This page works out who to start and what to add in your fantasy baseball
league, and it does that arithmetic in your browser — so it needs JavaScript
switched on.
Your leagues and rosters are kept in this browser's own storage and are not
stored anywhere else. Asking it to read a roster or a free-agent list off
your fantasy platform sends that league's id to this site's API, which
fetches the same public page you could open yourself and keeps nothing.
On Yahoo there is a second way, and it sends nothing here: a reader you add
to this browser reads the Yahoo page you already have open, in the tab you
are already signed into, and hands it to this page in the same browser. That
hand-off is between two of your own tabs — this site's API has no part in it
and is never told your league exists. The only requests it makes are to
Yahoo, from your own signed-in browser, for the same pages you could click
through yourself, and only when you press something.
