The app on your PC

The app is not out to the public yet. This is what it does today. It reads what the League client and the game make available on your PC, and it shows you advice. Most of that reading stays on your PC. Some of it is sent to our server, on its own, without you pressing anything:

During a game, at set minutes, it sends your champion, your role, your rank group, the game minute, and how far ahead or behind you are in minions killed. Our server answers with how players like you usually stand at that minute.

Every three minutes while it runs, it sends the game ids (the number Riot gives each game) of up to 20 of your recent ranked games, so it can learn which role you played in each one. After a game, it sends that game's id. It also sends your Riot player id (a code Riot gives every account), which team you were on, and your rank group, so the server can find you among the ten players and draw your graphs. It sends these again if you open the graph tabs of a review. It downloads our build data for your rank group, so our server can see which rank group that is. It also downloads champion and item data and pictures straight from Riot Games' own picture server, so Riot sees your internet address.

From the loading screen onward, the app can show each enemy's name and the champions they played recently. It gets this from the League client on your PC, which it asks for each enemy's last 20 games. That part is not sent to us. The app also saves some things on your PC: your last game review and the last in-game scoreboard, which both include the names of the ten players, plus your own recent match history and rank. None of these files are sent to us.

The app only ever gives advice. It never plays for you, never presses a key or moves your mouse, and never changes anything inside the game.

Showing it on your phone

This is not built yet. Today the app only answers on your own PC. It does not accept a connection from your phone or from any other device.

The website

Your settings stay on your device. The rank you pick, the way you sort a list, and light or dark mode are stored by your own browser. Clearing your browser data clears them. One thing does reach us: the rank you pick decides which data file your browser downloads from us, so our server records show which rank group that file was for.

There are no cookies and no analytics. We do not use tracking pixels, advertising networks, or any third-party analytics service.

Ordinary server records. Like every website, ours keeps standard access records: the internet address your connection is using, the full web address that was asked for, the time, and the type of browser. The full web address includes anything the app puts in it, such as a game id or your Riot player id. These records come from our web server and from Cloudflare, the service that keeps the site up and fast. We use them only to keep the site running and to spot abuse. We do not use them to build any picture of you, and we never sell or share them. Our intended limit for keeping our own records is 30 days. Cloudflare keeps its own records under its own rules.

Other companies your browser talks to. Our pages load their fonts from Google Fonts, and the home page loads item, rune and champion data and pictures from Riot Games' own picture server. To send these, Google and Riot see your internet address. Cloudflare also asks your browser to report network errors to it, which is error reporting, not tracking.

Looking up a finished game. When the app sends us a game id, our server asks Riot Games for that game's record and keeps a copy for good, so it does not have to ask again. That copy includes the in-game names and Riot player ids of all ten players. Because the app sends the ids of your own games, and sometimes your Riot player id, these requests can be linked to you. The server uses your Riot player id to find you among the ten players in that game.

Riot Games data

Climb Sensei gets its game data from Riot Games, the company that makes League, through a service Riot runs for outside apps. A program on our server asks Riot for the recent games of players, one player at a time, and saves each game. We keep Riot's game records much as Riot sends them. That includes the in-game names and Riot player ids of the ten players, which champion each one picked, what they built, and how it ended, and for many ranked games, how the game went minute by minute. We have no set date for deleting them.

We use these records to work out which builds and picks actually win, so the advice you see is measured rather than guessed. The app also uses them to review a finished game with all ten players in it.

We do not show player names anywhere on this site or in the app's champion select screen. In the app, names can appear from the loading screen onward. We do not sell Riot data, and we do not pass it to anyone else.

Children

Climb Sensei is not directed at children under 13. We never ask anyone their age. Riot's game records do not say how old a player is, so the records we keep may include players of any age.

What we never do

We do not sell data. We do not share data with advertisers. What we do keep is listed on this page.

If you write to us

If you write to us, we hold your email because you chose to send it. Mail to our address passes through Cloudflare's email service and lands in a Gmail inbox, so Cloudflare and Google handle it too. Your email stays in our mailbox unless you ask us to delete it. It is used only to answer you. It goes on no mailing list, it is not used to contact you about anything else, and we give it to nobody else. If you wrote to ask when the app is ready, then telling you is the answer — and once it is sent, nothing further is done with your address.

Ask us to delete it and we will, and we will tell you it is done.

Your rights

We hold no account and no profile for anyone. But if you play League, whether ranked games or ARAM, our copies of Riot's game records may include your in-game name and Riot player id. Our server records may include your internet address. An email you sent us is kept too. If you believe we hold something about you, write to us and we will look and tell you honestly what we find, and delete it if it is there. Write to admin@climbsensei.com and you will get a reply.

Changes

If this page changes in a way that matters, the date at the top changes and we say what changed. We will not quietly widen it.

27 September 2026: corrected. Earlier versions of this page said Climb Sensei collects nothing about you, that nothing the app reads is sent to us, and that we do not store player names. None of that was true. We keep Riot's game records with the in-game names and Riot player ids of all ten players. The app sends game details, your game ids and your Riot player id to our server. The page also left out that Google and Riot see your internet address when our pages load fonts and pictures, and that email passes through Cloudflare and Gmail. The phone section described a feature that is not built yet. Nothing changed in what the site or the app does on this date. The page was wrong, and now it says what they do today. The 19 September note below was written against a page that was already wrong.

19 September 2026: added “If you write to us”, which says plainly what happens to an email address you send. Nothing the site or the app collects has changed. This names something that was already true and was not written down.
