Privacy Policy

Last updated: September 2026

ErrorLedger takes your privacy seriously. This policy explains what information is handled when you use our service and how it is protected.

1. Core Principle: Local-First & Zero-Log Architecture

ErrorLedger runs entirely on client-side web technologies. We do not require any account registration or login, and we never collect or store your personal identity, credentials, or profile data on remote server databases.

2. Browser Local Storage (localStorage) Usage

Solely to preserve your settings and provide work continuity across sessions, the following preference data is saved locally on your device's localStorage:

• Broadcast Games: Participant names, custom wheel items, penalty presets, sound mute states (aether_sound_muted), and theme modes
• Stream Schedule Studio: Active timetable drafts, platform selections, time slot text, and local JSON template export/import configurations
• Scientific MBTI: Temporary quiz state and selected question responses

This data never leaves your device. You can erase it at any time by clearing your browser cache and site data.

3. Chzzk Downloader Local Processing & Cookie Security

The Chzzk Downloader distributed through ErrorLedger is a standalone desktop utility that runs on your local machine (hosted on localhost:5000).

• Zero Remote Transmission: Target video URLs, download progress, and saved MP4 video files are never routed to or stored on ErrorLedger servers. Downloads connect directly from official Naver CDN servers straight to your computer.
• Adult Cookie Protection: If you input Naver login cookies (NID_AUT, NID_SES) to download 19+ age-restricted streams, these credentials remain strictly stored in your local computer memory and are only used for direct session validation with Naver servers. They are never transmitted or logged anywhere externally.

4. Bzzk Security Radar Data Policy

Bzzk Radar aggregates publicly broadcasted moderation actions across live Naver Chzzk channels to help streamers preemptively defend against malicious raids.

• No private chats, direct messages, or personal chatter data are ever recorded or monitored.
• All account identifiers and nicknames displayed on radar boards are 100% automatically pseudonymized and masked to protect user privacy.

5. Scientific MBTI & Psychological Test Privacy

Scoring for the 60-item MBTI test and calculations of the 8 Jungian cognitive function stacks (Ni, Ne, Si, Se, Ti, Te, Fi, Fe) occur 100% client-side inside your browser's JavaScript runtime. Individual responses and test results are never stored or transmitted to remote databases.

6. Advertisements & Third-Party Cookies

To maintain 100% free access for all creators, ErrorLedger may serve non-intrusive advertisements via Google AdSense in compliance with Google's Privacy Policy.

• Standard cookies may be used for statistical traffic analysis and ad delivery. You can opt out of personalized ads at any time via Google Ad Settings.
• Streamer Mode: Appending ?stream=true or ?obs=true to any URL completely disables ad scripts — zero ad cookies are set during live broadcasts.

7. Technical Server Logs

Standard web server logs (IP address, browser type, timestamp, referral URLs) may be temporarily captured for network security, rate limiting, and DDoS mitigation purposes only.
