Privacy Policy

Your privacy is fundamentally important to us at Vanish XO. This Privacy Policy outlines what information we collect, how it is used, how cookies and local storage function, and our advertising practices in compliance with Google AdSense guidelines.

1. Information We Collect

Vanish XO does not require users to create traditional accounts with sensitive personal data to play the core game. The information collected is minimal, non-sensitive, and designed solely to maintain game state and competitive features:

  • Anonymous User Identifier: A randomly generated string (e.g. p_xxxxxxxx) stored locally in your browser to distinguish players and manage multiplayer rooms.
  • Display Name: A chosen nickname or randomly assigned guest name (such as NeonFox42) displayed during matches and on the global leaderboard.
  • Game Results & Leaderboard Data: Records of game outcomes (wins, losses, draws, moves played, and calculated Elo ratings) submitted to track global standings.

Google Sign-In: We offer optional authentication via Google Sign-In (using Auth.js) to enable persistent player profiles and ranked global leaderboard participation. When you sign in with Google, we store only what is needed: a stable user ID, display name, and email address. Your email is never displayed publicly or shared with third parties. No passwords are ever requested or stored.

2. Cookies and Local Storage

Vanish XO utilizes modern browser localStorage to store client preferences such as audio toggles, sound effects state, cached achievements, tutorial view status, and your anonymous player ID.

Cookies are small text files placed on your device to ensure website functionality, maintain secure sessions, and assist our analytics and third-party advertising partners in delivering tailored services.

3. Third-Party Advertising & Google AdSense

  • Third-party vendors, including Google, use cookies (such as the DoubleClick cookie) to serve ads based on a user's prior visits to this website or other websites on the internet.
  • Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visits to our site and/or other sites on the Internet.
  • Users may opt out of personalized advertising by visiting Google Ads Settings .
  • Alternatively, users can opt out of third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info .

4. Analytics Services

We may utilize privacy-friendly analytics tools (such as Vercel Web Analytics) to collect aggregated, non-personally identifiable diagnostic metrics. This data helps us monitor application health, optimize matchmaking speeds, identify browser rendering bugs, and enhance user experience.

5. Children's Privacy (COPPA Compliance)

Vanish XO does not knowingly target, solicit, or collect personal data from children under the age of 13. If you believe a child under 13 has provided personal details on our service, please contact us immediately so we can promptly remove such records from our systems.
