Introduction

Lumen is a Discord bot used exclusively in the Unreal Engine Discord server to provide moderation and utility features. This policy explains what data Lumen processes, why, and how it is handled.

Scope

Lumen is not a public bot and operates only inside the Unreal Engine Discord server.

Data Processing

Lumen processes limited Discord data strictly for functionality and moderation:

A. Messages:

• Message content (text)

• Attached or linked images
  Used for:

• Scam detection (text pattern matching)

• Image similarity checks

• OCR based text detection in images

• Triggering automated warnings (e.g., “dm me” in specific forums)

B. Voice Channel Data

• Channel ownership (creator of private VC)

• Allowed/denied user IDs
  Used only to manage private voice channel access.

How the Data Is Used

Lumen uses data only to operate the following features:

• Scam Detection
  Messages and images are scanned using pattern matching, image similarity, and OCR to identify common scam content.

• Moderation Safety Actions
  When scam content is detected, Lumen may:

  • Timeout the user

  • Delete the message

  • Send a DM explaining what happened

• Utility Features

  • Creating and managing private voice channels

  • Sending automated responses to common questions

  • Warning users about risky behavior (e.g., “dm me” prompts)

Lumen does not use data for profiling, advertising, training or analytics unrelated to server moderation.

Data Storage

• Most message scanning is processed in real time.

• Known scam image hashes may be stored in a database of known scam patterns.

• Logs of moderation-related actions (e.g., detected scams, timeouts) may be stored for staff review and abuse prevention.

Lumen does not intentionally store full message histories beyond what is required for moderation logs.

Data Sharing

Data processed by Lumen is:

• Not sold

• Not shared with third parties

Access to moderation logs and detection systems is limited to:

• Bot operators

• Limited server staff

User Control

Because Lumen operates as part of server moderation:

• Users cannot opt out of automated moderation scanning while participating in the server.

• If a user believes Lumen acted incorrectly, they can contact server staff by creating a ticket on the server.
