BLUE LINE BOARD
Privacy policy
Last updated November 10, 2026. Applies to the Blue Line Board extension for Chrome and to this website.
What stays on your device
Blue Line Board reads the Yahoo Fantasy pages of your league that you open, and the league pages it fetches for you while you are signed in, and keeps what it reads on your device only, in the browser's extension storage:
- your league's scoring settings and roster shape
- Yahoo's player ids, matched to the NHL's
- your roster, as your team page shows it
- the free agents seen on the players and Transaction Trends pages
- this week's and next week's opponents' rosters, and this week's past nights as the matchup pages scored them
- your league home page: standings, matchups, transactions and every team's roster, with the team and manager names Yahoo shows there
- this week's opponent's adds, from the league's transactions page
- your league's draft results
- Yahoo's Player Updates and injury report
- the day's goalies with a game and Yahoo's probable starters
- the day's suggested adds
- the pick log of a draft in progress
- your display preferences
- a copy of the daily live feed (public NHL line, injury, goalie and shooting facts) with the time it was fetched
None of it is sent anywhere.
What is downloaded, and what is sent
The projection file ships inside the extension. The live feed is downloaded from our own site (lineboard-chi.vercel.app); that request carries no personal data, no league identifier and no cookie. The extension does not read cookies, credentials or any page outside Yahoo Fantasy. It sends no analytics and no telemetry.
Season pass
Stripe processes the payment and your email under Stripe's own privacy policy. The extension keeps your pass code, a random install id and the day it was installed (the 7-day trial) on your device. Once a day it sends the pass code and the install id to our site, which asks Stripe whether the subscription is active and answers with a renewed code. No league data is sent, and we keep no account database: the subscription's record at Stripe is the only one. After checkout, our page passes your pass code to the extension in the same browser, so there is nothing to paste; the code goes nowhere else.
This website
The site counts page views, clicks on Add to Chrome, emails sent and passes bought, by day and by device type (computer or phone), with no cookie and nothing that identifies you. If you ask us to email you the link, your address is used to send that one message through our email provider, Resend, which keeps its own delivery record. We do not store your address or add it to any list.
Future options
If a future version offers optional aggregate pick statistics or breakage reports, they will be off by default, described here, and contain no names, team names or league identifiers in clear.
Sharing and deletion
Nothing is sold or shared. Uninstalling the extension deletes its storage.
