Privacy Policy — Headless Horseman Eldorado Sync

Last updated: 2026-07-26

This browser extension exists for one purpose: to copy your existing eldorado.gg login session into the Headless Horseman Lister desktop app running on your own computer, so the app can act on Eldorado on your behalf without asking you to log in a second time.

What it reads

The extension reads the browser cookies set by eldorado.gg only. It requests no other site's cookies, browsing history, bookmarks, or personal data.

Where the data goes

The cookie value is sent to exactly one destination: http://127.0.0.1:8791 — a local server run by the Headless Horseman Lister desktop app on your own machine. It never leaves your computer, is never sent to any remote server operated by us or anyone else, and is never sold, logged externally, or shared with third parties.

Pairing code requirement

The extension will not sync anything until you paste a one-time pairing code generated by your own desktop app into the extension popup. This proves the sync was deliberately authorized by you and prevents any other website or script from triggering a sync.

Storage

The only thing the extension stores (via chrome.storage.local, kept on your device) is the pairing code you enter. No cookie data is persisted by the extension itself — it is read fresh and forwarded immediately each time you sync.
