Climb Sensei is free, it gives advice, and it never plays the game for you. Those three things are most of what is on this page. The rest is the plain wording behind them.
Climb Sensei is a website and a companion app for League of Legends. It looks at millions of games that have already been played and works out which builds and picks actually win. Then it shows you the answer, in your rank, while you play.
Everything here is worked out from past games. Past games are a good guide and they are not a promise. A build that wins more often across a million games can still lose your next one. You decide what to do in your own game. We are not responsible for the outcome of it.
The app reads what League already shows and displays advice beside it. It does not press keys, move your mouse, or change anything inside the game. It does not give you any ability another player does not have. It is a reference book that turns its own pages.
You must not use Climb Sensei to build, feed, or assist any tool that automates play, scripts the game, or breaks Riot Games' own terms. If you do, you may not use this service.
Climb Sensei is free to use. If a paid option is ever added, a free version stays, and we will say plainly what the paid one adds.
There are none. You do not sign up, you do not give us a password, and we never ask you for your Riot account details. Nobody from Climb Sensei will ever ask you for your League login. If someone does, it is not us.
Use it like a normal person would. Do not scrape it in bulk, do not try to break it, and do not resell its output as your own product. The measurements, the writing and the design on this site belong to Climb Sensei.
Climb Sensei uses the Riot Games API and shows public data about games that have already been played. It is an independent project. It is not made by Riot Games, and Riot Games is not responsible for it. Your use of League of Legends itself is governed by Riot Games' own terms, not by ours.
The site and the app are provided as they are. We work hard to keep them right and up to date, and we still cannot promise they will always be available, always be correct, or always suit your purpose. To the extent the law allows, we are not liable for any loss that comes from using them.
If these terms change in a way that matters, the date at the top changes. Carrying on using the site after that means you accept the new version.
