Frequently asked questions
The important bits before installing: price, data, overlay and Riot affiliation.
Is it free?
Yes. The installer is free; download it with the button on this page.
Is my match data sent over the internet?
NO. The app reads match state from the League client's local API on your machine. The internet connection is mostly used for icons, checking for updates and, if needed, fetching a new app version — not to "process" your match in the cloud.
Do I need to sign in to Buildzcrank?
No. We don't ask for a Riot account inside the app: it uses the data the client exposes locally while you play.
How do I get updates?
Buildzcrank can notify you when a new version is available. The installer is designed for easy updates.
Is there a Mac or Linux version?
Windows only for now.
The overlay doesn't appear?
Enable windowed or borderless mode in League of Legends; exclusive fullscreen usually covers other windows.
Do AI suggestions guarantee a win?
No. They help you decide; you play the game.
Does it modify or inject code into League?
No. It's a separate application that reads local info and displays windows on top of your desktop. If third-party software policies concern you, review the Riot policies that apply to your account.
Is this an official Riot product?
No. Buildzcrank is independent.
