Terms & Privacy

Terms of Service

TFT ELO (the "Service", available at tft-elo.com) is a free training tool for Teamfight Tactics. By using the Service you agree to these terms.

Use of the Service

The Service is provided free of charge and requires no account, login, or registration for its core evaluation and practice features. You may use it for personal, non-commercial purposes to practice building and evaluating TFT boards.

Optional accounts (ranked Duel)

Ranked Duel — a head-to-head board-building mode with a persistent skill rating and leaderboard — requires signing in with a Google account via Firebase Authentication. Everything else on the Service, including practice Duel against the house, remains account-free. Signing in is optional and is never required to view scores, use the Builder, or practice.

No warranty

The Service is provided "as is" and "as available", without warranties of any kind, express or implied. Board strength scores are model-generated estimates for practice and entertainment only — they are not guaranteed to be accurate and should not be relied upon as authoritative game advice.

Limitation of liability

To the fullest extent permitted by law, the operator of the Service is not liable for any direct, indirect, incidental, or consequential damages arising from your use of, or inability to use, the Service.

Changes to the Service

We may change, add, remove, or discontinue features of the Service at any time, with or without notice. We may also update these terms; continued use after changes constitutes acceptance of the updated terms.

Riot Games

TFT ELO is an independent, fan-made tool and is not affiliated with, endorsed by, or sponsored by Riot Games. Teamfight Tactics game data is sourced from the Riot Games API in accordance with Riot's developer policies and terms of use.

Privacy Policy

We aim to collect as little as possible. Most of TFT ELO — including board evaluation, the Builder, and practice Duel — requires no account and no personal information. Ranked Duel is the one feature that requires signing in with Google, described below.

Information from visitors

We do not collect personal data from visitors beyond standard server logs — such as IP address and browser user-agent — which are used only to operate the Service and prevent abuse. These logs are not sold or shared with third parties.

Google sign-in and ranked Duel accounts

Ranked Duel uses Firebase Authentication (a Google Cloud service) for "Sign in with Google." When you sign in:

• What Google processes: Google handles the sign-in itself and issues a signed identity token to our server. We receive that token and Google's stable per-account identifier (a "UID") from it. Google's own privacy policy governs how Google Sign-In itself handles your Google account data.
• What we store: your Firebase UID, the display alias you choose for the leaderboard, and your Duel rating and match history. We do not store your email address, name, or profile photo — the app only ever reads the UID out of the sign-in token, nothing else.
• What's public: only your chosen alias and rating appear on the leaderboard or to opponents. Your UID and match history are not shown to other players.
• Deletion: to delete your Duel account data (UID, alias, rating, and match history), email andrewyin1010@gmail.com from the address associated with your request. This is a manual process for now (v1); we aim to respond within a reasonable time and will confirm once your data is removed.

Teamfight Tactics match data

Match data used to train and power the Service comes from the public Riot Games API. We store only derived board features — units, star levels, items, traits, and placements. Player identifiers (such as PUUIDs) are used only transiently during data collection and are never displayed or associated with any user-facing content.

Practice-mode scores

Practice-mode scores (Endless, Daily, and practice Duel against the house) are stored locally in your browser and/or in aggregate form, without any personal identity attached — these do not require signing in.
