RedraftCalc ESPN Connector

ESPN doesn't offer a login for third-party sites, so private ESPN leagues can't be loaded with just a league ID. This free Chrome extension fixes that: install it once, click Connect with ESPN on the My League page, and your leagues show up.

Add to Chrome — it's free

How it works

  1. Add the extension to Chrome (desktop). Takes about ten seconds.
  2. Make sure you're signed in at espn.com in the same browser.
  3. Open My League, pick ESPN, and click Connect with ESPN. Pick your league from the list.

Next time you visit, your ESPN connection is remembered in this browser, so it's one click straight to your league. Use Disconnect on the My League page to forget it.

On a phone or another browser?

Chrome extensions only run on desktop Chrome, Edge, and Brave. Public ESPN leagues work everywhere with just the league ID. For a private league on a phone, connect once from a computer, or use the manual option under Advanced on the My League page.

Privacy policy

  • What it reads: two ESPN session cookies (espn_s2 and SWID) from espn.com, only when you click Connect with ESPN on redraftcalc.com. It never reads your ESPN password and can't change anything in your league.
  • Where they go: from the extension to the redraftcalc.com page you're on, which uses them to ask ESPN for your leagues and rosters through RedraftCalc's own server. They are sent to ESPN as part of that request and are not written to any database or log.
  • What's stored: the page keeps the two values in your browser's local storage so you don't have to reconnect every visit. Nothing is stored by the extension itself, and nothing is stored on RedraftCalc's servers.
  • What it doesn't do: no browsing history, no tracking, no ads, no selling or sharing data with anyone. The extension only runs on redraftcalc.com pages.
  • Removing it: remove the extension from Chrome at any time. Click Disconnect on the My League page to clear the saved connection from your browser.
