Privacy Policy

Last updated November 1, 2026

TFT Luck is a free Windows app, built on Overwolf, that grades the luck of your Teamfight Tactics shops after each game. This policy explains what the app and this website handle, and where it goes.

The short version

Your games are saved on your own computer, and TFT Luck has no accounts. If you say yes to game sharing, each finished ranked game is also sent to us, tagged with a random ID instead of your Riot account, to improve the luck model. It's off until you turn it on, and you can turn it off at any time. Overwolf, the platform the app runs on, and its advertising partners also collect data, under their own policies and your consent choices.

What the app reads

• Game events from Overwolf. While you play TFT, Overwolf's game events tell the app what happens in your game: the shops you're offered, your board and bench, your level, gold and round, and the boards shown at the end of each stage. This is the information the grade is built from.
• Your Riot ID from the League client. The app reads your Riot ID (game name and tagline), your account's PUUID and your region from the League client running on your computer, through its local interface, to label your games. This stays on your computer.

What the app stores

Each game is saved as files in a folder on your computer (you can open it from the app's Settings). If you answer "does this grade match how your shops felt?", that answer is saved there too. You can delete any of these files at any time. Uninstalling the app does not delete them, so remove the folder if you want them gone.

Unless you turn on game sharing, TFT Luck does not send your game data or answers to us or to anyone else. Your Riot ID and PUUID are never sent, even with sharing on.

Optional game sharing

The first time you open TFT Luck, it asks whether you want to share your games to help improve the grades. Sharing is off unless you say yes, and you can change your answer at any time in Settings.

What is sent, once per finished ranked game:

• the game's shop and board data from Overwolf's game events: the shops you were offered, your board and bench, your level, gold and round, the boards shown at the end of each stage, and your placement;
• the grade the app showed you, the model version and rule set that made it, and your thumbs answer if you gave one;
• a random install ID created by the app, so games from the same install can be grouped, plus the app version and game region.

What is never sent: your Riot ID, your PUUID or any other Riot account identifier, your name, or anything outside the game.

Why: only to check and improve the luck model, for example to confirm that grades are fair across many players and to rebuild old games when the model changes. Shared games are not sold, not shown publicly, and not used for advertising.

Where and how long: shared games are stored on servers we control and kept while they are useful for improving the model. To have the games from your install deleted, email support@tftluck.com with the install ID shown in the app's Settings. Turning sharing off stops future uploads.

The other players in your lobby appear in the shared data only as the units on their boards at the end of each stage, with no names or account identifiers.

Ads and Overwolf

TFT Luck is free and shows ads in its own window (never inside the game). Ads are served by Overwolf and its advertising partners, who may collect information such as your device's advertising identifier, IP address and ad interactions to show and measure ads. Where the law requires consent, Overwolf asks for it, and you can change your choice at any time from Settings → Manage ad privacy in the app.

Overwolf also collects usage and diagnostic data about apps running on its platform. That collection is covered by Overwolf's Privacy Policy.
