No injection
It does not inject code into games or overlays, and does not read or write game memory.
Security
Is Quartiy a virus? No. Here is what it does and does not do.
Optimization tools change system settings, so it is fair to ask what they touch. Quartiy is a signed-in Windows app that changes Windows, driver and network settings, records every change and can revert all of them.
What Quartiy never does
No kernel driver
It installs no driver and writes no IFEO entries for game executables.
Security stays on
Defender, the firewall, SmartScreen, Windows Update and Device Guard are never disabled by the app.
Anti-cheat untouched
Vanguard, EAC and BattlEye processes are never reprioritised or closed.
How rollback works
Backup first
The previous value of every setting is stored before the change.
One-click revert
Revert one step, a profile or everything from the Support page.
Clean exit
Quitting the app fully reverts its active changes.
Protection mode
Re-applies your chosen permanent settings if a Windows update resets them.
Antivirus warnings
New releases of optimization tools are sometimes flagged by antivirus heuristics before they build reputation. Download only from quartiy.org; if you see a warning, the antivirus guide explains how to check the file.
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).
What data does Quartiy send?
Account and licence checks, and diagnostic packages only when you choose to send them to support.
