Remember the quest. Keep the mystery.

xu4 Support turns local game text into a spoiler-aware overlay and optional voice queue. No cloud storage, no permanent upload trail, and no hidden starship autopilot.

“The logs are local. The universe is loud.”

How it moves

Maintained xu4 writes text locally. The support hub reads that stream and presents overlay and voice output without intercepting game state or altering gameplay.

Safe default: DiscoveredOnly — only text you have already seen in your own game is surfaced. Nothing is revealed ahead of your play.

Network posture: no upload or automatic callback. Nothing is transmitted unless you explicitly share a diagnostics archive yourself.
