Service Worker Storage
If you enable the Keryx app (PWA), a service worker stores cached page content in your browser's Cache Storage to enable offline reading of bookmarked articles. This cache is managed locally on your device and contains only public page content. You can clear it via your browser's developer tools or by unregistering the service worker.
