About FantasyFolio ESPN Connect

Connecting an ESPN league to FantasyFolio needs two cookies: espn_s2 and SWID. They are how ESPN knows a league is yours. The problem is that espn_s2 is HttpOnly. No page script, no bookmarklet and no console trick can read it — by design. So the only way to get it by hand is to open Chrome's developer tools, find Application, expand Cookies, locate the right two rows and copy them without missing a character. This extension does that in one click. Open your ESPN league, click the extension, and both values are typed straight into the FantasyFolio import form in your own tab. Then import as normal. What it does not do: • It makes no network requests of any kind. Not to FantasyFolio, not anywhere. • It stores nothing. No chrome.storage, no local storage, no cache. • It tracks nothing and has no analytics. The two cookies travel from ESPN into a form field in a tab you already have open. Nothing else happens, and nothing leaves your machine except the normal import you then choose to run. The extension only acts on espn.com and fantasyfolio.app, and only in the tab where you clicked it. FantasyFolio grades your fantasy trades on what the players actually scored afterwards. This extension exists purely to remove the developer-tools step from connecting an ESPN league.
