Esports Tracker is a free fan site. It has no accounts and doesn't collect your name, email or anything you type. Here's what does happen when you use it.
Stored on your device
Your settings (no-spoilers mode and how far you've revealed, whether the live stats are expanded, and where you stopped in a rewatch) are saved in your browser's local storage. They never leave your device, and clearing your browser data removes them.
Services your browser talks to
LoL Esports (Riot Games): schedules, results and live game stats are loaded straight from LoL Esports' public feeds.
Riot Data Dragon: champion and item images.
YouTube (Google): rewatches play official videos in YouTube's embedded player, which may set cookies under Google's privacy policy. Nothing loads from YouTube until you press ▶.
Google Fonts: the page font.
Cloudflare: hosts the site and, like any web host, receives standard request information such as your IP address. It may also count visits with Cloudflare Web Analytics, which doesn't use cookies or track you across sites.
Advertising
The site shows a small number of banner ads from Adsterra to cover its costs. Ad providers may use cookies or similar technologies to show and measure ads, and may receive information such as your IP address, browser type and the page you're on. Each ad runs in an isolated frame that can't read this site. You can limit ad tracking in your browser settings or with an ad or tracker blocker.
