Privacy

What AllRosters knows about you

Very little. There are no accounts, nothing you enter is stored on our side, and the analytics are anonymous and easy to turn off.

Saved in your browser

The scoreboard keeps these in your browser's local storage, on your device only:

• Your Sleeper username
• Your settings: refresh rate, light or dark, and any leagues you've hidden
• A cache of player names and injury statuses, refreshed every few hours
• Whether you've turned analytics off
• How many times you've visited and whether you've dismissed the add-to-home-screen suggestion, so it isn't shown too often

Clearing this site's data in your browser removes all of it. Your personal scoreboard link (in settings) brings your leagues back.

Sent to Sleeper

To show your leagues, your browser asks Sleeper's public API directly for your leagues, rosters, matchups, projections and live scores, using your username. Those requests go straight from your browser to Sleeper, not through AllRosters. Sleeper's own privacy policy covers what it does with them. AllRosters is not affiliated with Sleeper.

Anonymous analytics

AllRosters uses Google Analytics 4 to learn how the site is used. It records:

• Pages visited, and roughly where visitors come from (country or region, and the site or search that sent them)
• Device type, browser and screen size
• Features used: opening a league, switching tabs or weeks, expanding a player, game or matchup, hiding leagues, adding the site to your home screen, and whether a username entered was found
• How many leagues people follow, in ranges (1, 2–4, 5–9, 10+)

It never records your Sleeper username, league names, team names or players. Usernames are removed from page addresses before anything is sent. Google Signals and ad features are off, the site shows no ads, and Google keeps the data for 14 months. Google Analytics doesn't store IP addresses.

Analytics are off by default for visitors in the European Economic Area, the UK and Switzerland, where only cookieless measurement is sent. If your browser sends a Global Privacy Control signal, analytics don't load at all.

Cookies

The only cookies are Google Analytics' own (_ga and _ga_*), which tell repeat visits apart. They aren't set when analytics are off or in the regions above.
