External Services

This plugin connects to external services to provide Progressive Web App functionality. The following services are used:

Google Workbox Library

This plugin uses Google’s Workbox library to provide service worker functionality and caching strategies.

  • What it’s used for: Workbox is a JavaScript library that provides service worker functionality, including caching strategies, precaching, and offline support. It’s essential for the PWA features of this plugin.

  • What data is sent and when: When a user visits your website, their browser automatically requests the Workbox library from Google’s servers (storage.googleapis.com). This request includes:

    • The user’s IP address (standard HTTP request)
    • User-Agent string (browser information)
    • Referrer information (your website URL)
    • Standard HTTP headers

    This data is sent automatically by the browser when loading the Workbox library, which happens when the service worker is registered on the user’s device.

  • Service provider: Google LLC

    • Terms of Service: https://policies.google.com/terms
    • Privacy Policy: https://policies.google.com/privacy
    • Workbox Documentation: https://developers.google.com/web/tools/workbox

Note: The Workbox library is loaded directly from Google’s servers. No personal data from your WordPress site is transmitted to Google. Only standard HTTP request data (IP address, browser information) is sent, which is standard for any web resource request.

Google Fonts (Optional)

If your website uses Google Fonts, the plugin’s service worker may cache these resources. This is an optional feature that only applies if you have Google Fonts on your site.

  • What it’s used for: Caching Google Fonts resources (fonts.googleapis.com and fonts.gstatic.com) for offline access and improved performance.

  • What data is sent and when: If your site uses Google Fonts, standard HTTP requests are made to Google’s servers when fonts are loaded. This includes IP address and browser information, as with any web resource.

  • Service provider: Google LLC

    • Terms of Service: https://policies.google.com/terms
    • Privacy Policy: https://policies.google.com/privacy
    • Google Fonts Privacy: https://developers.google.com/fonts/faq#what_does_using_the_google_fonts_api_mean_for_the_privacy_of_my_users

Note: Google Fonts caching is only enabled if your website already uses Google Fonts. The plugin does not add Google Fonts to your site; it only caches them if they’re already present.

Privacy Policy

This plugin does not collect, store, or transmit any personal data from your WordPress installation. All configuration data remains on your WordPress server.

However, when users visit your website, their browsers will automatically connect to Google’s servers to load the Workbox library. This is a standard web resource request and follows Google’s privacy policy. No data from your WordPress database or user accounts is transmitted to external services.
