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.

You pick which ones to keep. Free follows up to 10 events, so if you are over that on the switch date you choose which 10 stay (the most recent are pre-selected) and the rest are unfollowed. Nothing is hidden or held for you: an unfollowed event can be followed again later in an open slot. Paper-trading history and journal keep their most recent 30 days on Free; anything older is deleted and does not come back if you re-subscribe.

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

One way: subscriptions. Pro at $15 a month funds the personalization features (alerts, discovery preferences, hosting) and keeps the scanner and the research free for everyone, signed in or not. Chironus has no affiliate links and no affiliate business model. No platform pays for coverage or placement, and nothing is earned when you open an account or trade on one.

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

Your data is never sold or shared with third parties. It is used 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 keeps 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.
