Settings

Open Settings from the sidebar. It has six sections.

Appearance & language

• Appearance: System (follow your computer), Light or Dark.
• Language: English, Tiếng Việt, 中文 or Русский. The change takes effect immediately.

Engine & updates

• Updates shows the Engine in use, the browser build that profiles launch with.
• Chromium Version Manager lists the engine versions you can download:
  • Sync from Cloud refreshes the list.
  • Download installs a version. The first one you download becomes active.
  • Activate switches profiles to another downloaded version.
  • Redownload fetches a version again; the delete button removes it from disk.
  • Cleanup Old deletes every downloaded version except the active one.

The Free plan can keep one engine version installed; paid plans can keep several. See Installation.

Timezone check

Before every launch, Veilus can check whether the profile’s timezone matches where its proxy exits. A profile that goes out through a US IP but reports Vietnam time is easy for a website to spot.

Option	What happens on a mismatch
Block (default)	The profile does not launch; Veilus shows the two conflicting values.
Warn	The profile launches anyway and the mismatch is written to the log.
Off	No check. Launches can be up to about 9 seconds faster, because the check calls through the proxy and then looks up the IP’s location.

To fix a mismatch, open the profile’s Network tab and click Match to proxy.

Notifications

System notifications, sent even while Veilus is hidden in the tray. Turn each one on or off:

• A schedule missed its time
• A scheduled run finished (done or failed)
• Sync hit a profile conflict

System

Run in background: closing the window sends Veilus to the system tray, and schedules keep running. To quit fully, choose Quit Veilus in the tray menu.

• Start with the computer opens Veilus straight to the tray at login, without a window.
• On macOS, the system asks for permission the first time (Background Items Added). Click Allow, or turn Veilus on in System Settings → General → Login Items.

The local API and MCP server have their own page: click Open API & MCP, or use API & MCP in the sidebar. See REST API and MCP.
