Frequently asked questions

What does Coinfetti cost?

The Free plan ($0) includes full naive-vs-gated validation, the AI strategy builder with a monthly quota, starter strategies and the leaderboard. Plus ($9/mo) and Pro ($29/mo) raise the limits and add benchmark comparison and plain-English verdict explanations.

Can I get a refund?

Yes, in full, if it's your first subscription and you email us within 7 days of the first charge. Email is the only channel for refund requests.

Which coins can I test?

A curated catalog of 18 major USD pairs (BTC, ETH, XRP, SOL, DOGE, AVAX, LINK and others). Submission is otherwise open-universe for any USD spot pair with enough history in our data feed.

Where does the market data come from?

Alpaca's data feed — real historical bars with real cost assumptions.

How does the AI strategy builder work?

Describe a strategy in plain English and Claude drafts a formal spec; you always review and edit it before submitting.

Why can't I edit or delete a past run?

By design — the statistical gate counts every attempt at an idea, so submissions and results are permanent, append-only records.

Do you use my strategies to train AI models?

No. Strategies are never used for training and never sold.

Do you track me with cookies?

No cookies, no ad trackers. Login is a token in your own browser; traffic is measured with cookieless, aggregate-only Cloudflare Web Analytics.

What we don't do

We can't provide investment advice or tell you whether to trade a strategy — the service exists to test claims, not to make recommendations.

Coinfetti is a ProveHouse LLC company. Simulated results are past performance, not predictions. Coinfetti does not execute trades, hold funds, or give investment advice.
