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