Draft Buddy for Sleeper does not collect, transmit, sell, or share any personal
information. There is no account, no analytics, no tracking, and no server
operated by this extension. Everything it stores stays in your own browser.


Stored locally on your device using your browser's extension storage
(chrome.storage.local in Chrome, browser.storage.local in Firefox):

• Your player rankings — whether you built them on the My Rankings page,
  pasted them into the panel, or imported them from a file — along with the
  position, team, bye week and positional rank looked up for each name.
• A copy of the most recent Sleeper ADP board, cached so the page has
  something to show before it next refreshes.
• Your preferences — panel position and size, whether it's collapsed, the
  active position filter, the current sort column, your search text, the polling
  interval, and the panel text size.
• Any players you manually crossed off, stored per draft.

This data never leaves your browser. It is not uploaded anywhere, and the
developer has no access to it. Uninstalling the extension removes it. You can
also clear the saved list at any time with Clear saved list in the
extension's settings.


The extension makes read-only requests to one place, and sends nothing about
you to it.

Sleeper's own public API at api.sleeper.app:

| Endpoint | Why |
|---|---|
| /projections/nfl/{season} | Public half-PPR ADP, and the player names, positions and teams your list is matched against. Cached locally for up to 24 hours. |
| /schedule/nfl/regular/{season} | Derive each team's bye week. |
| /v1/state/nfl | Which season it currently is. |
| /v1/draft/{id} | The draft's team count and type, to label picks as 2.09. |
| /v1/draft/{id}/picks | A fallback source for which players have been drafted. |

Three endpoints earlier versions used are gone: /v1/players/nfl (a ~15MB
download, now covered by the projections call above), and /v1/user/{id} and
/v1/draft/{id}/traded_picks, which existed only to work out which team was
yours — a feature this version does not have.

These are public, unauthenticated endpoints. The requests contain only the draft
ID already visible in your address bar.

The ADP request is made when you open My Rankings with a cached board more than
twelve hours old, or when you press Update ADP. It asks only for public
football data — your rankings are never uploaded, and nothing identifying you
is sent.

Your Sleeper account is not read at all. Earlier versions read your user id
from sleeper.com's own storage to work out which draft slot was yours. That
feature is gone as of this version, and with it the only part of the extension
that ever touched anything identifying you. The extension now tracks the draft,
not your seat in it: it knows which players have been picked and which pick is
on the clock, and nothing about who you are.


The extension runs only on sleeper.com, plus its own My Rankings page. On a
draft page it reads the draft board to see which players have been picked, and
it draws its panel on top of the page. It does not read, collect, or transmit anything else from the page,
and it runs on no other website.


| Permission | Used for |
|---|---|
| storage | Saving your list and preferences locally, as described above. |
| sleeper.com | Drawing the panel and reading drafted players from the board. Also lets the toolbar popup tell whether you're on a draft page. |
| api.sleeper.app | The public API requests listed above. |

• No analytics, telemetry, crash reporting, or usage tracking
• No advertising, and no data sold or shared with anyone
• No remote code — all code is contained in the published package
• No access to your browsing history, other tabs, cookies, or downloads
• No use of your data for creditworthiness or lending purposes

The extension collects no data from anyone, including children under 13.
