About HoopValuator league reader

HoopValuator league reader brings your Yahoo Fantasy basketball league into your HoopValuator account. What's new in 0.7 - Import keeps going when the popup closes: switch tabs or click away and the import carries on in the background. Reopen the popup to see how far it has got. - One step instead of two: press Import and the league is sent to HoopValuator as soon as it is read. "Open <league> in HoopValuator" then takes you to it. - Easier with many leagues: the status bar stays at the top and the main button at the bottom, however long your league list is. If you are signed out of HoopValuator, the import tells you before it reads Yahoo. Yahoo does not give HoopValuator a way to read your league. Your browser can, because you are signed in to Yahoo. The reader asks Yahoo for your own league from your own browser and sends the result to HoopValuator, where it becomes the league your trade and roster advice is based on. How to use it 1. Sign in to Yahoo Fantasy and to HoopValuator in this browser. 2. Click the extension. It lists your Yahoo NBA leagues. 3. Press Import beside a league. This takes about 40 seconds for a 12-team league, and you can close the popup while it runs. 4. Press Open <league> in HoopValuator. After that, HoopValuator keeps the league current. If your league is more than six hours old, opening HoopValuator refreshes it through the reader, with no popup needed. Sync now, in Settings and beside your league at the top of the page, refreshes it any time. A "Sync when I open HoopValuator" switch in the popup turns the automatic refresh off. You can still import it from the popup. What it reads Your Yahoo NBA leagues, and for the league you pick: its settings, teams, each team's roster, each week's matchups, your own lineup for the next seven days and, in a rotisserie league, the standings. Team names and manager nicknames are part of a league and are included. Manager email addresses are removed in the browser and never sent. What it does not do It never changes anything on Yahoo: no lineups, trades, waiver claims or league settings. It never sees or sends your Yahoo password or login cookies. It talks to two places only: Yahoo's fantasy data service and hoopvaluator.com. Only HoopValuator's own pages can ask it to refresh, and it reads one league at a time. It has no analytics and no advertising. You need a HoopValuator account to use it. Not affiliated with, endorsed by or sponsored by Yahoo. Yahoo and Yahoo Fantasy are trademarks of their owner.
