Common questions.
Can I cancel anytime?
Yes. One click in your billing settings via Stripe. No calls, no retention reps, no guilt-trip flows.
What happens to my followed events if I downgrade?
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.
Can I trade directly on Chironus?
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.
How does Chironus make money?
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.
What's the difference between Chironus and just visiting Polymarket or Kalshi directly?
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.
Is my data private?
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.
Can I upgrade or cancel mid-month?
Yes. Stripe prorates the difference automatically, and a cancellation keeps Pro running to the end of the period you have paid for.
Do you offer refunds?
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.
What is paper trading?
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.
What's coming next?
