## Frequently asked questions

### Can it get me banned?

Quartiy does not inject code into games, read game memory or install a kernel driver. It changes Windows, driver and network settings only, and never touches anti-cheat processes (Vanguard, EAC, BattlEye).

### Is the app in English?

The Quartiy desktop app is in Turkish today; an English interface is planned. Every action is one button with a clear before / after result, and support answers in English.
