CFRooms operates entirely client-side within your browser and does not collect, store, or transmit your passwords or personal data. The only data processed is the public Codeforces submission data and real-time room communication needed to sync your competition sessions.
Your public Codeforces handle and submission statuses are used solely to populate the room scoreboard and live event feed during active sessions.
CFRooms is open-source. You can inspect the entirety of our codebase to verify that we do not maliciously handle or export your browser or session data.
