mainland China. We also perform a once-per-hour reachability health check by GETting https://api.speedinchinaplugin.com/wp-json/; no site data is sent. Speed test results are stored in your WordPress options table only; we do not retain them server-side. Terms of Use Privacy Policy Globalping (api.globalping.io) Our Speed in China API runs your speed test through the Globalping network (operated by jsDelivr). Globalping probes in mainland China receive only your public site URL — no user-identifying data — and return raw timing/HTTP-status data to our API, which forwards it back to your WordPress site. Globalping Terms Globalping Privacy Freemius (api.freemius.com, freemius.com) This plugin uses the Freemius SDK for license activation and opt-in management. When you click “Allow & Continue” on the opt-in screen, Freemius receives your admin email, site URL, WordPress and PHP versions, and the plugin version, in order to issue a license token and (for premium customers) deliver license updates. Nothing is sent before you opt in; clicking “Skip” or “Maybe Later” keeps the plugin in anonymous mode and no Freemius requests are made. Freemius Terms of Service Freemius Privacy Policy Google Fonts (fonts.googleapis.com, fonts.gstatic.com) When you enable Google Fonts localization on the Optimizations tab, this plugin connects to Google’s Fonts API (fonts.googleapis.com and fonts.gstatic.com) to download font stylesheets and font files, which are then stored and served locally from your server. The font family names already present in your site’s HTML are sent to Google as part of the download URL. No personal visitor data is transmitted to Google by this plugin. The toggle is off by default; no Google Fonts request is ever made until you enable it. Google Terms of Service Google Privacy Policy
