Can users clear the service worker cache?

问题:

I've built a Progressive Web App that uses caching, but it's unclear to me whether users can (accidentally or on purpose) clear the service worker cache, which may clear my tracking data.

回答1:

When a user clears their browsing data / cookies, this clears all site storage which includes the SW cache, cookies, local storage, indexeddb, and any other local caching system.

回答2:

Furthermore, Ctrl-F5 forces a cache refresh, and is intended to abandon all cached content including service worker cache and just retrieve all content from the servers again.
