What League Sync does

Dynasty Quant League Sync connects a Fantrax league that you explicitly choose to sync. It uses your existing Fantrax browser session to request league data available to that session and sends that data to Dynasty Quant so we can provide your league workspace.

Data we receive

When you confirm a sync, Dynasty Quant may receive league and team names, manager names, rosters, scoring settings, draft information, trade activity, team logos, and other league data returned by Fantrax for the selected league. We use this data only to operate and improve the Dynasty Quant league experience.

Credentials and sessions

League Sync does not collect, store, or transmit your Fantrax password or Fantrax session cookie to Dynasty Quant. The extension makes Fantrax requests in your browser using your existing signed-in session. A short-lived Dynasty Quant pairing token is used only to associate the sync with the league you selected.

How we share data

We do not sell your data. We do not use synced league data for purposes unrelated to providing Dynasty Quant. We share data only with service providers needed to run Dynasty Quant, or when required by law.

Retention and choices

Synced league data is retained while the league remains connected to Dynasty Quant. League administrators can request removal of a connected league and its stored data by contacting us.
