How to use the client

The same short flow works on Mac and Windows.

01
Install the right build
Choose your platform and processor. The client never modifies the official Codex application files.
02
Create an account or sign in
Use the same account as the website. Your permanent purchases sync automatically.
03
Select Apply to Codex
The client downloads and verifies the selected skin, then asks once before safely restarting Codex.

Restore without signing in

The restore control remains available when your account session or network is unavailable.

Buy once, download again

Both clients read private assets through your account permissions. Downloading again never uses more credits.
