We make money on Pro subscriptions. We don’t sell your data, we don’t take affiliate cuts from platforms, and we never tell you what to do.

Cancel any time
Stripe portal handles cancellation. Refunds prorated to the day if you cancel mid-period. No retention scripts.
No platform revshare
We don’t take affiliate cuts from Kalshi, Polymarket, or any other platform. The same number reads the same whether you’re reading or trading.
Your data stays yours
Account info is for billing and auth only. Export it as JSON any time from /account. We don’t sell, broker, or train on it.

Questions worth asking.

If yours isn’t answered here, email team@tinycorp.ai. We answer everything.

Is this trading advice?
No. TinyCorp Signal is an exploratory data tool. We publish methodology, calibration, and live data; we never tell you what to do with a market. The whole site is for informational and entertainment purposes. The full disclaimer is in the footer of every page.
Can I cancel any time?
Yes. Stripe handles cancellation from the customer portal linked under /account → Plan. Annual subscribers get the rest of the year and then it stops; refunds are prorated to the day if you cancel mid-period. No retention prompts, no “wait, before you go” screens.
Do you trade on what you publish?
The owner (Dave) trades prediction markets and uses an internal version of these tools to do it. Everything published on the public site is identical to what shows on those internal pages — same data, same methodology, just with the order-placement parts stripped out (which would put us into adviser territory). Forecasts are locked at publish time and never edited; you can audit the history on /calibration.
What data sources do you use?
NWS CLI (the authoritative climate summary Kalshi settles on), NWS METAR with 6-hour RMK groups, FAA aviationweather.gov for 5-minute specials, NWS gridded forecasts (bias-adjusted), Kalshi’s public API, and — starting Week 2 — Polymarket gamma-api and Manifold REST. The full table with refresh cadences is on /methodology.
Is the launch annual price a recurring rate?
No. $110/year is the first-year offer. After 12 months your annual renewal moves to the standard $19.95 × 12 = $239.40, prorated to the day if you cancel mid-period. The first-year price is locked in regardless of what we charge new subscribers later.
Does Pro work without a paid Kalshi account?
Yes. We read public market data and present it; you never have to connect a Kalshi account. The “Open on Kalshi” links go to the public market page — you handle the rest on Kalshi’s side, on your terms.
Is there a free trial of Pro?
The free tier is the trial. It’s real and we keep it real — same data flow, same methodology, no synthetic limits beyond delay and the alert / API features that require infrastructure we have to pay for. If after a few days you decide Pro isn’t worth $19.95/mo, just don’t upgrade. We won’t email you about it twice.
