Hi! I'm the developer of AdMop. The reason why you're being ask to login is because app needs access not only to iCloud but also iCloud Drive. This is for downloading new rules, which I publish as files over iCloud Drive. I'm planning to change that mechanism in the next version of AdMop; the current approach was the fastest "quick and dirty" solution to have a working implementation. That said I do want to keep using CloudKit as a backend - which requires iCloud access - so I can use it as a place for users to store their own white lists; something quite a few have asked me for. Anyway thanks all for trying AdMop - thanks to your feedback I'll include a note in the store description in future for why the app needs iCloud access.
