Effective Date: Sep 23, 2026
Welcome to Lafter. By accessing or using lafter.gg or the Lafter desktop companion app, you agree to comply with and be bound by the following Terms of Service. Please read them carefully before using our services.
By using Lafter, you acknowledge that you have read, understood, and agreed to these Terms of Service. If you do not agree, you must stop using Lafter immediately.
Lafter is a statistical analysis and drafting companion for League of Legends. It displays publicly available match, summoner, and league data retrieved through the official Riot Games API, alongside analysis we compute from that data (win rates, champion pool trends, team composition scoring, and similar). Lafter does not modify game files, automate in-game actions, or interact with the League of Legends client in any way.
Lafter also hosts spaces for organizations to run League of Legends tournaments, with a draft where captains build teams, mail between accounts, and a help chat.
Lafter is not endorsed, sponsored, or affiliated with Riot Games, Inc. League of Legends and Riot Games are trademarks or registered trademarks of Riot Games, Inc.
Lafter's optional desktop companion, the Lafter Connector, reads data from your own local League of Legends client while it's running and streams it to your Lafter dashboard in real time — such as your current champion select or in-progress game state — so your web dashboard can display it live without you needing to alt-tab. It reads only what your own currently-running client already exposes locally; it does not access anyone else's account, read game memory, inject into the client process, or automate any client or game actions.
You may be required to create a Lafter account to access certain features. You are responsible for maintaining the confidentiality of your account credentials. You agree not to share your account or use another user's account. You may delete your account from your account page; it is deleted seven days after you ask, and you can keep it until then.
An organization's space can be joined with a verified work email address alone (a temp session). Some features, such as accepting a place on a team, need an account. A temp session that makes an account carries its draft profile, offers and form answers over.
Each organization's space is open to people who verify an address at that organization's domain. Your draft profile, rank and mirth are visible to that space's members. Offers and join requests are between players and captains; a place on a team is taken only when you accept it.
Play the Riot account you'll actually be on. An undeclared alt can mean disqualification. A captain can take someone off their team, and Lafter can ban someone from an organization's space; we decide case by case. Tournament rules, prizes and eligibility are the organization's, not Riot Games'.
You are responsible for the mail you send. Don't use it to harass, spam or impersonate anyone.
Feste, the help chat, answers with an AI model from Anthropic. Its answers can be wrong; check anything that matters. Questions are limited per hour and per day, and the chat can be paused or turned off. Don't put personal or sensitive information in it. Feste can flag a message, and flagged messages are reviewed by Lafter's administrators. Misusing the help chat can mean losing access to it.
Violate any applicable laws or regulations.
Violate Riot Games' Terms of Service or API policies.
Attempt to hack, reverse-engineer, or disrupt Lafter or the data it displays.
Use Lafter to harass, scout with malicious intent, or otherwise abuse another player.
Post or share any illegal, offensive, or harmful content through Lafter's shared features, mail or
help chat.
Get around a ban, a usage limit, or an organization's email verification, or try to make the help
chat ignore its instructions.
All original content on Lafter — including our design, code, and computed analysis features — is owned by GangDev or its licensors. You may not reproduce, distribute, or modify any of it without permission. Data retrieved from the Riot API remains subject to Riot Games' own terms and ownership.
We reserve the right to suspend or terminate your access to Lafter if you violate these Terms.
Lafter is provided "as is" without warranties of any kind. Match and account data is sourced from the Riot API and may be delayed, incomplete, or inaccurate at times outside our control. We are not responsible for any losses or damages resulting from your use of Lafter.
Lafter relies on the Riot Games API to function, on Anthropic for the help chat, and may link to third-party sites. We are not responsible for the content, availability, or policies of those third parties.
Your use of Lafter is also governed by our Privacy Policy.
These Terms are governed by the laws of Washington State. Any disputes will be resolved in the courts of Washington State.
