Skin Tracker runs entirely on your computer. There is no account, no analytics and no telemetry.
From your own League client, on your machine, with read-only requests: your Riot ID (shown in Settings), your skin/chroma/emote/icon/ward inventory with purchase dates, your RP / Blue Essence / Mythic Essence balance, and the store and Mythic Shop listings the client already shows you. To talk to the client it uses the local connection details the client itself publishes (its lockfile or process arguments). These are used only on your machine and are never stored or sent anywhere.
In %APPDATA%\SkinTracker: a cache of game data, a saved snapshot of each League account you opened in the client (so the app still opens when the
client is closed, and you can switch between your accounts), your wishlist (with the prices the app noted for wishlisted items), your notifications, your settings, and a small log. Delete the folder to remove all of it.
| Where | Why | What is sent |
|—|—|—|
| raw.communitydragon.org | public game data and images (skin names, art, PBE data) | an ordinary web request (your IP address, program name/version); nothing about your account |
| api.github.com, github.com | check for and download updates | an ordinary web request (your IP address, program name/version) |
Your Riot ID, inventory, balances and wishlist never leave your computer.
If this ever changes, it will be written here and in the release notes.
