About this extension
Playing fantasy football on Sleeper on the desktop is a painful experience. They haven't touched it in years, and I'm just trying to sip some coffee and tinker with lineup while I pretend to work. Good news, I blew the magic conch shell and we are saved!

Conch FF upgrades the UI of your normal Sleeper league to add meaningful data about your team and league, reduce the amount of endless scrolling, and really just rethink each page while keeping it feel like a native Sleeper experience.

The data you see changes with the phase of the fantasy season you're in: Draft Season, Early Season, Late Season, Post Season and for Dynasty and Keeper leagues, Offseason Pre NFL Draft, Offseason Post NFL Draft.

All free, try it out for a bit then turn it off and see the difference. Let's love Sleeper desktop again.

All hail the magic conch!!!!

WHAT IT DOES
• Adds deep and useful data about your team like trends, positional rankings, last year results, and more
• Tunes the spacing, sizing, and coloring of UI
• Dive into history about your leagues, sourced from the Sleeper API
• Hover over data for diving deep into your opponents at a glace
• Rookie draft pick capital and results
• Dynamically show content based on the phase of the season

PRIVACY
Conch FF has no tracking and no analytics. It reads the league page you're
already viewing and fetches public data directly from Sleeper's and
FantasyCalc's public APIs, from your browser. One optional feature (trade
history enrichment, on by default, off in one click) sends the league ID you're
viewing to the developer-operated FF TV Guide API to fetch that league's trade
history — no personal data, anonymous authentication only. Full policy:

sponsored by Sleeper. "Sleeper" is a trademark of its respective owner; it is
used here only to describe what this extension works with.
