No Gambling & No Betting Disclaimer

CupUndo is a 100% free-to-play, simulation-only platform built entirely for fun and entertainment purposes. We do not support, facilitate, promote, or encourage real-money sports betting, gambling, or wagering of any kind. There are no entry fees, no virtual currency purchases, and no real-money prizes or payouts. All predictions, scores, and badges earned on this platform have zero monetary value.

1. Terms of Service

Welcome to CupUndo ("the Service"). By accessing or using our website, you agree to comply with and be bound by these Terms of Service.

A. Eligibility

This platform is open to users worldwide who participate purely for recreational and simulation purposes. By playing, you represent that your use does not violate local regulations regarding free simulation prediction games.

B. Account and Guest Usage

We allow users to create temporary "Guest" accounts to test predictions immediately. Guest session data is kept in your local browser storage. We enforce unique guest nicknames to ensure correct leaderboard calculation. We reserve the right to delete guest records at any time to prevent spam or namespace squatting.

  • Session Indicators: Locally stored tokens used to map prediction votes to your account.
  • IP Addresses: Collected in server logs strictly for rate-limiting, security controls, and anti-spam measures.

B. Third-Party Services

We connect to Google OAuth for users who sign in via Google. We only request basic identification fields (public profile info, name, and email) to link predictions across devices.

C. Data Deletion

You can delete your local guest session instantly by clicking the "Logout Session" button on the Profile tab.

3. Cookie Declaration

Cookies are small files placed on your device. We use them strictly for the following purposes:
