Safety & Anti-Cheat

Is It 100% Safe from VAC Bans?

A technical explanation of how Stealth Idler interacts with Valve's ecosystem without risking your Steam account.

No Memory Injection or DLL Hooks

Valve Anti-Cheat (VAC) is an automated system that scans process memory and module handles for unauthorized DLL injection while connected to VAC-secured game servers (e.g. CS2, TF2). Stealth Idler never attaches to memory, injects code, or loads cheat drivers.

Pure Protocol Emulation

Stealth Idler simply sends an authorized session handshake to Steam's API stating "User is running AppID 1238840 (Battlefield 1)". Steam acknowledges the session and begins the card drop timer. It is mathematically impossible for VAC to trigger on an official API handshake.

Frequently Asked Questions

Everything you need to know before running Stealth Idler on your machine.

Do I need to download or install the games to farm cards?+
No. You do not need to download or install 100GB game files. Stealth Idler simulates your presence using Steam AppIDs directly over the network, saving hundreds of gigabytes of SSD storage and bandwidth.
How fast do Steam trading cards drop?+
Steam's internal algorithm usually begins dropping trading cards after approximately 2 hours of accumulated playtime, followed by additional cards every 30 to 45 minutes until all drops for that badge are exhausted. Stealth Idler manages this schedule automatically.
Can I play another game on Steam while idling?+
Steam only permits card drops when no conflicting interactive game is being played on the same account. If you launch a game, Steam automatically pauses trading card drop timers. We recommend letting Stealth Idler run while you are browsing, watching videos, or away from the PC.
Where are my credentials saved?+
When you log in via the Steam Mobile QR code, an authorized session token is stored exclusively in your local machine's encrypted application storage. Your password is never typed, and no login data is ever transmitted to any external server.
Is Stealth Idler free and open-source?+
Yes. It is completely free, built by Dewzy for enthusiasts and power users who want a clean, fast alternative to legacy software.
