What you can play
NUMO DUEL offers solo and AI practice as well as online math battles. Online competition needs a functioning internet connection and the multiplayer server. Match scores are calculated according to the game engine's rules.
Fair play
Do not automate answers, tamper with game traffic, impersonate other users, abuse opponents or attempt to interfere with the service. Online rankings are calculated from completed real-player matches, not local practice sessions.
Availability
Game availability depends on the hosting server, network connection and device. Offline practice features may work after the app assets have been cached, but online opponents and live rankings require server connectivity.
Account limitations
The current implementation creates an anonymous account in Supabase Auth rather than requiring permanent email login. Removing application storage or reinstalling the app may make earlier online ranking records inaccessible. No cash prizes or real-money betting are offered.
Account deletion
The game offers account deletion from My Account. This removes your login identity, preferences and verified ranking profile. After deletion, historical opponents may retain anonymous match outcomes. Payments are not yet enabled; future paid plans will require separate purchase cancellation and refund terms.

Before public launch
The app owner must supply final legal terms, appropriate contact details, age-related requirements and data rights procedures before making the service public.
