Privacy
Fantasy Football Trade Analyzer and the ESPN Connect browser extension. Last updated October 1, 2026.
ESPN Connect (browser extension)
ESPN Connect has one job: connecting your ESPN fantasy account to Fantasy Football Trade Analyzer, so you can import a league without copying cookies or links.
-
What it reads: only two ESPN cookies,
espn_s2andSWID, and only when the Fantasy Football Trade Analyzer site asks. - Signing in: you sign in to ESPN on ESPN’s own site; the extension never sees your password and never opens, reads or changes any page.
- Your leagues: it asks ESPN for your fantasy profile and passes the list of your leagues to the Fantasy Football Trade Analyzer site.
- Who can ask: only pages on fantasy-trade-analyzer.valabs.workers.dev. Chrome enforces this, and the extension checks it again.
- What it stores: nothing. It keeps no data, has no analytics, and sends nothing anywhere itself.
- What it does not do: read your browsing, other sites’ cookies, or anything on ESPN’s pages.
Fantasy Football Trade Analyzer (the website)
- League data: to analyze trades, our server fetches your league’s settings, rosters and projections from ESPN, and trade values from FantasyCalc. It sends the results to your browser and does not keep them.
- ESPN cookies: for private leagues, the cookies go from your browser to our server in the request, are passed to ESPN for that import, and are never stored, logged or shared, on our server or in your browser.
- News checks: for player news flags, your browser fetches public ESPN news and our server sends a player’s name, projection and recent headlines to an AI classifier (Jev, run on Cloudflare Workers AI with zero data retention). No personal information is included.
- No accounts, ads or tracking. We don’t sell or share data.
Fantasy Football Trade Analyzer is not affiliated with ESPN, Sleeper or FantasyCalc.
