Number Duel
Privacy
Number Duel collects only the information needed to provide core gameplay: a guest nickname, local match history, friend room state, and daily challenge results.
Your guest nickname and recent match history are stored in your browser. Friend room data and daily results may be processed by the game service so matches can stay synchronized, leaderboards can work, and basic issues can be diagnosed.
Number Duel does not sell personal data. The current version does not include advertising trackers, paid accounts, or third-party behavioral advertising.
If you have a privacy question or want to request review or deletion of data associated with a report, contact mars.love.free@gmail.com.
