Gridline is a sports analytics platform: probability boards, a daily-fantasy lineup optimizer and college-football slate tools. It is a tool for studying games, not a service that tells you what to bet.
Nothing on getgridlinehq.com, in the app, in exports, or in the API is a recommendation to place a wager. Probabilities are model estimates produced by the process described on this site. You are responsible for your own decisions and your own money. See the disclaimer.
You must be at least 21 years old (or the age of majority for wagering where you live, if higher) to use Gridline, and it is your responsibility to know whether sports wagering and daily-fantasy contests are legal where you are. Gridline does not take bets, hold funds, or process wagers of any kind.
Gridline is not affiliated with, endorsed by, or sponsored by DraftKings, Hard Rock Bet, the National Football League, the NCAA, or any team, league, sportsbook or data provider. Their names and marks belong to them and appear only to identify where public data came from or where a file can be uploaded. Weather data by Open-Meteo (CC BY 4.0). Some college data provided by CollegeFootballData.com.
When subscriptions are open, they are billed by Stripe on a monthly basis at the price shown on the site. You can cancel at any time in the Stripe customer portal (the link is also emailed to you by Stripe); access continues to the end of the period you paid for and then stops automatically. Access is tied to the email you used at checkout: that email is what you log in with. Access given without payment can be withdrawn at any time.
Subscribers can view every board, the Hand Builder, the detail panel for each player, the news and injury feed and the college-football surfaces. They can build their own lineup sets: adjust projections, lock or exclude players, build up to 150 lineups, and download each set as a DraftKings upload file. Refreshing data and administrative controls are operator-only. The operator may change what is included, add surfaces, or retire them.
Don't scrape, mirror, resell or redistribute the boards, the lineup sets, the API responses or the underlying data as a data product. Personal use, study, and use in your own contest entries are fine. Automated access is available only through the API tier and its service tokens.
Gridline runs on a single machine operated by one person. It may be down, late, or wrong. Scheduled jobs can fail; when they do, the app says so instead of showing stale numbers as fresh. We may change these terms; the date at the top moves when we do.
We hold as little as possible: your email lives in Stripe (billing) and in Cloudflare Access (login) and in a small local grant log that records when access was granted or removed and by which route. No tracking pixels, no ad networks, no sale of data. To have your access and email removed, cancel in Stripe and/or email the operator.
Gridline is provided "as is". To the extent the law allows, the operator is not liable for losses of any kind arising from use of the site, the app, the exports or the API — including wagering losses, contest losses, downtime, or errors in third-party data.
