Privacy Policy

Last updated: June 30, 2026

1. Information handled by Champ Guess

Depending on how you use the site, Champ Guess may handle:

• Room invite codes, room state, game status, guesses, and player status.
• Usernames you enter for multiplayer rooms.
• Chat messages you send inside a room.
• Local browser data, such as room session tokens, streamer mode, and local leaderboard information.
• Technical data such as browser type, device information, performance metrics, page URL, error details, and approximate request information.
• Advertising and consent signals when advertising is enabled.

2. Information you provide

Multiplayer rooms require a username. Room chat stores messages so other players in the same room can read them. Do not include private personal information in usernames, room chat, or game messages.

3. Local storage

Champ Guess uses browser local storage to remember room session tokens, streamer mode, and local leaderboard information. Local storage stays on your device unless your browser clears it or you clear it manually. Clearing browser site data may remove saved room access and local leaderboard entries.

4. Cookies, advertising, and consent

Google AdSense may be used to serve and measure ads. Google and its advertising partners may use cookies, device identifiers, or similar technologies to serve ads, limit repeated ads, detect fraud, measure ad performance, and personalize ads depending on your region, browser settings, and consent choices.

Champ Guess delays loading the AdSense script until gameplay has started or a game has ended. The site does not intentionally load AdSense while streamer mode is already active. If streamer mode is enabled after ad scripts have already loaded in the same browser tab, the site attempts to pause additional ad requests where supported.

Before advertising consent is collected, Google ad storage, ad user data, ad personalization, and analytics storage default to denied. If a certified consent management platform is added later, you may be shown a consent message where required by law.

You can learn how Google uses information from sites and apps at Google's partner sites policy. You can manage Google ad personalization at Google Ad Settings.

5. Analytics and performance measurement

Champ Guess may use Vercel Web Analytics and Vercel Speed Insights to understand aggregate page traffic and performance. These tools help identify slow pages, device-level performance issues, and deployment quality. Analytics events are configured not to include room codes, usernames, chat messages, or chosen champions as event properties.

6. Error monitoring

Champ Guess may use Sentry to detect crashes and browser errors. Error reports may include technical details such as browser information, stack traces, page path, release version, and timing data. Champ Guess configures Sentry to avoid sending users, cookies, request headers, room query strings, chat messages, room codes, and chosen champions where the application controls the data.

7. How information is used

Information is used to:

• Create, join, and maintain multiplayer rooms.
• Show room players the same board and current game state.
• Deliver chat messages to players in the same room.
• Prevent abuse, spam, and excessive requests.
• Fix errors, improve performance, and monitor service health.
• Serve, limit, measure, and improve advertising when ads are enabled.

8. Third-party services

Champ Guess may rely on these service providers:

• Supabase, for room storage, chat storage, database operations, and Edge Functions.
• Vercel, for hosting, deployments, web analytics, and speed insights.
• Sentry, for error monitoring when configured.
• Google AdSense, for advertising when enabled.
• Riot Games Data Dragon assets, for League of Legends champion icon assets.

9. Data retention

Room data, chat messages, and rate-limit records are kept only as long as needed to run the game, troubleshoot service issues, prevent abuse, or meet operational requirements. Inactive rooms and stale rate-limit data may be deleted automatically. Browser local storage remains on your device until cleared by you or your browser.

10. Your choices

• You can avoid entering personal information in usernames and chat.
• You can clear local storage or site data in your browser settings.
• You can use browser controls to block or delete cookies.
• You can manage Google ad personalization through Google Ad Settings.
• You can enable streamer mode to conceal your chosen champion and avoid intentional ad loading while the mode is active.

11. Privacy rights

Depending on where you live, you may have rights to request access, correction, deletion, portability, restriction, objection, or withdrawal of consent for certain personal information. You may also have the right to opt out of certain targeted advertising or sharing activities. To make a privacy request, use the contact information below.

12. Children

Champ Guess is not directed to children under 13. If you believe a child provided personal information through the site, use the contact information below to request deletion.

13. Security

Champ Guess uses HTTPS, security headers, restricted API origins, rate limits, and service-provider security controls. No website or internet transmission can be guaranteed to be completely secure.

14. International transfers

Champ Guess and its service providers may process information in the United States or other countries where hosting, analytics, monitoring, database, or advertising providers operate.

15. Fan project notice

Champ Guess was created under Riot Games' Legal Jibber Jabber policy using assets owned by Riot Games. Riot Games does not endorse or sponsor this project.

16. Changes to this policy

This policy may be updated when the site changes or when legal, operational, advertising, analytics, or monitoring requirements change. The updated date at the top of this page shows when the policy was last changed.
