Privacy

Stored in your browser

Settings you choose are kept in your browser's local storage and never sent to us:

• theme, background animation and spoiler settings;
• Play: your best score, remembered nickname and quiz mode;
• dismissed hints and which panels you folded.

You can clear them at any time by clearing this site's data in your browser.

Stored on our server

• Bug reports you send from the Code tab: the program, your note, the page and your browser's user agent.
• Play leaderboard: the nickname you submit, your score, the date and the quiz mode. To limit abuse we keep a salted one-way hash of your IP address, never the IP itself.
• Player lookup: when someone looks up a Riot ID we fetch that player's public League data from the Riot Games API (account, rank and recent ranked matches) and cache it so repeat views don't call Riot again. We only show public match data, never rank anyone against other players and keep no accounts.
• Server logs kept by our host (Railway) for operating the site, which may include IP addresses for a short time.

We don't sell or share any of this.

Where our data comes from

• the Riot Games API and Data Dragon (game data, champion and item art, public ranked matches);
• Oracle's Elixir (pro match data);
• Leaguepedia (lol.fandom.com, CC BY-SA 3.0: pro schedules, rosters and team logos).
• Fonts are served from this site; the Play page also loads fonts from Google Fonts.
