Calculators

Stakes, odds, and results are computed in your browser and are never transmitted to or stored on our servers.

Aggregate analytics: we use Vercel Analytics to count page views and referrers. It is cookie-free and does not build personal profiles.
Breaking-news alerts (optional): if you turn them on, your browser's push subscription (an anonymous endpoint and keys supplied by your browser) is stored so we can send alerts. Turn alerts off on the News page to delete it.
Bet tracker (optional): bets you log are saved only in your browser's local storage on your device. They are never sent to LineMath, and clearing your browser data deletes them.
Shared links: the “Copy link” button puts your calculator inputs in the web address so you can share them. Anyone with the link can see those numbers, so don't share a link you wouldn't want others to read.
Server logs: our host may keep standard request logs (such as IP address) for security and operations.

If you click a sportsbook link, that company may set its own cookies and track the referral. Their privacy policy governs that data.
