Multi-Fantasy Manager and its ESPN companion extension
Manager also stores the Sleeper username and league connections you add, and uses Sleeper’s API to load those teams. Your saved teams are tied to your signed-in account. The public sample dashboard contains example data.

Multi-Fantasy Companion brings your ESPN fantasy football teams into Multi-Fantasy Manager.
What it reads
On ESPN fantasy football team pages, the extension reads the team's name, league and team IDs, season and week, players, lineup slots, league scoring rules, and available points, projections, and player injury status. It checks your signed-in Manager account email so it can save to the account you choose.
It uses your browser's existing ESPN and Manager sessions. It does not read or export passwords, authentication cookies, or ESPN member and owner lists. It does not collect unrelated browsing history.
How syncing works
The extension reads team data while an ESPN team page is open. After you choose Load in Manager and confirm the destination account, it saves that team to Manager over HTTPS. It then checks connected team pages for changes while they remain open. It may briefly open an inactive Manager tab to finish a sync.
This information is used to show and update your fantasy teams. The extension does not sell data or use it for advertising, and contains no analytics. Its use and transfer of user data comply with the Chrome Web Store User Data Policy, including the Limited Use requirements.
What is stored
Your device stores connected team names and identifiers, the destination Manager email, sync preferences, a fingerprint used to detect changes, and pending roster snapshots. Pending snapshots older than 24 hours are ignored when the extension next checks them and removed when its state is next saved. A successful sync removes the corresponding pending snapshot.
Manager stores saved roster snapshots under your signed-in account until you delete them. Manager uses OpenAI Sites and Cloudflare for hosting and storage. These providers process the information needed to operate the service and may retain routine request logs.
Your controls
Pause automatic syncing or disconnect a team from the extension's toolbar popup. Disconnecting removes that team's connection and pending snapshot from the extension. Uninstalling clears the extension's local storage.
Disconnecting or uninstalling does not delete teams already saved to Manager. To delete those snapshots, remove the imported team on Manager's extension setup page. Disconnect it first if you do not want a later sync to add it again.
