Playing as a guest
You do not need to give us an email address or create an account to play. Your browser keeps the current round in session storage so you can resume after refreshing. Saved browser rounds expire after 23 hours; signed game sessions expire within 24 hours. When persistence is connected, server records also retain round state and validated selections to prevent duplicate results and calculate community rarity. Copying a result writes it to your clipboard; it does not post it for you.
Optional accounts and public profiles
If registration is enabled, Supabase processes your email address, authentication credentials and session information to sign you in. Google or Apple sign-in is available only when that provider is configured. Authentication uses cookies to keep your session active. Account results, progression, XP and Receipts are stored server-side. Your public username, display name, level, game statistics and leaderboard results can be viewed by other visitors. Your email address and Receipt balance are not included in public profiles. Do not put sensitive personal information in your display name.
Technical information
The hosting service may process IP addresses, request timestamps, browser information and errors to deliver and secure the site. No external analytics provider is enabled by default. Gameplay events are available within the page for future integration.
Advertising and support
Advertising is disabled unless a provider is configured. If Google advertising is enabled, Google may process device information and use cookies under its own policies. See how Google uses information from partner sites. External support or checkout links, when available, take you to that provider. Yuno Ball does not collect card details.
Your choices
You can play without an account, clear browser site data and choose whether to follow external links. Clearing browser data can sign you out and remove your local round; it does not delete server-side records. Contact us with questions about account data. Do not create an account or send personal information if you are under 13.
Privacy questions
See our contact page for the currently available contact options. We will update this policy as features and data practices change.
