Privacy Policy

Last updated: June 24, 2026.

Information We Process

  • - Account information you provide through Supabase Auth, including your email address and profile username.
  • - Profile details you choose to save, such as display name, about me text, friend settings, Discord username, and linked Riot account name.
  • - Riot account information you search for or link, including Riot ID, platform/region, public summoner details, ranked entries, match history, champion mastery, and challenge data returned by Riot APIs.
  • - Game and multiplayer data, including lobby codes, player progress, chat messages, friend requests, direct messages, contact submissions, and local gameplay statistics.
  • - Technical information such as request logs, IP-derived rate limiting data, browser storage used for session recovery, and error diagnostics.

How We Use Information

  • - To provide account lookup, match history, mastery, challenge, quiz, multiplayer, social, and profile features.
  • - To remember recent searches, prevent abuse, debug production issues, enforce rate limits, and improve application reliability.
  • - To store aggregate or app-specific rankings based only on accounts searched through KnowLeague. These rankings are not official League of Legends global rankings.

Riot Games Data

  • - KnowLeague uses Riot Games APIs and public game asset sources to display League of Legends account and match information.
  • - Riot account data is owned and controlled by Riot Games and is subject to Riot Games policies. KnowLeague is not endorsed by Riot Games.
  • - Successful Riot account searches may be stored to power shared search suggestions and internal aggregate metrics.

Storage and Retention

  • - Some preferences, game progress, recent searches, and lobby pointers are stored in browser localStorage. Riot profile lookup responses may be cached in browser sessionStorage until the browser session closes.
  • - Server-side Riot lookup responses may be cached briefly to reduce API calls and rate-limit pressure.
  • - Account, profile, friend, message, lobby, contact, and aggregate metric records may remain in Supabase until deleted or cleaned up through future retention tooling.

Sharing

  • - Public profile information may be visible to other users. Private account fields are intended to remain available only to the owner and server-side features.
  • - We do not sell personal information. Future analytics, ads, or payments will require updated disclosures before launch.
  • - We may disclose information when required for security, abuse prevention, legal compliance, or service operation.

Your Choices

  • - You can clear browser storage from your browser settings.
  • - You can edit your KnowLeague profile from the profile screen.
  • - For alpha deletion, privacy, or support requests, use the in-app contact action or the contact method provided by the site operator.
