Terms of Service

Last updated: 23 July 2026

Welcome to LoL Duel ("the Service"). By using this Service you accept the terms below. If you do not accept them, please do not use the Service.

1. Description of the Service

LoL Duel is an advisory tool for League of Legends. Based on the champion, opponent and lane you choose, it produces item, rune, summoner spell and skill-order recommendations from a mathematical duel simulation. The recommendations are a prediction and guidance; they do not guarantee the outcome of a game.

The Service is free of charge and may be funded by advertising. No feature is hidden behind accepting ad cookies: if you decline, ads are simply shown without personalization and everything works the same. See the Privacy Policy for details.

2. Relationship with Riot Games

LoL Duel isn't endorsed, sponsored or produced by Riot Games. League of Legends and Riot Games are trademarks or registered trademarks of Riot Games, Inc. This Service is offered as an independent, unofficial community tool under Riot Games' "Legal Jibber Jabber" policy. Champion, item and game data come from Riot's public Data Dragon source.

3. Acceptable use

You use the Service only for lawful and personal purposes.
You do not harm the infrastructure by sending excessive automated requests (scraping/flooding).
You do not use the Service to reproduce its source code without permission or resell it commercially.
Client integration (reading live data, writing the rune page) is used only on your own account and in a way that does not violate Riot's Terms of Service. The rune-writing operation uses Riot's supported local client interface; it does not interfere with the game itself and contains no automation/cheating.

4. Limitation of liability

The Service is provided "as is". The accuracy, availability or fitness for a particular purpose of the recommendations is not guaranteed. LoL Duel cannot be held liable for direct or indirect damages arising from use of the Service. Responsibility for in-game decisions rests with the user.

5. Changes

These terms may be updated from time to time. The current version is always published on this page; the date on the page is updated for significant changes.

6. Contact

For any question, request or complaint about the Service, you can reach us at destek@lolduel.com. We aim to reply within a few business days.

Note: This text is a draft that honestly reflects the tool's current operation. Before publishing the Service publicly (especially once ads, membership or payments are added), having it reviewed by a legal advisor is recommended.
