1. What we collect
Account info (email, name; passwords stored only as encrypted hashes); learning progress (completed lessons, XP, review records — local or cloud-synced); learning journeys (the cross-hall paths you join and your step completion states); AI conversations (questions and replies, for providing the feature and quality improvement); membership status after Creem-hosted checkout (we never touch or store card numbers); basic logs (IP, browser type, access behavior — for security and statistics).
