When you confirm a connection, this extension reads the espn_s2 session cookie
and the ESPN account identifier from SWID (or the swid field in espnAuth).
It sends those two values to FPTrack's servers over HTTPS.
They let FPTrack read your ESPN fantasy leagues, including private leagues.

The popup identifies whether you are setting up a saved Pro connection or a
temporary calculator import. Pro credentials are encrypted in FPTrack's backend
until you disconnect or replace them. Calculator credentials are encrypted in a
temporary backend session that expires after 30 minutes. Unfinished setup sessions
expire after 30 minutes. Cookies are never saved in extension storage or sent to
the FPTrack webpage, the clipboard, analytics, or third-party services.

The extension temporarily stores a connection handoff token in browser session
storage so a background restart can resume the confirmation screen. That token
expires after five minutes and is cleared after confirmation or cancellation.
No browsing history, passwords, messages, or unrelated cookie values are collected.

FPTrack only reads ESPN data. It does not submit ESPN trades, change lineups,
or make waiver claims. Disconnecting in FPTrack removes its saved credentials;
uninstalling the extension alone does not disconnect an existing Pro account.
