Is 艦これウィジェット safe?

Low risk

艦これウィジェット reads request bodies for any site path matching /kcsapi/ and stores parsed Kancolle API fields locally.

The extension registers a web request listener for any URL ending in /kcsapi/, not only Kancolle hosts. When such requests include Kancolle API form fields, the service worker parses values such as deck, mission, repair dock, map, formation, and construction dock IDs and writes related state to local Chrome storage.
