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 or require paid accounts.
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.
Local Browser Data
Some game preferences and recent results may be stored locally in your browser so the game can remember settings or scores between visits. Clearing your browser storage may remove that local history.
Local browser data is used to make the game feel continuous on the same device. Examples may include a guest nickname, selected language, recent local results, daily quest progress, and reward state. This information is not needed to browse the public guide pages.
Analytics and Service Data
Basic analytics may be used to understand page performance and diagnose reliability problems. The goal is to operate the game, improve loading and gameplay, and respond to support requests without selling personal data.
Friend rooms and daily challenge features may send limited gameplay data to the service so two players can stay synchronized or daily results can be displayed. Support requests sent by email are handled through the email address you use to contact the project.
Data Choices
You can clear local game data by clearing site storage in your browser. For privacy questions, review requests, or deletion questions related to service-side reports, contact mars.love.free@gmail.com.
