Privacy Policy — Fantasy Hall of Fame League Importer

Last updated: September 4, 2026

Fantasy Hall of Fame League Importer is a Chrome extension that creates a user-initiated, read-only connection between a supported fantasy football account and fantasyhoff.com. The current version supports Yahoo, ESPN, and CBS Fantasy Football.

Data the extension accesses

For Yahoo, the extension runs only after you invoke it on a Yahoo Fantasy Football tab and choose Import. It reads the active tab URL to confirm the page belongs to Yahoo Fantasy Football, then reads the fantasy league information Yahoo makes available to that signed-in page: your list of fantasy football leagues and, for each league you import, team names, manager display names and provider identifiers, standings, schedules, scores, draft results, and transactions when available. All requests are made from inside the Yahoo tab using the session that page already has. The extension does not monitor other tabs, build a history of pages you visit, or read or transmit a Yahoo password, cookie, or token. It has no permanent Yahoo host permission.

For ESPN, the extension reads exactly two authentication cookies set in your Chrome profile: SWID and espn_s2. It needs Chrome's cookies permission because espn_s2 is HttpOnly. It does not access cookies from any other website.

For CBS, the extension accesses only the active CBS Fantasy Football league tab after you invoke the extension and choose Export. It reads the active tab URL to confirm that the page belongs to a CBS Fantasy Football league and to identify the league and season. It also reads league information CBS makes available to that signed-in page, including league and team names, manager display names and provider identifiers, schedules, standings, scores, rosters, draft results, and transactions when available. When the Enhanced archive option is on (it is on by default and can be switched off in the extension window), the export also keeps sanitized copies of that league's own CBS report pages, such as history, franchise, transaction, roster and statistics reports linked from the league's history page. Scripts, forms, images, hidden content, chat, and any row that mentions a password, token, or e-mail address are removed before anything leaves the tab, and only that league's own report pages are read. It does not monitor other tabs, build a history of pages you visit, or read or transmit a CBS password, cookie, or bearer token. It has no permanent CBS host permission: the two optional host permissions it declares, for CBS league sites and fantasyhoff.com, belong to a separate session connection feature that is not enabled, and Chrome asks for them only if you choose that feature.

How the data is used

For Yahoo, the extension fetches read-only league responses from the Yahoo tab's own fantasy data origin and transfers the leagues you import to Fantasy Hall of Fame, which validates and normalizes them for the record book. The import can continue in the background after you close the extension window and pauses safely if the Yahoo tab is closed; you can resume it later.

For ESPN, the extension uses the two values to show whether this browser has a signed-in session and returns them to Fantasy Hall of Fame only when you request the connection. Fantasy Hall of Fame validates them against ESPN and uses the authorized session to import the leagues and seasons you select.

For CBS, the extension fetches read-only league responses from the active tab's own CBS origin and transfers the season you chose to Fantasy Hall of Fame. The transfer includes the CBS league host and a canonical league URL, but not the path of the page you were viewing. Fantasy Hall of Fame validates and normalizes the response for the record book. Sanitized report pages from the Enhanced archive are stored encrypted with the rest of the export so later import improvements can re-read them without asking you to export again. Neither provider flow can change anything in your fantasy league.

When data is transmitted

Nothing is transmitted automatically. ESPN authentication information is sent only after a connection request you initiate on fantasyhoff.com. Yahoo league information is collected only after you invoke the extension on a Yahoo Fantasy tab and choose Import, and CBS league information only after you invoke the extension on a CBS league tab and choose Export. The extension accepts handoff requests only from https://fantasyhoff.com and https://www.fantasyhoff.com and verifies the requesting origin before responding. The CBS exporter makes only same-origin requests to the active CBS league host, and the Yahoo importer makes requests only to Yahoo's own fantasy data origin from inside the Yahoo tab.

Storage and retention

The extension does not persist ESPN cookies. CBS and Yahoo handoffs expire after 24 hours. Accepted parts are acknowledged separately so a failed transfer can resume. Collection progress expires after 24 hours of inactivity for CBS and one hour for Yahoo. Completed handoffs are deleted after the site confirms receipt; unfinished collection remains available for retry until expiry. Expired data is removed when accessed or when cleanup next runs. The extension stores no analytics or advertising identifiers.

Fantasy Hall of Fame stores ESPN session values encrypted at rest until you disconnect ESPN or delete your account. For CBS and Yahoo, relayed league data and bounded source evidence are encrypted for reprocessing and diagnosis. CBS HTML is trimmed to exclude scripts and embedded credentials. The server keeps the latest accepted source and recent rejected or unfinished source evidence per season and resource scope. Temporary upload parts expire after 24 hours. Season replacements keep encrypted backups so the previous accepted season can be restored. Account deletion removes these retained records. Removing an export connection in Account → Integrations leaves already imported history and retained diagnostic evidence in place.

Manual connection

The extension includes a manual fallback that places a selected cookie value on your clipboard after you click Copy. The extension does not read or monitor other clipboard contents.

Sharing, sale, advertising, and analytics

We do not sell authentication information or league data. We do not use it for advertising, creditworthiness, lending, or any purpose unrelated to connecting and importing the fantasy leagues you request. The extension contains no ads, analytics, tracking, or remote code.

Data is transferred only as needed to provide the import you request: to Fantasy Hall of Fame, to the applicable fantasy provider for authentication or read-only league retrieval, and to infrastructure service providers that process data on our behalf to host, store, secure, and operate Fantasy Hall of Fame. Those service providers may use the data only to perform services for Fantasy Hall of Fame and must protect it appropriately.

Chrome Web Store Limited Use

Fantasy Hall of Fame's use and transfer of information received from Chrome APIs adheres to the Chrome Web Store User Data Policy, including its Limited Use requirements.

Access and processing are automated. Fantasy Hall of Fame personnel and people working on our behalf do not manually read extension-derived user data unless you give explicit consent for a specific support request, access is necessary to investigate abuse or a security incident, access is required to comply with applicable law, or the data has been aggregated and anonymized for permitted internal operations.

Your choices

Using the extension is optional; Fantasy Hall of Fame retains a manual ESPN connection path. You may disconnect ESPN, delete CBS exports, remove imported seasons, delete your Fantasy Hall of Fame account, remove the extension from Chrome, or sign out of either provider at any time.

Changes

If this policy changes, the updated version and effective date will be posted at this URL. Material changes to extension permissions or data use will also be reflected in the Chrome Web Store disclosures.
