Does signing in grant Sleeper write access?

No. Leagueborn sign-in only controls your saved Leagueborn data. Sleeper access stays read-only and cannot change settings, rosters, lineups, members, or scores.

Does read-only mean Leagueborn stores nothing?

No. Read-only describes what Leagueborn can do to Sleeper. A preview is not saved to your account; a league you choose to save is stored for recaps and history.

Can everyone see a league after it is saved?

No. Saved leagues require an authorized Leagueborn account. A separate share page becomes public only when a member creates the link.

Is a share link confidential?

No. Anyone who gets the hard-to-guess URL can open it. The link makes accidental discovery less likely, but it is not a password.

Data and privacy

Leagueborn data and privacy

Your league stays yours. Previewing a public league starts on the Sleeper fantasy football recaps page. Saving it to your account and sharing a recap are different choices.

Leagueborn never asks for your Sleeper password and cannot change your league. Saving requires a Leagueborn account; anything you choose to share can be opened by anyone with the link.

From preview to saved league

What changes when you save?

A preview reads the public details Sleeper provides so you can pick a league. Nothing is saved to your Leagueborn account until you sign in and choose to keep it.

01 / Preview

See what Sleeper makes public

A public Sleeper username can return your display name and available leagues. It does not require a password or give Leagueborn permission to change anything.

02 / Save

Keep the league in your account

After you sign in and choose a league, Leagueborn can store its seasons, teams, rosters, matchups, scores, moves, drafts, picks, and the records built from them.

03 / Share

Send a public link on purpose

A signed-in member can create a share link. That page may include league and team names, recap text, and the final scores shown in the shared moment.

Product analytics

What Leagueborn measures.

Leagueborn uses an anonymous browser ID to understand basic product activity. The raw ID is hashed before it reaches the analytics table.

What gets recorded

A random anonymous ID stored in your browser.
A hashed version of that ID in the analytics database.
The event, page, a small set of details, and the time.
No raw IP address in the product analytics table.

What this does not cover

Browsers, hosting, networks, databases, authentication, and Sleeper may create ordinary operational logs outside Leagueborn's product analytics table.

A share link is public, not private. Send one only when its league names, recap text, and scores are appropriate for anyone who may receive the URL.

Good to know
