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
