Questions
Good to know
Does Kesin place trades for me?
No. Kesin is a tracker and journal — you place trades on Kalshi or Polymarket directly, and Kesin keeps your P&L, calendar, and analytics in one place. It never has trading control unless you choose to connect a read-only sync.
How does account sync work?
Connect your Kalshi account once and Kesin imports your positions automatically — even while the app is closed — so your P&L stays correct without any manual logging. Polymarket tracking works from your public wallet address.
Is my data private?
Your data is yours. Credentials are encrypted and never shared, and Kesin only ever reads what it needs to show your portfolio. See our privacy policy.
What does Premium cost?
$4.99/month or $34.99/year, with a 3-day free trial. The core tracker — portfolio, calendar, watchlist, and journal — stays free forever.
