The overlay

What it does

It draws this site’s comps over the game while you play. It reads your board, names the comp it is closest to, and shows what the sample says about each augment you are offered — the same numbers, measured the same way, from the same games. How the numbers are made covers the method.

It is an overlay, not a bot: it reads the screen and draws on top of it, and it never touches the game or plays for you.

Installing it

Android only, and not on Google Play — so your browser will ask whether to allow installing apps from it, and Play Protect will show a warning about an app it has not seen before. Both are what Android does with every app that does not come from the store. You will need to allow the overlay to draw over other apps, and accept Android’s screen-recording prompt the first time you start it.

What it asks for

• Draw over other apps — the overlay itself: it is drawn on top of the game while you play.
• Screen capture — how it reads your board. Android shows its own recording notice the whole time, and every frame is read on your phone and stays there.
• Run in the background — so it keeps reading while the game is in front. It stops when you stop it.
• Notifications — the notice Android requires a background service to show.
• Install packages — so it can offer its own updates, since there is no store to do it.
• Internet — to fetch the comp snapshot and champion art. Nothing is sent up.

What it sends

There is no account and nothing to sign in to. The app downloads the comp snapshot from this site and champion art from Riot’s own data files, and that is every request it makes; no screenshot, no match and nothing about your device is ever uploaded. It carries no analytics, no crash reporting and no advertising.

The site is a separate thing and does measure visits, with your consent — the privacy policy says what and how.
