Questions, answered

Is the free plan really free?
Yes. Free is free forever — no card, no trial clock, no expiry. You get 10 backtests a day against the full five-year window, and every answer is cited. We only ask for a card if you choose to go Pro.
What exactly is a "backtest"?
A backtest runs the idea you describe — in plain language — across historical US equity data and reports what would have happened, net of costs, with sources for every number. On Free you get 10 a day; on Pro they’re unlimited.
Can I cancel anytime?
Anytime, in one click. Monthly stops at the end of the period; annual is covered by a 14-day money-back guarantee. No emails, no retention maze.
How does student pricing work?
Verify an active .edu email and you get all Pro features at a discount. We re-verify once a year — your price is held as long as you’re enrolled.
Is anything here investment advice?
No. SCHMATZ is a research and education tool. Everything is historical, illustrative, paper-traded, and cited — never a recommendation to buy or sell. Markets are delayed 15 minutes.
