Track the markets you know and care about.

Yes. One click in your billing settings via Stripe. No calls, no retention reps, no guilt-trip flows.

They stay. Only the most recent N (matching your new tier's cap) remain active. The rest become inactive with a Restore banner. Re-upgrade and they reactivate instantly.

No. We're not a broker. Trade links route to the platforms (Polymarket, Kalshi) where you actually place trades. Chironus is the layer that helps you find and track the markets, not execute them.

Two ways. Subscriptions, which fund the personalization features (filters, alerts, hosting). And small attribution payments from the platforms when trades are routed through our links. The platform side helps us keep the Scanner and our research free for everyone, signed in or not.

The platforms are great for trading. We're the layer for staying on top of them: discovery (finding new markets that match your interests), tracking (alerts on what you follow), and research (News and Learn). The platforms make it easy to trade once you know what you want. We help you know what you want.

We don't sell or share your data with third parties. We use it to personalize your matches, build your digests, and send your alerts. That's it.

Yes. Stripe prorates the difference automatically, and a cancellation keeps Pro running to the end of the period you have paid for.

Partial periods are not refunded, but you can cancel anytime and won't be billed again. At $15 a month the policy mirrors industry norm.

Practice on real markets with simulated money. Every account starts with a $1,000 practice balance; a trade fills at the live ask, marks against live prices while it is open, and settles when the market resolves. No real money is ever at stake and no order is ever placed on Polymarket or Kalshi. Free holds 5 positions open at a time, places up to 5 trades a day, and shows the last 30 days of history. Pro removes all three limits.

Additional alert delivery channels (Telegram, push notifications), and a steady stream of improvements based on user feedback. Watch the changelog.
